When in the PA or Fog mode, turning this knob changes the output vol-
ume of the connected horn speaker.
PWR/VOL Knob

Turns the transceiver on and off as well as adjusts the speaker volume.
To turn the transceiver on, press and hold this knob until the radio turns on.
When the power is turned on, the transceiver is set to the last selected
channel. Clockwise rotation of this knob increases the internal and speaker
microphone volume.

SQL Knob
(Squelch Control)

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.
