⚠️ WARNING:

Some objects may not be detected because of their composition, size, and location on the subject. If an undetected object passes through the M-Scope, that object may be used as a weapon in a secure area to cause injury or death.

⚠️ WARNING:

The M-Scope should only be used by persons trained and who have a thorough understanding of its operation. If the user of a M-Scope does not follow the operating manual and if the M-Scope is not set up properly, it can allow metal objects to pass through undetected.

⚠️ WARNING:

Metal detectors have been associated with EMI (electromagnetic interference), although much research indicates they pose no threat to pacemakers, medical implants and pregnant women. However, we recommend that any patient or pregnant person concerned about EMI be screened by alternative methods.

Introduction

Fisher Labs is excited to introduce the M-Scope™ Portable Walk-Through Metal Detector! The M-Scope™, the world's most versatile walk-through metal detector, brings Fisher's expertise, innovation and reputation for quality metal detection solutions to the critical and demanding security market.

The M-Scope can be configured in an assembled U-shape for operation or in a stacked 'tote' configuration for transport. Key components include the Control Panel, three Receiver Panels, three Transmitter Panels, and Bases.

Assembly Instructions

1. Begin by selecting the most even and level surface on which to assemble your M-Scope unit. Remove the transport straps and un-stack all the components. Place the two INTERCHANGEABLE base units on the selected ground.
2. Place the control unit on top of the two bases. This ensures that the bases are properly spaced and parallel to one another.
3. If your M-Scope is equipped with the leveling option, proceed with step 3. We recommend that bases with the leveler option be used on uneven surfaces. Hold the base assembly level and engage the push-button levelers by depressing each of the four lever actuators' pushbuttons in turn. Depressing a pushbutton releases its leveler leg, allowing it to drop down to reach the floor. Releasing the pushbutton locks the leg in place. Releasing the leveler legs while the control unit and bases are level to the ground allows the legs to automatically extend to the proper length to hold the M-Scope security gate assembly level. The leveler legs can compensate for low spots in the ground's surface up to two inches deep.
4. The side walls might tip over when they are not connected to each other with the Control Panel. Before assembling the walls, ensure the bases are stable. There are adjustable outrigger supports built into the sides of the bases that are used to increase the width of the bases' stances while the walls are being raised, making the walls less prone to tipping over. Adjust one outrigger by pulling it out part way until it is free to rotate. Rotate the outrigger to the point where its foot contacts the ground, then pull the outrigger all the way out and try turning it slightly in either direction until it locks in place. Repeat this process for all four outriggers.
5. Decide which side of the portal will serve as the entrance and which will serve as the exit. The operator's position is the exit, which is the side facing the LED bar graph and Display Screen. The transmitter and receiver panel positions are determined by the orientation of the control panel. When facing the exit/operator position, the right-hand wall will consist of three transmitter panels, and the left-hand wall will consist of three receiver panels. Incorrect placement of the control unit and panels will prevent them from connecting and locking correctly.
6. There are two types of panels: 'Transmitter' and 'Receiver' panels. Receiver panels have 32 spring-loaded contact pins and one LED on each edge. Transmitter panels have 16 spring-loaded contact pins and no LEDs (just plastic caps). Receiver panels have white labels on the exit side, while Transmitter panels have red labels on the exit side.
7. Place a Transmitter Panel on one base and a Receiver Panel on the other base. Fasten the latches to secure the side panels to the bases.
8. Stack the two remaining Receiver Panels on the receiver side (panels with LEDs). Repeat for the other side. Fasten panels with latches. If the latches do not engage, it means Transmitter and Receiver panels are mixed in the same stack. Ensure all Transmitter panels are on one side, and all Receiver panels are on the other side.
9. Place the Control Panel on top with the wheels over the receiver side (with white labels and LEDs). Latch the Control Panel to the side panels. If the latches do not engage, the Control Panel is installed backwards. The Control Panel will fit onto the side panel even if incorrectly oriented 180°, but the latches will only snap together if the Control Panel is correctly oriented.
10. If you are not tall enough to assemble the unit as described in steps 7 and 8, you can use a small ladder or stepstool, or you may assemble the walls with just two of the panels. Fasten the top panels to the control unit, forming a structure that looks like a table. Carefully lift this assembly onto the existing walls and fasten the remaining latches. Avoid putting stress on the joints between the panels and the control unit by keeping the panels parallel and straight.
11. Push the outriggers back into the bases. ASSEMBLY IS COMPLETE. You may plug the charger into the charger connector on either of the two bases. As long as the unit is powered on, one charger will charge both batteries (one in each base). When the power is off, each base must be connected to the charger individually. Both batteries can be charged simultaneously with the optional “Y Cable”, even when the unit is turned off.

