Adjusting the squelch
Squelch is a function of the receiver that passes audio when the desired radio signal is
above the squelch threshold and mutes audio when the radio signal is below the threshold.
The higher the squelch setting, the stronger the incoming signal will have to be in order for
you to hear it.
To set your squelch level, place the wireless transmitter at the furthest distance you expect
to use it and adjust the squelch level until it mutes the signal. Then adjust the squelch level
back up until the wireless transmitter signal is heard.
The squelch level should be set just above the
background radio signal noise. If the squelch
setting is set too low, you will hear static noise
pass through the receiver when the transmitter
is turned off or out of range.
11. Short press the SET (3) button two times
to enter the squelch adjustment mode.
12. Press the UP (1) button to increase the
squelch threshold level.
13. Press the DOWN (2) button to decrease
the squelch threshold level.
