select the proper track, and then push the PLAY/PAUSE (13) button
so the unit goes into play mode (the play/pause LED will glow). Listen
to the CD and when the CD gets to the approximate spot, push the
PLAY/PAUSE (13) button so the unit goes into pause mode (the play/
pause LED will blink). Move the SEARCH JOG WHEEL (14) or use

DIRECT ACCESS (6) buttons to memorize the spot at which you want
play to start, the CUE POINT, by selecting the proper track, minute,
second and frame. Push the CUE (12) button to set the cue. You can
do this in any mode, including PLAY MODE, so that you may cue a
track while playing a track. Press the CUE (12) button again to return
to the memorized cue point.
2. To fine tune a cue point, pause play at the memorized cue point (the
cue LED will glow and the play/pause LED will blink), then use the

frame by frame (1/75th of a second) to where you want play to begin
(the cue LED will blink while you scan). Press the PLAY/PAUSE (13)

AND/OR
TROUBLE SHOOTING
• If the disk will not play, check to see if the disc was loaded correctly
(label side up). Also check the disc for excessive dirt, scratches, etc.
• If the disc turns but there is no sound, check the cable connections. If
they are okay, check your amplifier or receiver.
• If the CD skips, check the CD for dirt or scratches. Do not assume
that the CD player is defective. Many CDs are recorded out of spec
and will skip on most or all CD players. Before sending the unit in for
repair, try playing a CD that you are sure plays properly.
