AM
The range for most AM stations is greater than for
FM, especially at night. The longer range, however, can
cause stations to interfere with each other. AM can pick
up noise from things like storms and power lines. Try
reducing the treble to reduce this noise if you ever get it.
FM Stereo
FM stereo will give you the best sound, but FM signals
will reach only about 10 to 40 miles (16 to 65 km). Tall
buildings or hills can interfere with FM signals, causing
the sound to come and go.

3-38 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 CLN or 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 dealership
(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 cut 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.
If your vehicle is equipped with the AM
-FM Stereo with
Cassette Tape Player:
1. Turn the ignition to ON or ACC.
1. Turn the radio off.
2. Press and hold the TAPE button for five
seconds. CAS will flash on the display will flash
for five seconds.
3. Insert the scrubbing action cleaning cassette.
4. Eject the cleaning cassette after the manufacturer's
recommended cleaning time.

If your vehicle is equipped with the AM-FM Stereo with
Cassette Tape Player with Radio Data System and
Automatic Tone Control or the AM
-FM Stereo with
Cassette Tape and Compact Disc Player with Radio Data
System and Automatic Tone Control:

Turn the ignition to ON or ACC.

Turn the radio off.

Press and hold the TAPE AUX or TAPE CD button
for five seconds. READY will appear on the display
for five seconds.

Insert the scrubbing action cleaning cassette.

Eject the cleaning cassette after the manufacturer's
recommended cleaning time.
When the cleaning cassette has been ejected, the cut tape
detection feature is active again.
You may also choose a non
-scrubbing action, wet-type
cleaner which uses a cassette with a fabric belt to clean
the tape head. 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.After you clean the player, press and hold the eject or
EJT button for five seconds to reset the CLN or CLEAN
indicator. The radio will display
--- to show the
indicator was reset.
Cassettes are subject to wear and the sound quality may
degrade over time. Always make sure the cassette tape is in
good condition before you have your tape player serviced.
Care of Your Compact Discs
Handle discs carefully. Store them in their original cases
or other protective cases and away from direct sunlight
and dust. If the surface of a disc is soiled, dampen a
clean, soft cloth in a mild, neutral detergent solution and
clean it, wiping from the center to the edge.
Be sure never to touch the signal surface when handling
discs. Pick up discs by grasping the outer edges or the
edge of the hole and the outer edge.
Care of Your Compact Disc Player
The use of CD lens cleaner discs is not advised, due to
the risk of contaminating the lens of the CD optics with
lubricants internal to the CD mechanism.
