Theft-Deterrent Feature
THEFTLOCK" is designed to discourage theft of your
radio.
It works by using a secret code to disable all radio
functions whenever battery power is removed.
The THEFTLOCK feature for the radio may be used or
ignored. If ignored, the system plays normally and the
radio is not protected by the feature. If THEFTLOCK
is
activated, your radio will not operate if stolen.
When THEFTLOCK is activated, the radio will display
LOC to indicate
a locked condition anytime battery
power is removed. If your battery loses power for any
reason, you must unlock the radio with the secret code
before it will operate.

Understanding Radio Reception
FM Stereo
FM stereo will give you the best sound. But FM signals
will reach only about
10 to 40 miles (1 6 to 65 km). Tall
buildings
or hills can interfere with FM signals, causing
the sound to come and go.
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.

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.
Increase volume slowly until you hear comfortably
and clearly.
NOTICE:
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 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. Cleaning
may be done with a scrubbing action,
non-abrasive cleaning cassette with pads which scrub
the tape head as the hubs
of the cleaner cassette turn. It
is normal for the cassette to eject while cleaning because
your unit is equipped with a cut tape feature. To
temporarily override this feature for vehicles with
Automatic Tone Control (for one insertion), turn on the
ignition then turn the radio off and press and hold TAPE
AUX until the tape symbol flashes on the display, then
insert the cassette again. For vehicles without Automatic
Tone Control, press both
SEEK arrows within five
seconds of inserting the cassette with the ignition and
radio
off. Insert the cassette at least three times to ensure
thorough cleaning.
A scrubbing action cleaning cassette
is available through your
GM dealership.
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.
It may not clean as thoroughly as the scrubbing
type cleaner.

The cassette tape player is able to detect a broken tape.
Some cleaning cassettes may appear as
a broken tape. If
the cleaning cassette is ejected immediately from the
tape player, follow these steps:
1. Turn the radio off.
2. Turn the ignition on.
3. Press and hold the TAPE-AUX button until the tape

in cassette mode.
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.
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.
