Installation Instructions
All cabin entertainment equipment, such as the FD900X3B Ver B, should be installed on a
non-essential bus and have a dedicated circuit breaker. It is a requirement that a switch be
installed in the cockpit so that the pilot can de-energize the entertainment system should it
become necessary.
There are two #8 mounting holes located on the ends of the housing. It is sufficient to
mount by the two attach points. Mounting locations in the cabin can be anywhere that is not
blocked or enclosed by metal surfaces. A drawer, cabinet, headliner or other suitable
location is fine.
When using the headsets, it is necessary to cycle the headset to get the frequency’s to
tune. Sometimes if the operator leaves his/her hands touching the headset the arms and
body will act like an antenna and the tuning is more difficult. For optimum tuning, press the
TUNE button and release.
It is important to match the output impedance of the audio sources. The input of the
FD900X3B should be low level audio such as that used for the inputs to home or
automotive entertainment systems. If one source is significantly stronger than another, it
will cause significant variation in the volume levels between channels. It may also cause
frequency bleeding and crossover between the audio channels.
Power
The FD900X3 Ver B is a 28VDC device that requires 0.1 Amps of power to operate.

Audio Wiring Suggestions
The center conductor of coaxial cable should be high, and outer shield should be the
return/low.
Avoid routing audio wiring parallel to:
•AC wiring
•Strobe wiring
•DC motor supply cables
•Inverter cabling
•Or any other potential noise source.
Wiring
Recommended cable for audio purposes is PIC 75 Ohm Coax, P/N V75268. This is a
lightweight, flexible, and low signal loss cable which meets FAA flammability requirements
of FAR 23.1359(d), FAR 25.853(a) and FAR 25.869(a)(4).
Similar aviation coaxial cable can be used from other vendors, as well.

Operation Instructions
The passengers will be able to access the different audio channels by momentarily
pressing the TUNE button found on the headset (not supplied). It is necessary to cycle the
headset through the different frequencies once turned on so that it may recognize the
transmitting frequencies.
If you recognize degradation in the quality of your audio or that you cannot channelize the
frequencies, check to make sure your headset batteries have sufficient power.
