DLS 200c Police Scanner

WARNING! It is very important to read the entire user manual before connecting the device.

The DLS 200c is the most advanced police radio scanner on the market. It features 200 built-in channels, distributed across the police L-band (79 MHz), H-band (410-412 MHz), and the general radio band, A-band (79-80 MHz), which covers taxi, fire department, ambulance, and civil defense throughout Sweden. The L-band includes 40 channels (numbered 00, 02, 04, etc., up to 78), the H-band has 100 channels (00-99), and the A-band has 60 channels (00-59). Channel designations, usage areas, and distribution across the country are detailed in the frequency table provided with the device. Channels are scanned in the order A-L-H, at a speed of approximately 100 channels per second. With a few button presses, individual channels or entire frequency bands can be excluded from scanning.

A significant feature of the DLS 200c is its electronic code lock, which allows you to code the device so that unauthorized persons cannot activate it if the power supply to the code lock is interrupted. To avoid finding yourself in a similar situation to a thief, it is crucial to carefully read the chapter "THE CODE LOCK" before operating the buttons.

Placement

The DLS 200c is most easily mounted using the included mounting bracket, which can be screwed onto or under the car's dashboard or into a center console. It can also be placed vertically, if you accept reading the text vertically. However, the controls must be easily accessible with one hand, and the display window must be clearly visible.

Connection to the power supply and a separate speaker is made via an 8-pin screw terminal, which easily snaps onto the corresponding pin socket on the rear panel of the device. This makes it easy to remove the scanner from the car.

Power Supply

The DLS 200c is powered by a 12-volt supply via two positive cables. The red cable should be connected to a power point that is switched off with the ignition key. Otherwise, you risk forgetting to turn the scanner off, and although the power consumption is minimal, the battery can be drained in a few days.

The orange cable connects to a point that has a constant power supply directly from the battery's positive terminal. This powers the device's code memory. (The device's memory for enabled and disabled channels remains even without a constant voltage.) This power supply activates the code lock: if the power is interrupted here, the lock code must be entered to open the device again. See further under the heading "THE CODE LOCK".

The black cable connects to ground (which must be the same as the battery's negative terminal) on the car's chassis. Securely attach the cable to a chassis point that has a stable connection to the battery's ground cable. The DLS 200c can also be connected via a plug in the cigarette lighter socket. (However, in this case, it loses its code memory every time the ignition is turned off and must be opened with your personal code the next time you start.)

The Code Lock

As previously mentioned, it is very important to read and understand this chapter before using your new police radio. This is how the code lock works:

You choose your own code with four arbitrary digits from 1-8, meaning there are over 4000 different combinations. Since the device is completely blocked after 7 failed opening attempts, it is not very likely that an unauthorized person will manage to crack the scanner just by guessing combinations. If you cannot open your device because you have forgotten the code, you must contact Svenska DLS in Göteborg and prove that you are the rightful owner using the certificate that accompanies the scanner. There are no possibilities to bypass the locked electronics through shortcuts, rewiring, or similar methods.

Programming a Code

During programming, the device should be powered on and in search mode. (When the search is manually stopped, this is indicated by a dot lighting up at the bottom right of the display window – this dot should not be visible now.)

We will use an example to show how to load a code into the scanner, which is delivered un-coded. For simplicity, we have chosen the code 1, 2, 3, 4 in the example. Follow these steps:

1. Press and hold buttons 2 and 4 simultaneously.
2. Turn off the device using the on/off button within four seconds.
3. Turn on the device using the on/off button within another four seconds.
4. Press button 1.
5. Press button 2.
6. Press button 3.
7. Press button 4.
8. Wait a second.

The search starts automatically. The scanner is now coded with the code 1, 2, 3, 4.

Changing a Code

The device should be in the same status as when programming a new code, i.e., the search should be active. The following example shows changing the code from 1, 2, 3, 4 to 5, 6, 7, 8. Follow these steps:

1. Press and hold buttons 2 and 4 simultaneously.
2. Turn off the device using the on/off button within four seconds.
3. Turn on the device using the on/off button within another four seconds.
4. Press button 1.
5. Press button 2.
6. Press button 3.
7. Press button 4.
8. Press button 5.
9. Press button 6.
10. Press button 7.
11. Press button 8.
12. Wait a second.

To completely remove the code: Abort the operation after step 7, turn off the device, and then turn it on again. The scanner is now un-coded.

Permanent Channel Exclusion

If you find the radio traffic on a channel uninteresting, it can be permanently excluded. Exclusion is done by stopping the scan with SCAN when the uninteresting channel number is displayed, then pressing OUT. A permanently excluded channel is indicated by all 3 characters in the display window blinking rapidly. The DLS 200c remembers which channels are excluded even after a power interruption, provided the device is turned off with TILL/FRÅN/VOLYM before the power supply is cut. Both permanently and temporarily excluded channels are indicated by a horizontal line lighting up in the lower right part of the display window each time the scan passes such a channel.

Channel Inclusion

To include an excluded channel, follow these steps:

1. Stop the scan with SCAN.
2. Select the correct band with A/L/H.
3. Step to the correct channel with ST-10 and ST-1.
4. Press IN.

To include all channels within a band:

1. Stop the scan with SCAN.
2. Select the correct band with A/L/H.
3. Press and hold IN until the channel letter along with two zeros appears on the display.

Frequency Band Exclusion

To exclude an entire frequency band from scanning, follow these steps (the right column shows the display text if you choose to exclude band A):

In this manner, one or two (but naturally not all three) frequency bands can be excluded.

Frequency Band Inclusion

To re-include band A (from the previous example), follow these steps:

NOTE! For both exclusion and inclusion, IN/OUT must be pressed before the channel letter followed by 00 is displayed. Otherwise, the operation only applies to channel number 00 on the current frequency band. If you don't make it in time: Go back to step 2 and continue from there.

Starting a Coded Device

When you turn on your coded scanner after the power to the code memory has been interrupted, you must "open" it with your personal code.

Follow these steps (if your code is 5, 6, 7, 8):

1. Turn on the device using the on/off button.
2. Press button 5.
3. Press button 6.
4. Press button 7.
5. Press button 8.

Controls on the DLS 200c

Description of front panel controls:

• Till/från/volym (On/Off/Volume): Power and volume control knob.
• SQUELCH: Squelch control knob.
• Buttons 1, 2, 3, 4: Associated with VOLUME, SQUELCH, and code programming.
• Buttons A, L, H: Activation of general band, police low band, and police high band respectively.
• ST-10, ST-1: Channel stepping controls (10 steps and 1 step forward).
• SCAN: Start/stop for scanning.
• OUT: Exclusion of channel/frequency band.
• IN: Inclusion of channel/frequency band.
• Teckenfönster (Display Window): Shows channel numbers, status, and programming information.

Using SQUELCH

The SQUELCH knob controls the reception sensitivity and effectively manages the noise level. With the knob turned fully clockwise, the sensitivity is low. Turning counter-clockwise increases sensitivity, allowing weaker transmitters to be received. However, this also increases noise. A guideline is to turn the knob counter-clockwise until strong static is heard, then turn it back clockwise by 3-5 mm. With a little experimentation, you will soon find a setting that suits you.
