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.

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.
