COMPACT DISCS
LOADING AND UNLOADING DISCS
8 cm disc Label surface
Disc tray
12 cm disc Label surface
Disc tray
If the disc tray is blocked while opening, the tray will stop and close
automatically after a few seconds.
3. When the disc tray has opened fully, remove a 12cm disc from its case
and place it carefully in the tray with the label side facing up, or remove
an 8 cm disc from its case and place it correctly in the inner groove of
the tray with the label side facing up.
NOTE:
Only load one disc at a time into the disc tray.
The side opposite the label is the signal side. Handle the disc carefully to
avoid leaving ngerprints on the disc surface.
4. To close the disc tray, press the OPEN/CLOSE button again. When the
tray with a correctly loaded disc is fully closed, the disc will start turning
automatically, and the total number of tracks will be read. The disc will
then stop and the TRACK display will change from "00" to indicate
the total number of tracks. The MUSIC CALENDAR will display the
total number of tracks (to a maximum of 16) and the TIME display will
show the total playing time of the disc in minutes and seconds. The CD
player will be set to the disc play standby mode.
5. The disc tray can be opened at any time by pressing the OPEN/
CLOSE button. Remove the disc only after the tray has fully opened.
CAUTION:
• Do not put anything except a compact disc into the tray. Foreign
objects can damage the mechanism.
• Do not force the tray by hand during the opening and closing
operations.
• To avoid dirt and dust entering the mechanism, keep the disc tray
closed when the CD player is not in use.
• Never load more than one disc into the disc tray.
This unit has been designed to play 8cm or 12cm compact discs bearing
the identication logo below. No other discs can be played.
• Always place the compact disc in the disc tray with the label facing
upward. Compact discs can be played on one side only.
• To remove a disc from its storage case, press down on the centre of
the case and lift the disc out, holding it carefully by the edges.
• Fingerprints and dust should be carefully wiped off the disc's signal
surface (glossy side) with a soft cloth. Unlike conventional records, the
compact disc has no grooves to collect dust and microscopic debris so
gently wiping with a soft cloth should remove most particles. Wipe with
a straight motion, from the inside to the outside of the disc. Small dust
particles and light stains will have absolutely no effect on reproduction
quality.
• Never use such chemicals as record cleaning sprays, antistatic sprays
or uids, benzene or thinners to clean compact discs. Such chemicals
would irreparably damage the disc's plastic surface.
• Discs should be returned to their cases after use to avoid serious
scratches that could cause the laser pickup to skip.
• Do not expose discs to direct sunlight, high humidity, or high
temperatures for extended periods. Long exposure to high
temperatures can warp a disc.
• Do not stick paper or write anything with a ball-point pen on the disc
surface.
HANDLING THE DISCS
1. Press the POWER switch.
(If the disc tray is already open, it will close automatically.)
2. Press the OPEN/CLOSE button. The disc tray will open.
