3. Verify that each installed transceiver keys for transmission and transmits clear audio

from the pilot's mic when selected for transmission and the Pilot PTT key is pressed.

(Because the audio panel can be configured to simulate received sidetone internally,

verifying transmission with a separate radio not in the system is recommended.)

Depending on configuration and sometimes COM system wiring, other

transceivers may be muted during transmit. Also, the audio panel may mute

the speaker during PTT.

4. Move the headset to the copilot's headset jacks and verify that any one of the

installed transceivers (testing each is not necessary) receives and transmits copilot

mic properly as above.

3.8.3 Verify Audio from Installed Receiver and Alert Sources

1. Connect a headset to the pilot's headset output and mic input jack (depending on

configuration and ICS mode, copilot or passenger positions may not hear all of these

sources).

2. Verify each installed receiver (NAV/ADF/DME) can be heard when selected (use test

signal generators/transmitters when necessary).

3. Verify each installed unswitched (alert) source can be heard when the source is

instructed to play a simulated alert/message.

3.8.4 Verify Speaker Output (if installed)

1. Select the speaker output and verify any one transceiver or receiver is heard clearly.

2. Verify that any one unswitched (alert) source is heard clearly in the speaker

(depending on configuration, these may be heard in the speaker regardless of speaker

selection).

3. Initiate PA (Passenger Address) mode and verify that from both the pilot and copilot

position the crew position that is pressing PTT has their mic delivered to the speaker

clearly.

If a loud squeal is heard while testing PA, it is because there is too much

acoustic feedback between the speaker and the mic. If they cannot be placed

further apart, a lower volume configuration should be used.

installations, there is insufficient distance between the speaker and crew seat

positions for PA to speaker to reliably operate. In these conditions, the "PA to

speaker" volume can be set very low and PA audio will still be delivered to

the headsets.
