3.10 Post-Installation Test
Check all entertainment units for proper RS-485 data bus connections.
Ensure the Audio/Video Distribution Unit is interfaced with the data bus.
All control units that are installed in the aircraft should be tested for proper
operation (i.e. Switch Panels, Hand-Held Remote Controls, and Touch
Screen LCD Monitors). Use one (1) of these control units to activate an
entertainment audio function. Ensure entertainment audio is present in
the speakers and headphones. Activate the audio briefer, and ensure that
the briefer overrides the entertainment audio. Now key and speak into a
microphone to verify that the PA audio overrides the briefer and
entertainment audio.
All aircraft audio and video functions should be tested for proper
operation. If all audio and video functions are operational, the
Audio/Video Distribution Unit has been properly installed. Refer to Section
6.0, Troubleshooting, if the audio or video selection is not functioning
properly.

will depend on how many entertainment units are installed in the aircraft.

All audio and video sources that interface with this master control unit
must be checked for proper operation. Use the switch panel controls,
hand-held remote controls, or touch screen monitor to verify that
entertainment units are operating in a proper manner. Activate the briefer
and ensure audio is present in the speakers and headphones. Key and
speak into a microphone and verify that PA audio is present in the
speakers and headphones. If a video briefer is installed, ensure that the
entertainment video outputs are overridden when the video briefer is
activated. Refer to Section 6.0, Troubleshooting, if audio or video
functions are not operating properly.
