ON-OFF/Volume - Turning the knob clockwise turns power on and sets the volume level.
Turning it counterclockwise to the detent turns power off. The minimum volume level can
be set by programming. Soft power down can be programmed as described in Section
3.1.2, and the volume control can be disabled as described in Section 3.1.3.
Channel Switch - This 16-position switch selects up to 16 channels in the current zone.
Additional zones can be programmed to allow up to 864 channels to be selected by this
switch. This control can be disabled as described in Section 3.3.
Rotary Option Switch - This is a three-position switch that can be programmed to control
various options. The “A” position is “on” and the “B” and “C” positions are “off” (see
Section 4.1). When this switch is programmed to select zones, “A” selects Zone 1, “B”
Zone 2, and “C” Zone 3 if applicable.
Antenna Connector - This is the connection point for the antenna. Make sure the antenna
is tight before using the radio.
