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
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). Tcd1
buildings or hills can interfere with FM signals, causing
the sound to come and go.
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 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 retailer and be sure to check Federal rules
covering mobile radio amd 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 sh0~11d 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 fwlt.
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 retail facility
(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. If
the cleaning cassette ejects, insert the cassette at least
three times to ensure thorough cleaning.
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.

2. Get the vehicles close enough so the jumper cables
can reach, but be sure the vehicles aren’t touching
each other.
If they are, it could cause a ground
connection you don’t want. You wouldn’t be able to
start your vehicle, and the bad grounding could
damage the electrical systems.
To avoid the possibility of the vehicles rolling, set
the parking brake firmly
on both vehicles involved in
the procedure. Put an automatic transmission vehicle
in
PARK (P) and a manual transmission vehicle in
NEUTRAL (N).
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter, or accessory power outlets,
if you have this
option. Turn
off all lamps that aren’t needed as well
as radios. This will avoid sparks and help to save
both batteries. In addition,
it could save your radio!
NOTICE:
If you leave your radio on, it could be badly
damaged. The repair wouldn’t be covered by
your warranty.
An electric fan can start up even when the engine
is not running and can injure you. Keep hands,
clothing and tools away from any underhood
electric fan.

Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits
by a combination of fuses and circuit
breakers. This greatly reduces the chance of fires caused
by electrical problems.
Look at the silver-colored band inside the f~~se. If the
band is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one of the identical size
and rating.
If you ever have a problem on the road and don’t have a
spare fuse, you can borrow one that has the same
amperage. Just
pick some feature of your vehicle that
you can get along without
-- like the radio or cigarette
lighter
-- and use its fuse, if it is the correct amperage.
Replace
it as soon as you can.
