(Continued)
Since the entertainment audio input is not controlled by a switch,
there is no way to deselect the entertainment source except to
disconnect the source at the audio input connector. In the event of a
high pilot workload and/or heavy traffic, it is wise to disable the
entertainment audio to eliminate a source of distraction for the flight
crew.
NOTE
• Passenger briefing should specify that AUX AUDIO
IN (entertainment audio input) and Portable
Electronic Device (PED) use is permitted only
during the enroute phase of flight.
• Disconnect the cable from the AUX AUDIO IN jack
when not in use.
r-' •
Use caution with audio cables in the cabin to avoid
entangling occupants or cabin furnishings and to
prevent damage to cables.
