If you have an ETR@
AM-FM Stereo Audio
Compact Disc ATC
System that includes a
remote cassette player,
the cassette player is
located in the center
panel.
, of the instrument
Your tape player is built
to work best with tapes that are 30 to 45 minutes
long
on each side. Tapes longer than that are so thin they may not work well
in this player.
To load a cassette tape with the ignition off, first press EJECT. Then, insert
the cassette tape.
Once
the tape is playing, use the control knobs for volume, balance, fade,
treble and bass just as you do for the radio. A lighted tape symbol shows
when a cassette tape is in the player. A lighted arrow will also appear and
show
the direction of play when a tape is active.
The player automatically senses
if the cassette tape is metal or CRO2 and
adjusts for best playback sound. For metal tapes,
00 (Dolby@ Noise
Reduction) will appear in the display.
Any time a cassette tape is inserted, the top side is selected for play first.
PREV
(1) - Press PREV or 4 SEEK (in the opposite direction that the
lighted tape direction arrow points) to search for the previous selection.
A
minimum three-second blank gap is needed for the player to stop at the
beginning
of the selection. The tape direction arrow will blink during the
SEEK operation and
the audio is in the mute mode.
PROG
(on cassette player) - Press PROG to go from one side of the tape
to the other.
NEXT
(3) - Press NEXT or SEEK (in the direction that the lighted tape
direction arrow points) to search for the next selection. A minimum
three-second blank gap is needed for the player
to stop at the beginning of
the selection. NEXT will appear in the display and the audio is in the mute
mode.

press the AMEM button. To return to the tape player, press CD AUX. The
lighted arrow
will appear next to the tape symbol and show the direction of
play when a tape is active.

- To remove the tape press the EJECT button.
EJECT
can be used with either the ignition or radio off. Also, you must
press EJECT before loading
a cassette with the radio off to allow loading.

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
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.

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 Tapes
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.
3-27
ProCarManuals.com

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 to
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.
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
fender.

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!
I NOTICE:
If you leave your radio on, it could be badly damaged. The
repairs wouldn’t be covered by your warranty.
Open the hoods and locate the batteries. Find the positive (+) and
negative
(-) terminals on each battery.
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 (-) 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.

Fuse Block
The fuse block access
door is on the driver’s
side edge
of the
instrument panel. Pull
off the cover to access
the fuse block.
You can remove fuses
with a fuse extractor.
The
fuse extractor is
mounted to the fuse
block access door.
To remove fuses if you don’t have a fuse extractor, hold the end of the fuse
between your thumb and index finger and pull straight
out.
Be sure to use the correct fuse. If you ever have a problem on the road and
don’t
have a spare fuse, you can “borrow” one of the correct value. 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 of the value you need. Replace
it as soon as you can. See “Fuses and Circuit Breakers” in the Index for
more information.
