The NAV RX audio select switches (blue switch bats) are three-position switches. When
set to the up or down position, the respective NAV RX audio is selected on. When set to
the center off position, the respective NAV RX audio is selected off.
The master RX volume control ( RX VOL ) adjusts all RX audio concurrently from 1% to
full. It is important to set the individual radio volume controls to a nominal level, and
then use the master
RX VOL control on the audio controller to adjust for changing flight
conditions.
When the red mode switch is set to NORMAL, the passengers will hear the radio audio
as selected on the controller. The passengers will not hear any radio audio when the
red mode switch is in the ISO/EMR position.
3.3.2 Transmit Selector Switch
TX Indicator Transmit Selector
Switch
The TX selector switch is a six-position switch used to select the desired transceiver.
When rotated fully clockwise, this switch selects the PA function. When the hand mic or
TX PTT switch is activated, the mic will be coupled to the radio (or PA) selected. The
pilot has priority over the copilot during TX operations.
RX audio for the transceiver selected is automatically activated as a function of the
rotary selector switch, and no additional switching is needed to establish outside
communication. During TX, all audio selected is muted except the sidetone of the
transceiver in use.
The front panel TX indicator will illuminate green when either the pilot or co-pilot
transmits. It will not light when the hand mic is used.