Disassembly Instructions

1. The M-Scope should be powered down (turned off) prior to disassembling the unit, or prior to disconnecting or swapping any of the transmitter and receiver panels. Re-extend the outriggers as in step 4. Undo the control unit's latches and remove the control unit. If you are unable to reach the control panel, undo the latches connecting the top and middle panels, and carefully lift the two top panels together with the control unit, and set it down. Remove the panels from the control unit, and set them aside.
2. Lay out the transport straps on the spot where you will stack the modules for transport. Place the control unit on top of the straps, with the wheel side down.
3. Disassemble the remaining panels and set them aside. Reinsert the outriggers into the bases.
4. If you have the optional leveler, proceed with step 4. Push each of the four leveler legs all the way into the base while holding down their respective actuator pushbuttons, and continue holding them in until you release the actuator pushbuttons. The legs will stay down once the actuators are released.
5. Turn the bases upside down and place them on the control unit.
6. All of the components have projections and indentations designed to nest within each other when stacked for transport. These are called the 'Stacking Features'. They keep the components from sliding around within the stack when strapped together for storage or transport. Ensure the bases are positioned so their stacking features nest securely on the control unit.
7. Stack the panels on top of the bases such that the cones are nearest to the wheel ends of the control unit. Ensure that their stacking features are firmly engaged so that the panels, bases, and control unit all nest together snugly.
8. Fasten the straps securely. Stand it up on its wheel end. THE M-SCOPE IS READY FOR TRANSPORT AND STORAGE. Exercise caution when standing the unit up on its end; the sudden shift in weight may cause the unit to rock away from you. If your car is too small to accommodate the entire unit in one block, simply remove the straps and load the components wherever there is room for them. The entire M-Scope can be loaded into the back seat of a small car. You may wish to un-stack the components and load them individually if the entire unit is too heavy for you to lift by yourself. The M-Scope weighs about 85lbs, which is very light for a security portal, but too heavy for most people to safely lift, unaided.

Strap Installation Instructions

Your M-Scope portable metal detector is equipped with a new Transport Strap. This strap has protective foam cups that will absorb impact occurring while shifting the collapsed device to stand up on end.

Follow the normal Disassembly Instructions of your operation manual on page 9, ensuring the protection foam cups fit over the top 3 panels when stacked.

Getting Started

All of the M-Scope's commands are entered through the twelve-button keypad on the control unit. The two up/down arrows are single function buttons. The other ten buttons labeled 0 through 9 are multi-function buttons annotated with corresponding abbreviations. The following is a list of the complete expressions for those abbreviations:

⚠️ WARNING:

The M-Scope should only be used by persons trained and who have a thorough understanding of its operation. If the user of a M-Scope does not follow the operating manual and if the M-Scope is not set up properly, it can allow metal objects to pass through undetected.

⚠️ WARNING:

Some objects may not be detected because of their composition, size and location on the subject. If an undetected object passes through the M-Scope, that object may be used as a weapon in a secure area to cause injury or death.

