7 CONTROLS AND INDICATORS
NOTE
This section defines each control of the transceiver. See Figure 4 for
location of controls. For detailed operating instructions refer to chapter 8
of this manual.
VOLUME CONTROL
(

)
Adjusting this control clockwise, increases the audio volume level.
SQUELCH CONTROL

Adjusting this control clockwise, sets the point at which random noise on
the channel does not activate the audio circuits but a received signal does.
This point is called the squelch threshold. Further adjustment of the squelch
control will degrade reception of wanted transmissions.
