3.3 Power Switch (3) (EMG-Fail Safe Operation)

Unit power is turned on and off by pushing the center (pilot) volume knob. The power

switch controls the audio selector panel functions and intercom.

3.3.1 Single Panel Fail Safe Operation

In the OFF or "EMG" position, the pilot is connected directly to Com 1. This allows

communication capability regardless of unit condition. Any time power is removed or

turned OFF, the audio selector will be placed in the fail-safe mode.

3.3.2 Dual Panel Fail Safe Operation

In a dual installation, the PAC24 designated as Pilot’s at installation, will default to

Com 1. The audio panel designated as copilot will not operate in the off position. This

prevents compromising the pilot’s audio capability in the event of a dual audio panel