Basic Start Up Operation

1. Turn the unit on by momentarily pushing the on/off [numeral 0] button on the control panel keypad. The unit will power up and begin a self-diagnostic check.
2. The LCD will display the Title Screen and the battery voltage during the self-check. The unit will check its seven LED lights on the LED bar graph one at a time, starting with the first (lowest) green one, through the yellow ones all the way up to the last (highest) red one, then back down to the first green one again. After this check is completed, the bar graph display will enter its normal mode, continuously indicating the strength of the received signal it is measuring. Some of this signal may be a representation of various types of electromagnetic noise and interference. During the self-check, the multi-colored, triple zone, alarm indicator LEDs as well as the two multi-colored ready indicator LEDs, will glow red momentarily. Once the self-check ends satisfactorily, they will all change to green. When the M-Scope passes its self-check successfully, the unit becomes ready to detect targets. The user selections will be described elsewhere in this document under the Advanced Functions heading.

Most often, the operator will simply turn the unit on and use the settings already stored in memory. For first-time use, the unit will be set at the Factory Preset setting corresponding to numeral 6/high sensitivity level. Note that these settings may not be appropriate for an operator's unique environment and specific security requirements. A thorough understanding of the M-Scope's operation, and most notably, sensitivity settings, is required for effective, accurate metal detection.

The M-Scope is Multi Language Capable:

To change languages (from a fresh start, with the M-Scope turned off):

1. Press the on button (0) and then rapidly press the down-arrow button [⬇️] and then the up-arrow button [⬆️]. This sequence will bring the unit into the first screen of the diagnostics mode.
2. Pressing the 0 button again will bring the unit into the main screen of the diagnostics mode. While in this screen:
   Pressing the number 1 button will change the menu into English.
   Pressing the number 2 button will change the menu into German.
   Pressing the number 3 button will change the menu into French.
   Pressing the number 4 button will change the menu into Spanish.
   After selecting the desired language, pressing the 0 button will change the unit into the normal operating menus. The M-Scope is now in normal operating mode.
3. When the M-Scope is shut down, the language and other selected options are saved to memory.

Detection and Alarms

Sensing Subjects in the M-Scope

The metal detection alarm decision-making process begins the moment a subject breaks any one of the six invisible beams of infrared light inside the M-Scope's passageway; typically one of the three beams at the portal's entrance. The LED bar graph continuously displays the received signal's strength, but the alarm will not be triggered until something enters the security gate and passes through one of the sensors' light paths.

Going too Fast

Once the M-Scope detects something in the passageway, it begins measuring the elapsed time between when the first beam is crossed upon entering and when the second beam is crossed upon exiting. If the subject exceeds the M-Scope's selected speed limit, the LCD displays "Speed Violation!", the audio alert sounds, the zone lights flash red, and the bar graph and ready LEDs flash several times. These events are logged in the system's internal counters.

Going too Slow

If any of the six light beams remains blocked for more than a few seconds, the unit enters the Photo Detector Blocked alarm mode. This mode features red zone and ready indicator LEDs, an audio alert, and a special LCD screen displaying "Photo Diode Blocked!" along with a graphic of six circles arranged as three pairs, corresponding to the three pairs of infrared LED and Photodiode sensors. Each circle's interior indicates whether the corresponding Photo Detector sensor channel is getting zero signal (blank), a partial signal (partially filled), or a full strength signal (filled). This feature is useful for troubleshooting.

The LED bar graph also indicates which of the six 'electric eye' Photo Detector channels are working properly by flashing:

• LED 1: if the top light beam on the exit side is blocked.
• LED 2: flashes when the middle beam on the exit side is blocked.
• LED 3: flashes if the bottom beam on the exit side is blocked.
• LEDs 5, 6, 7: correspond to the top, middle, and bottom light sensor channels on the entrance side. These LEDs glow steadily (without flashing) to indicate good Photo Detector channels in this alarm mode.

