SPKR/PA (SPEAKER/PASSENGER ADDRESS) SWITCH

The SPKR/PA switch has three functions:

•Speaker ON

•Speaker OFF

•Passenger address system ON.

The SPKR/PA rocker switch can be pushed to the left or right. Each time the right side of the switch is pushed, the mode changes from left to right as indicated by the light emitting diodes (LEDs) and does not wrap around. Each time the left side of the switch is pushed, the mode changes from right to left as indicated by the LEDs and does not wrap around.

Pushing the SPKR/PA switch toggles between the following selections:

•ON - The ON light is illuminated, all selected audio will come over the cockpit speaker (headset audio is always on).

•OFF - The OFF light is illuminated, no audio is available over the cockpit speaker (headset audio is always on).

•PA - The PA light is illuminated; the pilot can transmit through the microphone to the passenger cabin speaker. The normal microphone push-to-talk (PTT) switch is used for the PA function. The copilot can continue to use the selected COM radio while the pilot is heard over the speaker. The pilot’s microphone has priority if both the pilot and copilot PTT switches are pressed at the same time and both audio pan- els are on PA.

COM MIC (MICROPHONE) SELECTOR BUTTONS
