Care Of The Cassette Tape Player; Fixed Mast Antenna - GMC T-Series 2007 Owner's Manual

Care of the 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 are not,
they may not operate properly or may cause failure
of the tape player.
The tape player should be cleaned regularly after
every 50 hours of use. If there is a reduction in
sound quality, try a known good cassette to see
if the tape or the tape player is at fault. If this other
cassette has no improvement in sound quality,
clean the tape player.
For best results, use 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.

A non-scrubbing action, wet-type cleaner which
uses a cassette with a fabric belt to clean the tape
head can be used. This type of cleaning cassette
will not eject on its own. A non-scrubbing action
cleaner may not clean as thoroughly as the
scrubbing type cleaner. The use of a non-scrubbing
action, dry-type cleaning cassette is not
recommended.
Cassettes are subject to wear and the sound
quality may degrade over time. Always make
sure the cassette tape is in good condition before
the tape player is serviced.

Fixed Mast Antenna

The antenna is located in front of the driver's