Finding Metal Targets Without Speed Violations

While the portal is occupied, the zone lights stay green, the status light glows yellow, and the ready lights glow red. The LED bar graph reflects the received signal strength actively. If none of the three zones received a target signal strong enough to exceed the current alarm threshold, the zone and ready lights will turn green again when the subject exits. This event, like all others, is logged automatically, and the M-Scope is ready to scan the next subject.

Zone Indication

The M-Scope has three zones. If one or more zones detect target signals strong enough to exceed the alarm threshold, the audio alert sounds, and the LED bar graph flashes. The zone indicator light corresponding to the zone with the strongest signal glows red. Other zones that detected a signal strong enough to exceed the threshold will repeatedly change color between red and green, appearing yellow. Zones that did not receive a threshold-crossing signal continue to glow green. Only one zone indicator can glow red at a time. No more than two can glow yellow (alternating red and green) at a time. Any combination of green zone indicators is possible.

After finding target(s), the audio alert continues to beep and the alarm indicator lights flash for about five seconds before the M-Scope indicates readiness to accept the next subject with a steady green ready light.

Key Stuck Alarm

When any key is held down for more than twenty seconds, the bar graph LEDs go dark, the zone and ready indicators turn red, and the LCD screen shows "Key Is Stuck!". It also shows a representation of the keypad with properly functioning keys having dark numerals on light backgrounds, and the stuck key showing light numerals on a dark background.

Shut Down Sequence

To shut down the M-Scope security gate, press the shut down key [numeral 0]. The LCD will show "SHUTDOWN STARTED." You must press the numeral 1 key within five seconds of the shutdown screen's appearance to complete the shut down process, or else the system will return to the normal operating mode. The LED bar graph illuminates singly, in descending order, marking the stages of the shutdown process.

The M-Scope has an automatic self-shutdown safeguard that prevents complete battery drainage. If the battery level is too low, the unit automatically shuts down and remains off until the battery is sufficiently charged or the battery charger is plugged in.

Battery Low Alarm and Recharging Methods

The M-Scope is powered by sealed lead-acid batteries. Keeping a load on batteries when their voltages are too low will eventually destroy them; the M-Scope design prevents this. When the battery voltage gets too low (e.g., < 11 Volts), the LCD announces “Low Battery Alarm” along with the batteries' voltage level and the time remaining before the unit shuts itself down. After the unit shuts down, keep it off and charge both batteries for several hours before continued use. There are three ways to fully charge the M-Scope:

• Shut the unit off and charge each base alone for up to twelve hours. You must charge both batteries as unbalanced batteries can cause errors.
• Shut the unit off and charge both bases together with the Y-Cable for up to twelve hours.
• Turn the unit on and leave it running for 24 hours or more until the display shows the voltage is over 12 volts.

Note: Always try to charge batteries before the “Battery Low Alarm” appears. There is no danger of overcharging the batteries.

The battery charger/power supply will fully charge both M-Scope batteries while in use. Charging time is approximately 24 hours.

M-Scope batteries can also be fully charged and maintained while in storage by using the battery charger/power supply with the optional Y cable assembly. Charging while in storage takes approximately 8-12 hours.

Outside Interference

If one or more of the M-Scope's panels are not ready to detect targets, it could be due to outside interference. A panel not ready to detect is indicated by the zone indicator LED glowing red, and the ready LEDs on the entrance and exit sides of the M-Scope control panel glowing red. The unit will then be ready to detect targets when the panel and ready LEDs turn green. This should only take a few seconds.

If the M-Scope is set up in an area where interference occurs, the unit may not function properly. Try moving the unit to an area where the panel and ready LEDs glow green, and there is an acceptable level of ambient signal as indicated by the LED bargraph.

Advanced Functions

1. Volume Menu

Programmable "Target Detected!" Alarm Length

When an object is detected, the M-Scope displays "Target Detected!" and sounds an audible alarm. The default duration for this alarm is four seconds. This feature allows this alarm to be adjusted to the user's preference of one, two, three, or four seconds.

