Set the volume to a low level before putting the headphones on Do not continuously expose yourself to high volumes. 1. When one of the standard displays is shown on the display panel: Press the rocker button to adjust the volume at the headphone output (PHONES).

Danger of hearing damage!If you switch the squelch off or adjust the squelch threshold to a very low value, loud hissing noise can occur in the receiver. The hissing noise can be loud enough to cause hearing damage!Always make sure that the squelch is switched on. Before adjusting the squelch threshold, set the volume of the headphone output PHONES to the minimum (see page 21). Never change the squelch threshold during a live transmission. 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. The dotted line goes off and the audio level display "AF" shows full deflection (hissing noise). displays the squelch 823. 925 MHz **2000** RF AF P MUTE 823. 925 MHz **2000** RF AF P If you have accidentally switched off the squelch: Press the UP rocker button to switch the squelch on.
