Unit power is turned on and off by pushing the volume knob. In the
OFF
or
"

" position, the pilot is connected directly to Com 1. This allows com-
munication capability regardless of unit condition. Any time power is re-
moved or turned

mode.
The power switch also controls the audio selector panel functions, inter-
com, and marker beacon receiver. Unless the mic selector is in Com 3
mode, at least one of the selected audio LEDs will be on (Com 1 or Com
2).
