9 CONTROLS
AND
INDICATORS
NOTE
This section defines each control of the transceiver. See Figures for location of controls.
For detailed operating instructions refer to section “8 BASIC OPERATION.”
POWER SWITCH / VOLUME CONTROL (VOL/PWR)
Turns the transceiver on and off as well as adjusts the audio volume.
Press and hold this knob for one second to turn the radio on. Clockwise rotation of
this knob increases the audio volume level.
Press and hold this knob for two seconds to turn the radio off.
SQUELCH CONTROL (SQL)
Adjusting this control clockwise sets the point at which random noise on the
channel does not activate the audio circuits but a received signal will. This point is
called the squelch threshold. Further adjustment of the squelch control will degrade
reception of wanted transmissions.
