PXE7300 Series IFE System Installation and Operator’s Manual
After wiring is complete, verify power is ONLY on pin 21 of the connector, and airframe ground on bot- tom connector pin 22. Failure to do so will cause serious internal damage and void PS Engineering's war- ranty.
To install the PXE7300, gently slide the unit into the mounting rack until the hold-down screw is engaged. While applying gentle pressure to the face of the unit, tighten the 3/32" hex-head in the unit until it is se- cure. DO NOT OVER TIGHTEN.
: Do not over-tighten the lock down screw while installing the unit in tray.
Insert disc, and verify that the player accepts the disk with about ½ of the diameter in the unit. The player should pull the disk smoothly and drop into place.
The player will begin to play, automatically about 20 seconds (after reading the disc).
If the unit is in disc mode, with CD inside at power-up, it will play (after reading the disc).
Verify that all Disc modes operate.
Push the “Eject” button and verify that the disc is ejected within about 10 seconds.
Verify radio operation on AM and FM
Verify that aux audio is presented to the output (if connected).
Evaluate the audio interface to be certain that the IFE audio is muted during intercom and radio com- munication.
If muting override is provided, evaluate the switch location and verify operation.
Evaluate the audio performance
Evaluate the audio level to verify that the music is adequate under flight conditions.
Evaluate the muting system to demonstrate that the music will be adequately muted if de- sired, by radio and intercom.
Evaluate the muting override control if equipped.
Evaluate failure remediation from crewmember location
Turn unit off
Locate and pull unit circuit breaker
With the disc playing, with minimum volume, listen to the following audio sources (as equipped), adjusted to normal listening level:
Comm 1, comm. 2, comm 3, HF
Nav 1, Nav 2
ADF (1 and 2)
DME (1 and 2)
Any other audio sources
Select FM Mode, and repeat step 6, listening for interference on the aircraft audio sources. Pay par- ticular attention to the frequencies listed in table.
Select AM Mode, and repeat step 6, listening for interference on the aircraft audio sources.
Select COM 1 for transmit. Tune COM 1 to 118.00, and the PXE7300 to 107.3 MHz. Transmit a test
count and evaluate the unit display and audio output for inconsistencies