Instructions: Access the Volume Menu by pressing "1" on the keypad and the Volume menu will display. Press "1", "2", "3", or "4" to change the number of seconds an alarm will sound when a metal object is detected. The stopwatch symbol displays the current setting. Press "0" to exit the Volume Menu.

Programmable Alarm Pattern

When the M-Scope detects metal, it sounds an audible alarm. This alarm is an adjustable beeping pattern the M-Scope generates. With this feature, there are thirty-two unique alarm patterns to select from.

Instructions: Access the Volume Menu by pressing "1" on the keypad. Press "7", "8", or "9" to change the alarm beep pattern. There is no visual indication of your choice, but the pattern you select is heard while the Volume Menu is displayed. Press "9" to advance to the next available choice. Continue pressing "9" to advance through additional choices until a satisfactory alarm pattern is found. Press "7" to go back to a previous choice. Press "8" at any time to reset the alarm pattern to a steady tone. Press "0" to exit the Volume Menu.

Alarm Volume

Adjust the Audible Alarm Volume.

Instructions: Access the Volume Menu by pressing the "1" button. While in the Alarm Menu, the currently selected volume setting is displayed graphically and can be heard. Press the Up Arrow [⬆️] to increase the volume or press the Down Arrow [⬇️] to reduce volume. Press "0" to exit the Volume Menu.

2. Sensitivity Menu

The sensitivity setting determines the unit's ability to detect metal objects. The higher the sensitivity, the more responsive it will be to relatively small metal concentrations. To adjust the sensitivity, press the sensitivity key (numeral 2). Use the up/down arrows [⬆️/⬇️] to adjust the sensitivity setting to any number from 1 to 99. Sensitivity settings should be selected and adjusted based on your facilities' particular security needs and operating environment. The M-Scope will retain your sensitivity settings in memory when you turn the power off.

Zone Settings

It is possible to adjust the individual zone sensitivities to fine-tune the performance of the M-Scope. Once in the sensitivity menu, press any key other than the Up, Down, or 0 button. This will display the Zone select screen. The three bar graphs and numerical readings represent the settings for the TOP, MIDDLE, and BOTTOM zones. These settings range from 0.00 (zone ignored) to 2.00 (twice the sensitivity of the main setting). A value of 1.00 corresponds to a zone having an equal setting as the sensitivity menu. Pressing numerals adjusts the settings for the zones. Pressing numeral 1 decreases the sensitivity for the top zone. Pressing numeral 2 resets the top zone to 1.00. Pressing numeral 3 increases sensitivity to only the top zone. Buttons 4, 5, and 6 adjust the middle zone settings. Buttons 7, 8, and 9 adjust the bottom zone settings. Pressing the Up, Down, or 0 numeral returns to the Sensitivity Menu.

3. Contrast Menu

To adjust the LCD display contrast, press the contrast key (numeral 3) when the M-Scope is in normal operating mode. Use the up/down arrows [⬆️/⬇️] to adjust the contrast. Contrast settings are automatically saved into memory. Press numeral 0 (or wait ten seconds) to exit the contrast menu.

4. Counter Menu / Statistics

To view the counters' contents, press the counter key [numeral 4] while the M-Scope is in normal operating mode. The LCD will display the four counters' names (people counter, metal target counter, speed violations counter, access alarm counter) and their stored values. To reset the counters, press the numeral 1 key. Press numeral 0 (or wait ten seconds) to exit the counter menu.

5. Rate Alarm Menu

To access the rate alarm menu, press the rate key [numeral 5] while the M-Scope is in normal operating mode. The LCD will show the rate alarm setting. There are six possible speed settings, including the disable rate alarm setting (e.g., 0.2m/S, 0.5m/S, 1.0m/S, 1.5m/S, 2.0m/S, Disabled). All rates are expressed in meters per second. Use the Up/Down arrows [⬆️/⬇️] to adjust the rate alarm setting. Press numeral 0 (or wait ten seconds) to exit the rate alarm menu. If the rate alarm is not set to DISABLED, a subject taking too long (more than 7.5 seconds) to exit the M-Scope will also cause a speed violation.

