This section defines each control of the transceiver. See Figure 4 for
location of controls. For detailed operating instructions refer to chapter

9.1 CONTROLS AND CONNECTIONS
VOLUME CONTROL (VOL/PWR)
Adjusting this control clockwise, increases the audio volume level.
Secondary Use
When in PA or Fog mode, controls the listen back volume.
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 does.
This point is called the squelch threshold. Further adjustment of the squelch
control will degrade reception of wanted transmissions.
MIC Connector
Connects to the supplied noise canceling speaker microphone.
