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. Channel setting (1
–17):
Confirm the channel number on the transmitter matches the number on the receiver (s).
To adjust the channel number, 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. The
transmitter is now programmed to your desired channel.
6. Audio Mute:
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. Gain Setting:
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. To adjust the gain setting, turn the transmitter ON; open the battery
door, press and hold the “Lock” button till the Lock icon disappears from the LCD display; press the “Set” button
to scroll through and select 1 for microphone or 2 for line level audio.
8. 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.
