Local oscillators and internal signals from entertainment equipment can cause undesired interference with
other aircraft systems. Before takeoff, operate the entertainment devices to determine if there is any adverse
effect within the aircraft systems. If any unusual operation is noted in flight, immediately switch off the
entertainment devices.
All entertainment devices must be switched off for both takeoff and landing.
2.7.2.1
Music 2 Mute (J2 Pin 13 & 14)
Connecting J2 pin 13 to pin 14 (or ground) through a SPST switch places the music #2 music source into
the Karaoke Mode. In this mode, incoming music and intercom conversation will not mute the music for
the passengers’ intercom net. This allows uninterrupted music during casual conversation.