Entrance-Only Active Mode

While in the Rate Alarm Menu, a user can choose to set the M-Scope to an "Entrance-Only Active" mode. In this mode, the M-Scope alarms and counts people that enter the unit through the entrance only, and ignores those entering through the exit side. The “Entrance-Only Active” mode can be set by pressing the numeral 5 key while in the Rate Alarm Menu. “Entrance-Only Active” will be displayed in the rate alarm menu and on the title screen when powering the unit on. This function is useful for screening people entering an event without screening or acquiring statistics when they are leaving.

To return to the normal operating mode (the alarm and counter are active when people enter through the entrance and exit), press the 5 key again, while in the Rate Alarm Menu.

6. Access Menus / Password Protection

Access to adjustable parameters such as sensitivity and rate alarm settings, and to the statistics counters, may be password protected using the features found on the Access menu. Pressing the Down arrow key [⬇️] while the M-Scope is in normal mode opens the access menu. If the Access feature is enabled, the LCD screen will prompt you to enter the current access code. The M-Scope's factory default access code is 01. The default access code will remain 01, until it is changed by a user.

• System will respond to an incorrect access code entry by displaying "Code Mismatch!".
• After each unsuccessful attempt, the system will display "Access Denied" and the event will be logged in the statistics counter under the Access alarm counter heading.

There are locations for storing four different access codes, for use by different individuals. Location 1 is the Master 1 access code location. Whenever the M-Scope is password protected by Access enable, a Master level password is needed to access:

• 1. Change the sensitivity level
• 2. Access the counter menu
• 3. Change the rate alarm setting
• 4. Edit the access codes
• 5. Change/Access Presets

User level access codes allow changes to be made to the volume and contrast. No access code is needed to turn on or off the unit. When you open the access menu with a Master level code, you can choose between access enabled and access disabled by pressing the numeral 5 key.

Access Menus / Password Protection (Continued)

Editing the access menu is the way to change access codes, and enable or disable the access protection feature.

To change an access code, open the Edit access menu, and then press the numeral key corresponding to the code location you wish to change (e.g., press numeral 1 to change the Master 1 access code). This will open the Reset access code screen.

Enter the new code. The code can be of any length from one through ten digits long. If no key is pressed within four seconds, the system will revert back to the Edit Access screen. Because there is no Enter key, and the code password length is not fixed, you must wait for the four-second timeout after you finish entering your new code.

Four seconds after entering the new User 2 code, the system will switch to the Re-enter access code menu, and prompt you to verify the new code by re-entering it.

If the two entries do not match, the system will display "Code Mismatch!" and return to the Reset access code menu after a four-second pause.

After the new user code has been successfully entered and verified, the system will open the Code saved menu. This feature allows the status of the newly stored access code's user to be assigned either User or Master status. Each time the numeral 1 key is pressed, the code saved menu screen will alternate between displaying User and Master. User #1 always has Master's status. Press the Numeral 0 key to return to the Edit access menu. Press numeral 0 (or wait ten seconds) to exit the Access menus.

Default Codes:

• MASTER 1 = "01"
• USER 2 = "1"
• USER 3 = "2"
• USER 4 = "3"

WARNING: Please protect your password. A lost password can only be reset with the assistance of the technicians at Fisher Labs.

Presets

The M-Scope's ideal group of settings may change with different users' individual preferences or in different security applications. The M-Scope can store three separate groups of settings under the headings of User Presets 1, 2, and 3, corresponding to numeral keys 7, 8, and 9 respectively. A fourth group of settings, called the Factory Presets, corresponds to the numeral 6 key. To configure the M-Scope to use any of these four Preset groups, simply press the corresponding numeral key when the M-Scope is in normal operating mode. For example, pressing the numeral 8 key will set the M-Scope to the configuration stored in User Preset 2.

