3.3.1 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.

3.3.1.1 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.

3.3.1.2 Transmit Annunciators

During transmit from either the pilot or copilot position, the appropriate TX annunciator (green) will light on

the front panel.

3.3.1.3 TX Selector Example

In the figure above, the positions of the rotary selector switches indicate that the right side of the controller is

set for transmit and receive operation on the COM2 transceiver while the left side of the controller is set for

transmit and receive operation on the FM1 transceiver.

3.3.2 Hand Microphone

The hand mic functions without power and will work in emergency or equipment failure situations. The hand

mic normally functions on the left side of the controller but can be connected to the right side at the time of

installation by changing an internal switch. When the hand mic or transmit PTT switch is activated, the mic

involved will be coupled to the radio (or PA) selected. The TX annunciator will not light when the hand mic is

used.
