tooth® music streaming (which is presented as Music 1). Entertainment input number 1 is J2 pins 23 (left
channel) and 24 (right channel), with respect to pin 25, and Entertainment number 2 is connected to 26

2.7.1.1 Music 1 all headsets (J2, Pin 22)
If J2, Pin 22 is connected to aircraft ground, Music 1 will also be heard in the passengers’ headsets. Music
2 will be disabled when J2, Pin 22 is grounded.
2.7.2 Entertainment muting
The PAR100EX-system incorporates a "Soft Mute™" system. This will mute the entertainment devices
during intercom conversation or radio reception. The four muting modes are controlled by the front panel
“Mute” button. See §3.9 for more information.
CAUTION
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 ad-
verse 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 Entertainment 2 Mute (J2 Pin 13 & 14)
Connecting J2 pin 13 to pin 14 (or ground) through a SPST switch places the entertainment #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.
2.8 Disassembly
Remove the top cover, by removing four (4) or five (5) Phillips head screws from the PAR100EX top.
NOTE: THE SCREW IN THE REAR OF THE PANEL (if present) IS A DIFFERENT LENGTH
THAN THE OTHER FOUR. YOU MUST PUT THIS SHORTER LENGTH SCREW BACK IN
THE SAME LOCATION OR DAMAGE WILL OCCUR. See Figure #2-2.
There is a spacer on the screw on the front right corner that will fall out. Save and retain for later.
