Care of Your Cassette Tape Player
A tape player that is not cleaned regularly can cause
reduced sound quality, ruined cassettes or a damaged
mechanism. Cassette tapes should be stored in their
cases away from contaminants, direct sunlight and
extreme heat. If they aren’t, they may not operate
properly or may cause failure of the tape player.
Your tape player should be cleaned regularly after
every 50 hours of use. Your radio may display CLEAN
to indicate that you have used your tape player for
50 hours without resetting the tape clean timer. If this
message appears on the display, your cassette tape
player needs to be cleaned. It will still play tapes, but
you should clean it as soon as possible to prevent
damage to your tapes and player. If you notice a
reduction in sound quality, try a known good cassette to
see if it is the tape or the tape player at fault. If this other
cassette has no improvement in sound quality, clean the
tape player.
The recommended cleaning method for your cassette
tape player is the use of a scrubbing action,
non
- abrasive cleaning cassette with pads which scrub
the tape head as the hubs of the cleaner cassette turn.
The recommended cleaning cassette is available through
your dealer (GM Part No. 12344789).
When using a scrubbing action, non - abrasive cleaning
cassette, it is normal for the cassette to eject because
your unit is equipped with a broken tape detection
feature and a cleaning cassette may appear as a broken
tape. To prevent the cleaning cassette from being
ejected, use the following steps.
1. Turn the ignition to RUN or ACCESSORY.
2. Turn the radio off.
3. Press and hold the TAPE CD button for five seconds.
READY will appear on the display and a cassette
icon will flash for five seconds.
4. Insert the scrubbing action cleaning cassette.
5. Eject the cleaning cassette after the manufacturer’s
recommended cleaning time.
