PWR/VOL knob in counter clockwise rotation until a beep is heard. All
icons and frequencies disappear from the display.

volume by PWR/VOL knob, you can directly hear a background noise wi-
thout waiting to receive any signals. If you press the PTT key, the squelch

ting indicator lights up red while the PTT key is pressed.

ception won’t sound clear.