When you receive your M-Scope, Presets 1, 2, 3, and the FP (Factory Preset) will be saved to the following levels. Before using the M-Scope in any application, all target types and sizes of interest should be passed through the M-Scope to properly select the appropriate sensitivity settings.

Factory Preset (high sensitivity level)

• MAIN SENS: 50
• TOP ZONE: 1.00
• MID ZONE: 1.00
• BOTTOM ZONE: 1.00

PRO1 (memory #1) (medium-high sensitivity level)

• MAIN SENS: 80
• TOP ZONE: 1.30
• MID ZONE: 1.00
• BOTTOM ZONE: 1.80

PRO2 (memory #2) (medium sensitivity level)

• MAIN SENS: 45
• TOP ZONE: 1.30
• MID ZONE: 1.00
• BOTTOM ZONE: 1.50

PRO3 (memory #3) (low sensitivity level)

• MAIN SENS: 20
• TOP ZONE: 1.00
• MID ZONE: 0.80
• BOTTOM ZONE: 1.20

To assign a group of settings to one of the User Presets, adjust the M-Scope's variables as discussed in the preceding instructions, and then press and hold the corresponding numeral key for at least one second to store the settings. Note: The Factory Presets cannot be changed.

If the M-Scope is password protected (Access enabled mode), the system will prompt the operator to enter their password or Access code. Changing the values in any of the three User Presets while the unit is in Access enabled mode requires a Master level access code.

Diagnostics Screens

The M-Scope has a Diagnostic Mode that can be used to check the performance of its six Photo Detector channels and its three separate metal detector zones. It is also useful for exercising all of the system's various LEDs. This mode was not designed for M-Scope operators' use. Misusing it cannot damage anything, so its operation is described below.

To enter the diagnostic mode, begin with the power to the M-Scope turned off. Turn the power on, and quickly press the down arrow key [⬇️], then the up arrow key [⬆️], then wait for the unit to complete its LED sequencing self-test pattern. Each of these arrow key presses must be done within two seconds of powering on.

This is a diagnostics mode entry screen. It displays the software date and version information. If you need to contact the manufacturer about your unit, include this information in your correspondence. Press any key to exit the diagnostics mode entry screen. Press the 0 key twice to return to normal operating mode.

The operational diagnostic mode screens show the six Photo Detector channels' states. Open, light-colored ovals represent channels receiving a full power light signal. Filled, dark-colored ovals represent blocked channels. Channels receiving only partial illumination are depicted by partially filled ovals.

The alphanumeric characters between the pairs of ovals represent the magnitudes of the three zones' most recent target measurements, expressed in hexadecimal engineering units. These values vary with the system's sensitivity setting. Diagnostic mode target measurements are made by passing a target through the portal, across the Photo Detectors' paths, as in normal mode. The time it takes the target to go through the Photo Detectors' paths is shown in units of seconds, displayed as Δt=xxS.

LED Testing

The LEDs can be controlled manually while in the diagnostics mode by pressing the different numeral keys. Duration is approximately 4.5 seconds, then returning to diagnostic mode. The ready light will go green and the LED bar graph displays the signal strength.

