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 by buildings, mountains, or other obstruc- tions. These can result in certain listen-ing conditions which might lead you to believe a problem exists with your ra- dio. The following conditions are normaland do not indicate radio trouble:
AM broadcasts can be received atgreater distances than FM broadcasts. This is because AM radio waves are transmitted at low frequencies. Theselong, low frequency radio waves can follow the curvature of the earth rather than travelling straight out into theatmosphere. In addition, they curve around obstructions so that they can provide better signal coverage.
B750A02A-AAT STEREO SOUND SYSTEM How Car Audio Works
AM and FM radio signals are broad- cast from transmitter towers located around your city. They are intercepted by the radio antenna on your car. Thissignal is then received by the radio and sent to your car speakers. When a strong radio signal has reachedyour vehicle, the precise engineering of your audio system ensures the best possible quality reproduction. Howev-er, in some cases the signal coming to your vehicle may not be strong and clear. This can be due to factors suchas the distance from the radio station, closeness 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 maybegin to play. This is because your radio is designed to lock onto the clearest 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 or fluttering. This can be caused by adirect and reflected signal from the same station, or by signals from two stations with close frequencies. Ifthis occurs, select another station until the condition has passed.
o Fading - As your car moves away
from the radio station, the signal will weaken and sound will begin tofade. When this occurs, we suggest that you select another stronger sta- tion.
o Flutter/Static - Weak FM signals or large obstructions between thetransmitter and your radio can dis-turb the signal causing static or flut- tering noises to occur. Reducing the treble 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 produced from the audio equipment. This doesnot mean that something is wrong with the audio equipment. In such a case, use the cellular phone at a place as faras possible from the audio equipment.

CAUTION:
When using a communication sys- tem such a cellular phone or a radio set inside the vehicle, a separateexternal antenna must be fitted. When a cellular phone or a radio set is used with an internal antennaalone, it may interfere with the vehicle's electrical system and ad- versely affect safe operation of thevehicle.
WARNING:
Don't use a cellular phone whenyou are driving. Stop at a safe 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 a wavering sound. They should be cleaned monthly using a commer-cially available head cleaning tape or special solution available from audio specialty shops. Follow the supplier'sdirections carefully and never oil any part 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 the drive 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 pencil or your finger. If the label is peeling off, do not putit in the drive mechanism. Do not leave tapes sitting where they are exposed to hot, warm, orhigh humidity, such as on top of the dashboard or in the player. If a tape is exposed to excessivelyhot or cold, let it reach a moderate temperature before putting it in the player.B870B01Y-AAT ANTENNA Power Antenna (If installed) The antenna will automatically be ex- tended when the radio power switch isturned on while the ignition key is in either the "ON" or "ACC" position. The antenna will automatically be retractedand stored when either the radio power switch is turned off or the ignition key is set to the "LOCK" position. B870B03L

B870D01L-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 will receive both AM and FM broadcastsignals 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 use a scraper to remove the foreigndeposits from the inner surface of the glass as this may cause damage to the antenna elements.
o Avoid adding metalic coating (Some aftermarket window tintinghas a metallic contents). Thesecan disturb receiving AM and FM broadcast signals.
