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. 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 headphone/earphone into the 3.5mm audio output jack located on the left side of the receiver housing.
The headphone/earphone cable acts as the receiver antenna. Do not bunch up the cord, wrap it tightly around
your body or wrap it around the receiver housing. For maximum range, the cord should hang loosely from the
headphone/earphone to the receiver. Use only Talk & Listen® approved headphones/earphones, substitutions
can greatly affect the overall performance and cause poor audio quality or reduced transmission range between
the transmitter and receiver(s).
4.
Turn the power switch on top of the Receiver 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 come back on once any of the control buttons are pressed again.
5.
The headphone/earphone volume level on the receiver automatically defaults to “3” at start up to protect the user
fr
om accidental ear damage. To view and adjust the volume level press the “+” or “-“buttons on the front panel,
the LCD backlight will automatically light up and the volume setting number will appear on the LCD display. To
adjust the volume level use the “+” or “-“buttons to set at an appropriate listening level. Once the receiver
detects 10 seconds of inactivity, the backlight will automatically shut off and the volume level icon will disappear
to save on battery power.
6. Confirm the channel number on the receiver(s) is the same as the transmitter channel; to adjust the channel
open the battery compartment door, locate the
“LOCK” button, press and hold for three seconds to unlock the
receiver. The
“lock” icon on the LCD display will disappear indicating the unit is now unlocked for programming.
Using the
“+”or “-“ buttons on the front panel to scroll through the available channels, select the channel. After
10 seconds on inactivity the receiver will automatically lock and the
“LOCK” icon will reappear on the LCD
display and the LCD backlight will shut off.
7. The adjustable Squelch feature allows the user to adjust the receiver circuit to turn off the audio input to the
headphone/earphone when the signal is weaker than the noise it is receiving or there is no radio signal at all:
both of which cause an annoying noise. The factory pre-
set setting of “3” will work for most environments. To
determine the squelch setting, open the battery compartment door and locate the “SET” button, press once and
the “SQL” code will appear on the LCD display for 5 seconds and then disappear. To adjust the Squelch setting,
open the battery compartment door, press both the “LOCK” and “SET” buttons simultaneously for 4-5 seconds,
the “SQL” code will appear; use the “+” or “-“ buttons on the front panel to adjust. After 10 seconds of inactivity,
the Receiver will automatically lock; the “LOCK” icon will reappear on the LCD Display and the “SQL” code will
disappear and the LCD backlight will shut off.
