3-27 Radio Personalization with Home and Away
Feature (If Equipped)
If your vehicle is equipped with the AM-FM Stereo with
Cassette Tape Player and 1 (H or A) or 2 (H or A)
appears in the display when the radio is first turned on,
your vehicle is equipped with this feature. If your
vehicle is equipped with any other audio system and
DRIVER 1 (HOME or AWAY) PRESETS or DRIVER 2
(HOME or AWAY) PRESETS appears in the display
when the radio is first turned on, your vehicle is
equipped with this feature.
With this feature, your vehicle will recall the latest radio
settings as adjusted the last time your vehicle was
operated. This feature allows two different drivers to
store and recall their own radio settings. The settings
recalled by the radio are determined by which Remote
Keyless Entry (RKE) transmitter (ª1º or ª2º) was used
to enter the vehicle. The number on the back of the RKE
transmitter corresponds to driver 1 or to driver 2. The
radio settings will automatically adjust to where they
were last set by the identified driver. The settings can
also be recalled by briefly pressing the MEMORY seat
buttons 1 or 2 located on the driver's door.Your radio can store home and away presets. Home and
away presets allow you to use one set of preset radio
settings in the area where you live, and another set when
you go out of town. That way, you will not need to
reprogram your presets every time you travel. With the
radio off and the clock displayed, use FF and RW to
select home or away presets. To select the away presets,
press and hold FF for five counts until you hear a beep.
The next time the radio comes on, the away presets will
be active. To select the home presets, press and hold RW
for five counts until you hear a beep. The next time the
radio comes on, the home presets will be active.
When battery power is removed and later applied, you
will not have to reset your home radio presets because
the radio remembers them. However, you will have to
reset your away radio presets.

SELECT: When listening to the radio, press the up or
down arrow lever to tune to the next or previous preset
radio station. (If your vehicle is equipped with the
AM
-FM Stereo with Cassette Tape Player, factory
presets which have not been reprogrammed with your
stations will be ignored). When listening to a cassette
tape, the up or down arrow lever can be used to SEEK
forward and rearward through the tape. Pressing the up
or down arrow lever when listening to a CD will cause
the player to go to the next or previous selection. When
in Radio Data Systems (RDS) Program Type (PTY)
mode, the up or down arrow lever can be used to
perform a PTY preset seek. PSEEK will appear on the
display while the PTY preset seek is performed. The
radio will seek all of the PTYs stored in presets, except
for the PTY Any.
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). Tall
buildings or hills can interfere with FM signals, causing
the sound to come and go.
Weather Band (If Equipped)
Weather band is restricted to speech and the audio
quality is not as good as with the AM or FM bands.
Depending on location, the radio should receive one or
two channels.
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, radio or other systems, and
even damage them. Your vehicle's systems may
also 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 or
CLEAN TAPE 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 because
your unit is equipped with a cut tape detection feature
and a cleaning cassette may appear as a broken tape. To
prevent the cleaning cassette from being ejected, use the
following steps.
1. Turn the ignition to RUN or ACCESSORY.
2. Turn the radio off.

yellowblue
3-31
3. Press and hold the SOURCE button for two
seconds. The tape symbol on the display will flash
three times.
4. Turn the radio on and 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.
If your vehicle is equipped with the AM
-FM Stereo with
Cassette Tape Player, press and hold the eject button for
five seconds to reset the CLN indicator after you clean
the player. The radio will display
--- to show the
indicator was reset.If your vehicle is equipped with any other radio, press
and hold the eject button for three seconds to reset the
CLEAN TAPE indicator after you clean the player. The
radio will display CLEAN TAPE MSG CLEARED 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.
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.
