POWER SWITCH/VOLUME CONTROL
Turns the transceiver on and off, and adjusts the volume.

SQUELCH CONTROL
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 degrades reception of wanted transmissions.

number. When held down, channels increase continuously.
