PLAYING A CD

1.  Set HOLD to OFF.

2.  Open the disc compartment.  Then handling the CD by its edges,
    carefully place it, label side up, over the compartment's center hub.
    Press gently on the CD's center so the CD lies flat in the compartment.
    Then close the compartment cover.

3.  Press PLAY/PAUSE.  The CD player automatically turns on, 00 flashes on
    the display, then Track 1 begins to play.  The display shows the 
    current track number.

    To display the current track's elapsed time, hold down MEMORY/E-BASS
    until the elapsed time appears.  To return to the current track number,
    hold down MEMORY/E-BASS again until the current track number appears.

4.  Adjust the volume to a comfortable listening level.

    If you connected headphones, amplified speakers, or a CD-to-cassette
    adapter to the CD player's PHONES jack, set VOLUME on the CD player to
    the desired level.

    If you connected the CD player's LINE OUT jack to your home audio
    system or your car's stereo, use the volume controls on those systems
    to set the desired volume level.

    To enhance the bass sound, briefly press MEMORY/E-BASS.  BASS appears.
    To return to normal sound, press MEMORY/E-BASS again.  BASS disappears.

5.  When the last track finishes playing, the display alternately shows the
    total number of tracks and total playing time of the CD for about 2
    minutes, then the CD player automatically turns off.  To stop play and
    turn off the CD player sooner, press STOP/CLEAR twice.

Notes:

     E-Bass turns off when the CD player is turned off.

If you press STOP during play, the CD player exits INTRO, RANDOM, and 
REPEAT play.

6.  To remove the CD, press the eject button to open the disc compartment.
    Be sure the CD has stopped spinning, then press the tab in the center
    of the disc compartment's center hub and lift the CD.  Then close the
    compartment cover.

DIGITAL ANTI-SHOCK SYSTEM (DASı) (CD-3640 ONLY)

Your CD-3640 contains special circuits to overcome sound skipping problems
caused by shock or vibration.  This means you can carry the CD player
anywhere you go or use it in your vehicle.  When you turn on the anti-shock
system, the CD player continuously saves the next few seconds of music in
memory.  During a shock or vibration that would normally make a track skip
or pause, the CD player plays directly from memory.

To turn on the anti-shock system, set DAS on the left side of the CD
player to IN.  If the CD player is playing a CD, the sound briefly stops
and DAS appears.

To turn off the anti-shock system, set DAS to OUT.  The sound briefly stops
and DAS disappears.

Note:  The CD player consumes additional battery power when you use the
       anti-shock system.  When you use the CD player in a stable location
       turn off the system to conserve battery power.

LOCKING THE CONTROLS

To prevent accidentally turning the CD player on or off, or changing the
track you are listening to, slide HOLD to ON.  No controls work except
eject, VOLUME, DAS (CD-3460 only), and HOLD.

Slide HOLD to OFF to operate the controls again.

AUDIBLE SEARCH

Use audible search during play to rapidly search forward or backward for a
specific section of a track.  During audible search, the CD plays at a 
lower volume and a higher speed.  The current track's elapsed time appears
on the display.

To search forward, hold down fast forward (right arrow) (>).  To search 
backward, hold down rewind (arrow left) (<).  To resume normal play, 
release the control.

AUTOMATIC SEARCH MUSIC SYSTEM (ASMS)

You can use ASMS before or during regular or programmed play to quickly
locate any track on a CD.

While the CD is stopped, repeatedly press rewind or fast-forward to move
backward or forward to the desired track.  Press PLAY/PAUSE to play the
track.

During play, press rewind to return to the beginning of the current track.
Press rewind again to return to the beginning of the previous track.  To
move to the beginning of the next track, press fast-forward.

PAUSE AND CUE

To temporarily pause play, press PLAY/PAUSE.  Arrow right (>) flashes on the
display.  Press PLAY/PAUSE again to resume play.

You can also use PLAY/PAUSE to select (cue) a track before playing.  When
the CD player is stopped, press fast-forward or rewind to select the track
you want to cue.  Then press PLAY/PAUSE twice.  Arrow right (>) flashes.

To cue a track in a programmed sequence, press PLAY/PAUSE to pause the CD.
Arrow right (>) flashes.  Then press rewind or fast-forward to display the
track you want to cue.

To play the cued track, press PLAY/PAUSE.

INTRO SCAN

The intro scan feature automatically plays the first 10 seconds of each
track on a CD.

During play, repeatedly press PLAY MODE until INTRO appears on the display.
Intro scan starts from the first track.

To return to normal play, press PLAY MODE so INTRO disappears from the
display.  The CD player resumes normal play.

Notes:  Intro scan plays the tracks in the programmed order if you have
        programmed a sequence.

        You can use rewind or fast-forward to skip through the tracks.

REPEAT PLAY

Your CD player can repeatedly play a single track, the entire CD, or a
programmed sequence.

To repeat a single track, before or during play, repeatedly press PLAY
MODE until (loop symbol) 1 appears.  At the end of the track, the CD player
repeatedly plays it.

To repeat an entire CD or a series of programmed tracks, before or during
play, repeatedly press PLAY MODE until (loop symbol) ALL appears.  When 
the CD player reaches the end of the CD or the programmed sequence, it 
returns to the first track and continuously replays all the tracks.

To cancel repeat play, repeatedly press PLAY MODE until (loop symbol) 1
and (loop symbol) ALL disappear.

RANDOM PLAY

In random play, the CD player plays all the tracks once in random order,
then automatically stops.  To start random play at any time, repeatedly
press PLAY MODE until RANDOM appears.

Note:  If you select random play during programmed play, the CD player
       stops the programmed sequence and starts random play of all tracks.

       To cancel random play, press PLAY MODE so RANDOM disappears.

PROGRAMMED PLAY

You can program up to 24 tracks on a CD to play in any order you choose,
and you can program the same track to play more than once.

Follow these steps to program and play a sequence.

2.  Hold down MEMORY/E-BASS until the selection number (01) and the track
    number (00) appear as PGM flashes.

3.  Repeatedly press either fast-forward or rewind to display the number of
    the first track you want to program.

    number advances by one and the track number on the display returns to
    00.

    tracks.

6.  To play the programmed sequence, press PLAY/PAUSE.  PGM appears and the
    first track in the sequence plays.

    to move forward or backward in the sequence.

    stop the CD before the end of the sequence, press STOP/CLEAR.

    To replay the programmed sequence, press PLAY/PAUSE within 2 minutes.

    in the sequence.

    To add to the end of a programmed sequence, hold down MEMORY/E-BASS 
    until the first programmed track appears, then repeatedly press
    MEMORY/E-BASS (within 2 minutes) until track number 00 appears.  Then
