3.9.1 Transmit
Selectors
The transmit selector controls are six position rotary switches, one on each side of the panel to
correspond to the user on that side of the aircraft. The controls select the transmit function required by
the relevant user. Each rotary selector switch is completely independent of the other, and the pilot and
copilot have equal priority during transmit. When the PTT is activated, all audio selected on the side of
the controller that is transmitting is muted, except the sidetone of the transceiver in use.
3.9.1.1
Automatic Receive Audio
Receive audio is automatically selected as a function of the respective rotary selector switch. No
additional switching is needed to establish external communication.
3.9.1.2
Transmit Annunciator
During transmit from either the pilot or copilot position, the appropriate TX annunciator (green) will light on
the front panel.
