AUDIO SYSTEM CARE AND
CLEANING
Troubleshooting the CD
changer
The laser beam used in the
compact disc player is
harmful to the eyes. Do not
attempt to disassemble the case.
If sound skips:
²You may be traveling on a rough
road, playing badly scratched
discs or the disc may be dirty.
Skipping will not scratch the
discs or damage the player.
If changer does not work:
²A disc is already loaded where
you want to insert disc.
²The disc is inserted with the
label surface downward.
²The disc is dusty or defective.
²The player's internal
temperature is above 75ÉC
(167ÉF). Allow the player to
cool down before operating.
²A disc with format and
dimensions not within industry
standards is inserted.
Cleaning compact discs
Inspect all discs for contamination
before playing. If necessary, clean
discs only with an approved CD
cleaner and wipe the center out to
the edge. Do not use circular
motion.

CD and CD changer care
²Handle discs by their edges only.
Never touch the playing surface.
²Do not expose discs to direct
sunlight or heat sources for
extended periods of time.
²Do not insert more than one
disc into each slot of the CD
changer magazine.
Cleaning cassette player
Clean the tape player head with a
cassette cleaning cartridge after
ten to twelve hours of play to
maintain the best sound and
operation.
Cassette and cassette player
care
²Use only cassettes that are 90
minutes long or less.
²Do not expose tapes to direct
sunlight, high humidity, extreme
heat or extreme cold. Allow
tapes that may have been
exposed to extreme
temperatures to reach a
moderate temperature before
playing.
²Tighten very loose tapes by
inserting a finger or pencil into
the hole and turning the hub.
²Remove loose labels before
inserting tapes.
²Do not leave tapes in the
cassette player for a long time
when not being played.

Radio frequency information

RADIO FREQUENCY
INFORMATION
The Federal Communications
Commission (FCC) and the
Canadian Radio and
Telecommunications
Communications (CRTC) establish
the frequencies AM and FM
stations may use for their
broadcasts. Allowable frequencies
are:
AM 530, 540±1600, 1610 kHz steps
FM 87.9, 88.1±107.1, 107.9 Mhz
steps
Not all frequencies are used in a
given area.
RADIO RECEPTION FACTORS
Three factors can affect radio
reception:
²Distance/strength. The further
an FM station travels, the
weaker it is. The listenable
range of the average FM station
is approximately 40 km (24
miles). This range can be
affected by ªsignal modulation.º
Signal modulation is a process
radio stations use to increase
their strength/volume relative to
other stations.
²Terrain. Hills, mountains and tall
buildings between your vehicle's
antenna and the radio station
signal can cause FM reception
problems. Static can be caused
on AM stations by power lines,
electric fences, traffic lights,
driving under bridges and

thunderstorms. Moving away
from an interfering structure
(out of its ªshadowº) returns
your reception to normal.
²Station overload. Weak stations
are sometimes captured by
stronger stations when you pass
a broadcast tower. A stronger
station may temporarily
overtake a weaker station and
play while the weak station
frequency is displayed.
The audio system automatically
switches to single channel
reception if it will improve the
reception of a station normally
received in stereo.
