Adjusting the squelch threshold

Interference of the RF signal due to other transmission links can be eliminated as follows:

Switch the transmitter off. The receiver should no longer receive a signal.
If the receiver still receives a signal, use the rotary switch for squelch threshold "SQ" to increase the squelch threshold so that the signal will no longer be received. If the signal cannot be eliminated in this way, set the transmitter and the receiver to a different channel.
Switch the transmitter on again and check if the receiver receives the transmitter signal.

If the squelch threshold is adjusted too high, the transmission range will be reduced. Therefore, always adjust the squelch threshold to the lowest possible setting.
