Operating the internal disc Player
The single-disk CD player is designed for simple operation. There are five buttons with the following func-
tions.
►
(Play) Plays disc, push again to pause
►►
(Jump Forward) Push to jump to the next track, hold to fast forward in current track
◄◄
(Jump Backward) Push to jump to the previous track, hold to rewind in current track
(Stop) Stops playback
▲
(Eject) Ejects disc
The CD player will begin to play automatically when a CD is inserted. Press the play button to pause the
track.
The jump forward button advances to the next track. Jump backwards selects the previous track.
On MP3 units (11954, 11956, 11957, 11958), pressing the Jump Forward and Jump Backward buttons at
the same time will toggle the unit into a random play mode. Random Mode is particularly useful if the disc
contains a large number of files.
Stop ceases play, and Eject removes the disk from the CD player.

Internal Recorder System (Optional)
The Intercom Recording System (referred to here as the IRS) is a digital recording system allowing auto-
matic storage and immediate playback of all incoming aircraft radio receptions.
Operating as a continuous loop recorder, (first message received will be the last heard), the recorder has
one minute of recording time divided into as many as 16 messages. With its own built-in VOX circuit,
there are no buttons to press to start recording. The system automatically begins to record the instant the
radio becomes active. Only aircraft radio audio in pilot’s headset is recorded and only the pilot will hear
the playback audio, in one ear.
3.5.1 Operation
Recording is automatic; there is no action required by the pilot. To play back the last recorded message,
simply press the momentary switch associated with the IRS. Each additional press of the button will play
the preceding recorded message.
To stop playback, hold the playback button for two seconds. The next push will then play the prior mes-
sage.
