3.2 Power and Fail Safe (1)
Unit power is turned on and off by pushing the volume (left) knob. In the
OFF
or "EMG" position, the
pilot headset is connected directly to Com 1 as well as unswitched input #1. This allows communication
capability regardless of unit condition. Any time power is removed or turned
OFF
, the audio selector por-
tion will revert to fail-safe mode.
The power switch controls all audio selector panel functions and the intercom. All pushbutton selections
and menu modes (except Bluetooth telephone association) will be remembered and return to the last state
when turned on.
3.2.1
ICS and Music Volume Controls (1)
The inner knob (ICS) controls the volume of the intercom audio. It does not affect the radio, telephone, or
music volume.
The outer knob (♫) controls the volume of the Music 1 input (and Bluetooth music). It has no effect on the
radio, intercom, telephone, or Music 2 input for the passengers.
Adjust the radios and intercom volume for a comfortable listening level. Most general aviation headsets
today have built-in volume controls; therefore, volume also can be further adjusted at the individual head-
set.
3.2.2
M760REM Radio power (as COM 1)
The power supply for the M760REM communication transceiver is separate from the audio panel power
and control. When the M760REM is installed as COM 1, or as a stand-alone COM, it can be controlled
