FM broadcasts are transmitted at high frequencies and do not bend to followthe earth's surface. Because of this,FM broadcasts generally begin to fade at short distances from the station. Also, FM signals are easily affected bybuildings, mountains, or other obstruc-tions. These can result in certain listen-ing conditions which might lead you tobelieve a problem exists with your ra- dio. The following conditions are normal and do not indicate radio trouble:
AM broadcasts can be received atgreater distances than FM broadcasts.This is because AM radio waves aretransmitted at low frequencies. Theselong, low frequency radio waves canfollow the curvature of the earth rather than travelling straight out into the atmosphere. In addition, they curvearound obstructions so that they canprovide better signal coverage.
B750A02A-AAT STEREO SOUND SYSTEM How Car Audio Works AM and FM radio signals are broad- cast from transmitter towers locatedaround your city. They are interceptedby the radio antenna on your car. Thissignal is then received by the radio andsent to your car speakers. When a strong radio signal has reached your vehicle, the precise engineeringof your audio system ensures highquality reproduction. However, in somecases the signal coming to your ve-hicle may not be strong and clear. This can be due to factors such as the distance from the radio station, close-ness of other strong radio stations or the presence of buildings, bridges orother large obstructions in the area.

o Station Swapping - As a FM signal weakens, another more powerful signal near the same frequency may begin to play. This is because yourradio is designed to lock onto theclearest signal. If this occurs, selectanother station with a stronger sig-nal.
o Multi-Path Cancellation - Radio sig-
nals being received from severaldirections can cause distortion orfluttering. This can be caused by adirect and reflected signal from thesame station, or by signals from two stations with close frequencies. If this occurs, select another stationuntil the condition has passed.
o Fading - As your car moves away
from the radio station, the signal will weaken and sound will begin to fade. When this occurs, we suggestthat you select another stronger sta-tion.
o Flutter/Static - Weak FM signals or large obstructions between the transmitter and your radio can dis- turb the signal causing static or flut-tering noises to occur. Reducing thetreble level may lessen this effectuntil the disturbance clears. B750B02Y-AAT Using a cellular phone or a two- way radio When a cellular phone is used inside the vehicle, noise may be producedfrom the audio equipment. This doesnot mean that something is wrong withthe audio equipment. In such a case, use the cellular phone at a place as far as possible from the audio equipment.

CAUTION:
When using a communication sys- tem such a cellular phone or a radioset inside the vehicle, a separateexternal antenna must be fitted.When a cellular phone or a radio set is used with an internal antenna alone, it may interfere with thevehicle's electrical system and ad-versely affect safe operation of thevehicle.
WARNING:
Don't use a cellular phone whenyou are driving, you must stop at asafe place to use a cellular phone.

o The playback head, capstan and
pinch rollers will develop a coating of tape residue that can result in dete-rioration of sound quality, such as awavering sound. They should be cleaned monthly using a commer- cially available head cleaning tape orspecial solution available from audiospecialty shops. Follow the supplier'sdirections carefully and never oil anypart of the tape player unit.
o Always be sure that the tape is tightly
wound on its reel before inserting inthe player. Rotate a pencil in thedrive sprockets to wind up any slack. B860A03L
NOTE: Look at a tape before you insert it. If the tape is loose, tighten it byturning one of the hubs with a pencilor your finger. If the label is peeling off, do not put it in the drive mechanism.Do not leave tapes sitting wherethey are exposed to hot, warm, orhigh humidity, such as on top ofthe dashboard or in the player. If a tape is exposed to excessively hot or cold, let it reach a moderatetemperature before putting it in theplayer.B870B01Y-AAT Power Antenna (If installed) The antenna will automatically be ex- tended when the radio power switch isturned on while the ignition key is ineither the "ON" or "ACC" position. The antenna will automatically be retracted and stored when either the radio powerswitch is turned off or the ignition keyis set to the "LOCK" position. B870B03L

B870D02Y-GAT Glass Antenna (If installed)
When the radio power switch is turned on while the ignition key is in either the"ON" or "ACC" position, your car willreceive both AM and FM broadcast signals through the antenna in the rear window glass. RADIO "ON"
CAUTION:
o Before turning on the radio, make sure that no one is near the an- tenna.
o Before entering an automatic car wash or a place with a low heightclearance, be sure that the an-tenna is retracted and stored.
o If the antenna is dirty, be sure to
clean it in order to avoid an op-eration malfunction. CAUTION:
o Do not clean the inner side of the rear window glass with an abra-sive type of glass cleaner or usea scraper to remove the foreigndeposits from the inner surfaceof the glass as this may cause damage to the antenna elements.
o Avoid adding metalic coating such as Ni, Cd, and so on. These can disturb receiving AM and FMbroadcast signals.
