Downloaded from www.Manualslib.com manuals search engine Delco LOC /I Theft Deterent Feature
Delco LOC II@ is an anti-theft feature for the compact disc player. It can be
used or ignored. If ignored, the system plays normally. If it is used, your
player won’t be usable
if it is ever stolen, because it will go to LOC mode
any time the battery power is removed. After a
loss of battery power, the
player cannot be turned on unless an unlock code is entered.
The instructions below tell you how to enter
a secret code into the system. If
your vehicle loses battery power for any reason, you must unlock the system
with the secret code before the radio will turn on.
To Lock The System:
1. Write down any 6 digit number and keep it in a safe place.
2. Turn the ignition to the ACC (Accessory) or RUN position.
3. Press the PWR knob to turn the radio off.
4. Press the 1 and 4 buttons together. Hold them down until “- - -” shows
on the display.
You are now ready to enter your secret code. Don’t wait more than 15
seconds between steps.
5. Press SET and “000” will appear on the display.
6. Press the SEEK or 4 button to make the first number appear.
7. Press SCAN to make the next two numbers agree with your code.

6. Press the BAND knob. If the display shows “- - - ”, the disabling
sequence was successful. The numbers matched the user-selected code
or the factory back-up code, and the
unit is in the UNSECURED
mode. If
the display shows “SEC”, the disabling sequence was
unsuccessful and
the numbers did not match either of the codes and the
unit will remain
in the SECURED mode.
Understanding Radio Reception
FM stereo will give you the best sound. But FM signals will reach only
about 10 to 40 miles (16 to 65 km). And, tall buildings or hills can interfere
with FM signals, causing the sound to come and
go.
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.
AM Stereo means the DelcoB system can receive C-QUAM@stereo
broadcasts. Many AM stations around
the countr use C-QUAM@ to
produce stereo, though some do not. (C-QUAM
4 is a registered trademark
of Motorola, Inc.) If your Delco@ system can get C-QUAM@, your
“STEREO” light
will come on when you’re receiving it.
Be aware that 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.
3-18

Downloaded from www.Manualslib.com manuals search engine To help avoid hearing loss or damage:
1. Adjust the volume control to the lowest setting.
2. 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. And, 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 Player and Tape
A tape player that is not cleaned regularly is subject to reduced sound
quality, ruining
the cassette, or damaging the mechanism. Tape cassettes that
are not properly stored
in their plastic cases away from contaminants, direct
sunlight, and extreme heat, may not operate properly and could cause
premature failure
of the tape player.
Your tape player should be cleaned with every
50 hours of use to provide
optimum performance. Your radio may display “Cln” (Clean)
to indicate
that you have used your tape player for
50 hours without re-setting the tape
clean timer. If you notice a reduction
in sound quality, regardless of when
the tape player was last cleaned, try playing
a different cassette to see if the
tape or tape player is at fault. If
the second cassette results in no
improvement
in sound quality, try cleaning the tape player.
Proper tape player cleaning should be done with a scrubbing action,
non-abrasive cleaning cassette. This is a wet-type cleaning system that uses
a cleaning cassette with pads which scrub the tape head as the hubs of the
cleaner cassette turn. To properly clean your tape player, follow instructions
with the cleaning cassette. If
you use this type of cleaner, the radio may
display an error and eject the cartridge. This is normal and is the result of an
added feature
in the tape player that detects broken tapes. If an error occurs,
you will need to insert the cleaning cassette at least
3 times to thoroughly
clean the tape player.
3-19

Downloaded from www.Manualslib.com manuals search engine You may prefer to use a non-scrubbing action, wet-type cleaner. This type
of cleaner uses a fabric belt to clean the tape head. This type of cleaner
cassette will not
cause an error, but it may not clean the tape player as
thoroughly
as the scrubbing type cleaner.
A scrubbing action cleaner cassette is available through your retailer (SPO
12344600).
Cassettes are subject to wear and the sound quality may degrade over time.
Always verify that the cassette tape
is in good condition and the tape player
is clean before obtaining service on your tape player.
NOTICE:
Cassette tape adapter kits for portable CD players will not work
in your cassette player. These adapters will cause the radio t\
o
display an error and the adapter cassette
will be ejected.
Care of 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.
Antenna Care
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
fender.

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.
You could be injured if the vehicles roll. Set the parking brake firmly
on each vehicle. Put an automatic transmission in PARK
(P) or a
manual transmission in NEUTRAL (N).
If you have a
four-wheel-drive vehicle with
a manual transfer case shift lever, be
sure the transfer case is
not in NEUTRAL (N).
3. Turn off the ignition on both vehicles. Turn off all lights that aren’t
needed, and radios. This will avoid sparks and help save both batteries.
And it could save your radio!

NOTICE:
If you leave your radio on, it could be badly damaged. The
repairs wouldn’t be covered by your warranty.
4. Open the hoods and locate the batteries. Find the positive (+) and
negative
(-) terminals on each battery.
5. Check that the jumper cables don’t have loose or missing insulation. If
they do, you could get a shock. The vehicles could be damaged too.
Before
you connect the cables, here are some basic things you should
know. Positive
(+> will go to positive (+) and negative (-) will go to
negative
(-1 or a metal engine part. Don’t connect (+) to (-) or you’ll
get a short that would damage the battery and maybe other parts too.
