Pre-recorded File Playback (Option 1 ONLY)
The PXE7300 is designed to play up to five special files on a recorded MP3 disc. This can be used for pas-
senger briefing, tour narration, or other in flight uses.
When one of the five inputs is triggered, a corresponding file on a specially encoded disc will start to play,
regardless of the mode in use.
When the file has completed play, the unit will return to the previous mode and track, but it will be paused.
The special disc must be labeled as the volume 7300, and the tracks 0001.MP3 through 0005.MP3. Other
files, such as music, can be stored on this disc. The normal files will play, but files with the filename
0001.MP3 through 0005.MP3 will not play unless the respective input is activated, OR specifically se-
lected from the front panel. This section can be used to test the disc and determine which files are stored.
See Appendix A for details on storing MP3 files.

justed by the aircraft dimmer circuit.
