Tips About Your Audio System
Hearing damage from loud noise is almost undetectable
until
it is too late. Your hearing can adapt to higher
volumes of sound. Sound that seems normal can be loud
and harmful
to your hearing. Take precautions by
adjusting the volume control on your radio to a safe
sound level before your hearing adapts to
it.
To help avoid hearing loss or damage:
Adjust the volume control to the lowest setting.
0 Increase volume slowly until you hear comfortably
and clearly.
NOTICE: F
Before you add any sound equipment to your
vehicle -- like a tape player, CB radio, mobile
telephone or two-way radio
-- be sure you can
add what you want.
If you can, it’s very
important to do it properly. Added sound equipment may interfere with the operation
of
your vehicle’s engine, Delco Electronics radio or
other systems, and even damage them. Your
vehicle’s systems may interfere with the
operation of sound equipment that has been
added improperly.
So, before adding sound equipment, check with
your dealer and be sure to check Federal rules
covering mobile radio and telephone units.

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 while
cleaning because your
unit is equipped with a cut tape
detection feature and some cleaning cassettes may
appear as
a broken tape. To prevent the cleaning cassette
from being e-jected, 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 ACCESSORY.
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 three seconds. The
tape symbol on the display will flash, showing that
the cut tape detections feature is no longer active.
Eject the cleaning cassette after the manufacturer's
recommended cleaning time.
3-25
ProCarManuals.com

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 ACCESSORY.
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.
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 Incake sure the cassette tape is in
good condition before you have yo~~r 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.
Fixed Mast Antenna
The fixed mast antenna can withstand most car washes
without being damaged.
If the mast should ever become
slightly bent, you can straighten
it out by hand. If the
mast is badly bent, as it might be by vandals, you should
replace it.
Check every once
in a while to be sure the mast is still
tightened
to the cowl.
