Adjustment range: 5 to 25 dBV, adjustable in 2-dB steps, can be switched off The squelch eliminates annoying noise when the transmitter is switched off or when there is no longer sufficient transmitter power received by the receiver. If you switch the squelch off or adjust the squelch threshold to a very low value, loud hissing noise can occur in the receiver. Before adjusting the squelch threshold, set the volume of the headphone output PHONES to the minimum (see page 13). Adjust the squelch threshold with the transmitter switched off to the lowest possible setting that suppresses hissing noise. A high squelch threshold reduces the transmission range.
The squelch should only be switched off for servicing purposes. With the squelch threshold set to "5 dB", you switch the squelch off by keeping the DOWN rocker button pressed for 3 seconds.