Tips & Troubleshooting

1. M-Scope batteries typically need to be changed after two or three years. Weak batteries may lead to several problems and error messages, including blocked photo diodes. Many error messages can be corrected by recharging both batteries to a full charge. There is no danger of overcharging the batteries. If a new battery is needed, always change both batteries together, as improperly balanced batteries can create error messages.
2. Unit comes on and then cycles off: Check the battery voltage. If below 10.9 volts, recharge the batteries completely or hook up the charging unit. The voltage must be above the 10.9 range or the unit will not come on.
3. Unit tries to come on but won't power up: Check the position of all transmitter and receiver panels and ensure they are placed properly, and that the top is put on correctly. There are red and white strips under the latches used to help with correct panel placement.
4. Unit comes on but has no display on screen (blue screen): Press the number 3 key on the control panel and use the up arrow until the screen contrast returns to the desired level, or press the factory preset key #6 or any of the user preset keys #7, 8, or 9.
5. Unit comes on but has a blocked photo diode: Disassemble the unit and reassemble it, placing the receiver panels in a different order. Check for proper placement of the bases. If the unit still shows a blocked diode but in another location, the panel will need to be replaced. Make sure the unit is placed on level ground so that the panels are parallel with each other. Bases with the leveler option are recommended for uneven surfaces.
6. Unit is plugged into the charger but the voltage isn't going up: Make sure the AC plug is plugged into a live outlet and that the charger output plug is pushed all the way into the unit and making good contact.
7. To switch unit to operate at 50/60 Hz mode: In diagnostic mode (see page 23), press the up button [⬆️] to toggle between 50/60 Hz. When operating in countries with 60 Hz AC power, the 60 Hz mode should be selected. Conversely, when operating in countries with 50 Hz AC power, the 50 Hz mode should be selected. 50 Hz will not operate correctly within a 60 Hz environment, and vice versa.
8. Fisher recommends that all M-Scope units intended for outdoor use be used with the Weather Protective Package option. This option includes a pop-up shelter that shields the M-Scope from direct sunlight (UV rays) and rainfall. It also includes a mat to keep the bases from getting excessively dirty.
9. Fisher recommends that when using a handheld weapons detector in conjunction with the M-Scope, the handheld operator stand approximately three feet or more from the M-Scope to avoid interference. Also, two M-Scopes placed side by side should be separated by three feet or one meter to avoid electro-magnetic interference from each other.
10. Remember that the M-Scope's factory default access code is 01. Should you forget your code, contact Fisher Labs for instructions on how to reset the code (info@fisherlab.com). The default access code will remain 01 until it is changed by a user.
11. Remember that when storing or transporting your M-Scope, secure the latches in their locked position to prevent them from bending or breaking.
12. Remember the following tips for caring and maintaining your M-Scope: Check the spring contact pins and boards for dirt and debris; clean with a toothbrush and alcohol. When cleaning, use a damp cloth only. Do not submerge the bases or place them where they might get rain runoff. Do not use the M-Scope in direct rain. If the M-Scope gets wet, turn it off immediately, disassemble it, wipe external surfaces dry, and shake individual parts to remove water from inside. Allow the unit to thoroughly dry before reassembling and turning it on. If you experience trouble after allowing the unit sufficient time to dry, contact the factory.
13. M-Scope is alarming indicating “Target Detected” even when people walk through with little amounts of metal: Reset M-Scope sensitivity settings and test again. To lower overall sensitivity, press # 2 then the down arrow [⬇️]. Many guns can be detected at an overall setting of 20% or less. A good calibration starting point is with the overall sensitivity at 20% and the three individual zones set to their midpoint (50%). Any calibration setting should be thoroughly verified by multiple passes through the M-Scope with the target metal at various points on the body. It should be re-verified on a routine basis to account for fluctuations in electro-magnetic interference and other environmental factors.
14. Check for electro-magnetic interference. It may occur when the M-Scope is placed in very close proximity to a motor, a screen (TV or computer), or certain types of fluorescent lighting. The most common result is that the M-Scope will alarm (indicating “Target Detected”) when people are carrying very small amounts of metal, even when the M-Scope is set to a very low sensitivity (below 5%). One solution is to turn the M-Scope sideways by ninety degrees. If that is not possible or does not work, it is recommended that the M-Scope be moved to a new location a few meters away; a change of just a few meters often eliminates interference.
15. Keypad is not functioning correctly: Pressing certain numbers has no result, especially if the non-functioning numbers are in a straight line (e.g., 2-5-8-0). Contact factory for service.
