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. 20 Adjusting settings via the operating menu Display Squelch is . . .
