OPERATING INSTRUCTIONS
1. Before installing batteries, determine if they are carbon zinc, heavy duty, alkaline or rechargeable. Open the
battery compartment door and locate the “ALK/NiMH” switch. If using carbon zinc, heavy duty or alkaline
batteries slide the switch to the “ALK” position; if using NiMH rechargeable batteries slide the switch to the
“NiMH” position.
2. Install (2) AA style batteries by pressing them into place, observing the proper battery polarity. Incorrect insertion
may cause both mechanical and electrical damage not covered by the limited lifetime warranty. Units will not
work if the batteries are incorrectly installed.
3. Plug the microphone into the 3.5mm audio input jack located on the left side of the transmitter housing. The
microphone cable is the transmitter antenna. Do not bunch up the cord, wrap it tightly around your body or wrap
it around the transmitter. For maximum range, the cord should hang loosely from the microphone to the
transmitter. Use only Talk & Listen approved microphones, substitutions can greatly affect the overall
performance therefore causing poor audio quality or reduced transmission range between the transmitter and
receiver(s).
4. Turn the power switch on top of the transmitter to “ON”. The LCD backlight will appear and stay on until it detects
10 seconds of inactivity, it will then automatically shut off to save battery power. The LCD backlight will
automatically turn back on once any of the control buttons are pressed.
5. Confirm the channel number on the transmitter matches the number on the receiver (s). To adjust the channel
number, locate the “LOCK” button, press and hold it for three seconds to unlock the transmitter. The ”lock” icon
on the LCD display will disappear once the unit is unlocked. Use the “+” and “-“buttons on the front panel to scroll
through the channels and choose the appropriate channel. After 10 seconds of inactivity the transmitter will
automatically lock and the “LOCK” icon will reappear on the display.
6. To temporarily silence during use, press and hold the “-” button until the “Gain Indicator” (number on the right of
the screen under the LCD display) starts to flash, this indicates the audio has been muted. Repeat the process
to restore the audio signal. The “Gain Indicator” icon will stop flashing.
7. When using the line input for auxiliary equipment (such as CD player or iPOD™), turn the “Gain Control” to “1”;
higher levels will distort audio.
8. Transmitter GRP 1 Programming: turn the transmitter OFF; open the battery door, press and hold the “Lock”
and “Set” buttons simultaneously while turning the transmitter power ON, the green backlight on the LCD display
will illuminate showing the current channel number programmed; press the “-” or “+” buttons to scroll through and
select one of the 17 available channels. When finished, close the battery door and turn the transmitter OFF to
exit programming mode.
9. Transmitter GRP 9 Programming: turn the transmitter OFF; open the battery door, press and hold the “Lock”
and “Set” buttons simultaneously while turning the transmitter power ON, the green backlight on the LCD display
will illuminate showing from left to right, the current “group ” and “channel” numbers. Press the “-” or “+” buttons
to scroll through and select up to 8 of the 17 available channels, press the “set” button to activate or deactivate
any channel. When the “memo” icon is displayed above the channel number, the channel is activated; when the
“memo” icon is not displayed above the channel number, the channel is deactivated. When finished, close the
battery door and turn the transmitter OFF to exit programming mode.
10. RF Level Adjustment: turn the transmitter off; open the battery door, press and hold the “Set” button and
simultaneously turn the transmitter ON to enter into the RF Level Programming mode. There are 5 individual RF
level settings. The signal meter icon on the LCD display is used to indicate the current programmed RF level.
Settings are -1dBm (no signal bar-lowest setting); +3dBm (1 signal bar); +7dBm (2 signal bars); +11dBm (3
signal bars); and +15dBm (4 signal bars-the highest RF Level Setting). Press the “SET” button to scroll through
and select the RF level setting. When finished, close the battery door and turn the transmitter OFF to exit
programming mode.
11. When finished using Transmitter, make sure to power off.
