Understanding Radio Reception
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.

Downloaded from www.Manualslib.com manuals search engine 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 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.
2.
3.
4.
5.
Turn the ignition to RUN or ACC.
Turn the radio on.
Insert the scrubbing action cleaning cassette.
Within five seconds, press and hold the
REV and
FWD buttons at the same time for five seconds.
The tape symbol on the display will flash for two
seconds, showing that the cut tape detection feature
is no longer active.
Eject the cleaning cassette after the manufacturer’s
recommended cleaning time.

Downloaded from www.Manualslib.com manuals search engine If your vehicle is equipped with the AM-FM Stereo with
Cassette Tape Player and Automatic
Tone Control:
1. Turn the ignition to RUN or ACC.
2. Turn the radio off.
3. Press and hold the TAPE AUX button for five
seconds. The tape symbol
on the display will flash
for two seconds.
4. Insert the scrubbing action cleaning cassette while
the tape symbol is flashing.
5. 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 EJECT for
five seconds to reset the
CLN 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.

Downloaded from www.Manualslib.com manuals search engine Power Antenna Mast Care
Your power antenna will look its best and work
well if it’s cleaned from time to time. To clean the
antenna mast:
1.
2.
3.
4.
5.
6.
Turn on the ignition and radio to raise the antenna.
Dampen a clean cloth with mineral spirits or
equivalent solvent.
Wipe the cloth over the mast sections, removing
any dirt.
Wipe dry with a clean cloth.
Make the antenna go up and down by turning the
radio or ignition off and
on.
Repeat if necessary.
I NOTICE:
I Don’t lubricate the power antenna. Lubrication
could damage it.
NOTICE:
Before entering an automatic car wash, turn off
your radio to make the power antenna
go down.
This will prevent the mast from possibly getting
damaged.
If the antenna does not go down when
you turn the radio off, it may be damaged or
need to be cleaned. In either case, lower the
antenna by hand by carefully pressing the
antenna down.
If the mast portion of your antenna is damaged, you can
easily replace it. See your dealer for a replacement kit
and follow the instructions in the kit.
