Programmable Switch The transmitter can also be configured as a "one button" device by locking the ability to make changes with the keypad, and configuring the top panel switch as either power on/off or a mute function. Modulation Indicator LEDs When the transmitter is set to MUTE, the -10 Modulation Indicators LED will glow solid red. Otherwise, the -10 Modulation Indicators LED will glow solid green when transmitter is on. Belt Clips The wire belt clip may be removed by pulling the ends out of the holes in the sides of the case. Be sure to have a firm grip to avoid scratching the surface of the housing. An optional spring-loaded, hinged belt clip (model number BCSLEBN) is also available. This clip is attached by removing the plastic hole cap on the back of the housing and mounting the clip with the supplied screw. IR (infrared) Port The IR port is available on the top of the transmitter for quick setup using a receiver with this function available. IR Sync will transfer the settings for frequency from the receiver to the transmitter. Remove hole cap to attach spring loaded belt clip www.lectrosonics.com 3 Battery Installation The transmitter is powered by two AA batteries. We recommend using alkaline, lithium, or rechargeable batteries for longest life. The battery status circuitry compensates for the difference in voltage drop between alkaline and lithium batteries across their usable life, so it's important to select the correct battery type in the menu. Because rechargeable batteries run down quite abruptly, using the Power LED to verify battery status will not be reliable. However, it is possible to track battery status using the battery timer function available in the receiver. Push outward on the battery compartment door and lift it to open. Slide door out to release catch Lift door to open Insert the batteries according to the markings on the back of the housing. If the batteries are inserted incorrectly, the door will close but the unit will not operate. The battery contacts can be cleaned with alcohol and a cotton swab, or a clean pencil eraser. Be sure not to leave any remnants of the cotton swab or eraser crumbs inside the compartment. 4 LECTROSONICS, INC. Contact springs Battery Status LED Indicator Alkaline, lithium or rechargeable batteries can be used to power the transmitter. The type of batteries in use are selectable in a menu on the LCD. When alkaline or lithium batteries are being used, the LED labeled BATT on the keypad glows green when the batteries are good. The color changes to red when the they are nearing the end of life. When the LED begins to blink red, there will be only a few minutes remaining. The Power/Function LED on the top panel will mirror the keypad LED unless the programmable switch is set to Mute, and the switch is turned on. The exact point at which the LEDs turn red will vary with battery brand and condition, temperature and power consumption. The LEDs are intended to simply catch your attention, not to be an exact indicator of remaining time. A weak battery will sometimes cause the Power LED to glow green immediately after the transmitter is turned on, but it will soon discharge to the point where it will turn red or the unit will turn off completely. Rechargeable batteries give little or no warning when they are depleted. If you wish to use these batteries in the transmitter, the most accurate way to determine runtime status is by testing the time provided by a particular battery brand and type, then using the BatTime function to determine remaining runtime. NOTE: Refer to the Main Menu and Setup Section of your manual for BatTime details. www.lectrosonics.com 5 Operating Instructions Powering On in Operating Mode Press and hold the Power Button for several seconds until a moving bar on the LCD progresses.

Audio Mute or Talkback status Frequency (MHz) DBu MUTE 470.100 -40 -20 +0 RF On/Off Status Battery status Audio level If the programmable switch function is set for Mute or Talkback, the Main Window will indicate that the function is enabled. 8 LECTROSONICS, INC. Menu Item Descriptions Input Gain Gain can be set, from -7 to +44, by using the and arrow buttons. Adjusting the Input Gain The two bicolor Modulation LEDs on the top panel provide a visual indication of the audio signal level entering the transmitter. The LEDs will glow either red or green to indicate modulation levels as shown in the following table. Signal Level -20 LED -10 LED Less than -20 dB Off Off -20 dB to -10 dB Green Off -10 dB to +0 dB Green Green +0 dB to +10 dB Red Green Greater than +10 dB Red Red NOTE: Full modulation is achieved at 0 dB, when the "-20" LED first turns red. The limiter can cleanly handle peaks up to 30 dB above this point. It is best to go through the following procedure with the transmitter in the standby mode so that no audio will enter the sound system or recorder during adjustment. 1) With fresh batteries in the transmitter, power the unit on in the standby mode (see previous section Powering On in Standby Mode). 2) Navigate to the Gain setup screen. Gain 25 -40 -20 0 3) Prepare the signal source. Position a microphone the way it will be used in actual operation and have the user speak or sing at the loudest level that occur during use, or set the output level of the instrument or audio device to the maximum level that will be used. www.lectrosonics.com 9 4) Use the and arrow buttons to adjust the gain until the 10 dB glows green and the 20 dB LED starts to flicker red during the loudest peaks in the audio. 5) Once the audio gain has been set, the signal can be sent through the sound system for overall level adjustments, monitor settings, etc. 6) If the audio output level of the receiver is too high or low, use only the controls on the receiver to make adjustments. Always leave the transmitter gain adjustment set according to these instructions, and do not change it to adjust the audio output level of the receiver. Rolloff (Low Frequency Roll-off) The low frequency audio roll-off is adjustable to optimize performance for ambient noise conditions or personal preference. Low frequency audio content may be desirable or distracting, so the point at which the roll-off takes place can be set to 20, 35, 50, 70, 100, 120 or 150 Hz. Rolloff 70 Hz Phase (Selecting Audio Polarity) This setting allows for configuration for use with certain microphones, or for setting custom parameters.

Requires a receiver with this function enabled. ProgSw Power Use the and arrow buttons to select the desired function or disable the switch NOTE: The programmable switch will continue to operate whether or not settings are locked. Selecting Battery Type The voltage drop over the life of batteries varies by type and brand. Be sure to set the correct battery type for accurate indications and warnings. The menu offers alkaline or lithium types. B a t Ty p e Alk. Lith. If you are using rechargeable batteries, it is better to use the timer function on the receiver to monitor the battery life rather than the indicators on the transmitter. Rechargeable batteries maintain a fairly constant voltage across the operating time on each charge and stop working abruptly, so you will have little or no warning as they reach the end of operation. Remote Remote control "dweedle" tones from a smart phone can be used to control the transmitter. This setting Enables or Disables it. Locked? The settings can be locked to prevent inadvertent changes being made. www.lectrosonics.com 13 Locked? Ye s No Gain 25 -40 -20 0 A small padlock symbol will appear on adjustment screens when changes have been locked. When settings are locked, several controls and actions can still be used: · Settings can still be unlocked · Menus can still be browsed · Programmable switch still works (Mute, Talkback and On/Off) · Power can be turned off by using the programable switch if in Power mode or by removing the batteries.
