FM broadcasts are transmitted at high frequency and do not bend to follow the earth's surface.Because of this, FM broadcasts generally beginto fade at short distances from the station. Also,FM signals are easily affected by buildings, moun-tains, or other obstructions. These can result incertain listening conditions which might lead youto believe a problem exists with your radio. Thefollowing conditions are normal and do not indi-cate radio trouble:

AM reception
AM broadcasts can be received at greater dis- tances than FM broadcasts. This is because AMradio waves are transmitted at low frequency.These long, low frequency radio waves canfollow the curvature of the earth rather thantravelling straight out into the ionosphere. Inaddition, they curve around obstructions so thatthey can provide better signal coverage.

AM and FM radio signals are broadcast from transmitter towers located around your city. Theyare intercepted by the radio antenna on your car.This signal is then received by the radio and sentto your car speakers.When a strong radio signal has reached yourvehicle, the precise engineering of your audiosystem ensures high quality reproduction. How-ever, in some cases the signal coming to yourvehicle is not strong and clear. This can be dueto factors such as the distance from the radiostation, closeness of other strong radio stationsor the presence of buildings, bridges or otherlarge obstructions in the area.

CONTROLS AND EQUIPMENT
1- 82 B750B02Y-AAT Using a cellular phone or a two-way radio When a cellular phone is used inside the ve- hicle, noise may be produced from the audioequipment. This does not mean that somethingis wrong with the audio equipment. In such acase, use the cellular phone at a place as far aspossible from the audio equipment. CAUTION: When using a communication system sucha cellular phone or a radio set inside thevehicle, a separate external antenna mustbe fitted. When a cellular phone or a radioset is used with an internal antenna alone, itmay interfere with the vehicle's electricalsystem and adversely affect safe operationof the vehicle. WARNING: Don't use a cellular phone when you aredriving, you must stop at a safe place to usea cellular phone.

o Station Swapping - As a FM signal weakens, another more powerful signal near the same frequency may begin to play. This is becauseyour radio is designed to lock onto the clearestsignal. If this occurs, select another stationwith a stronger signal.
o Multi-Path Cancellation - Radio signals being received from several directions can causedistortion or fluttering. This can be caused bya direct and a reflected signal from the samestation, or by signals from two stations withclose frequencies. If this occurs, select anoth-er station until the condition has passed.SSAR013A
o Fading - As your car moves away from the radio station, the signal will weaken and sound will begin to fade. When this occurs, wesuggest that you select another stronger sta-tion.
o Flutter/Static - Weak FM signals or large obstructions between the transmitter and yourradio can disturb the signal causing static orfluttering noises to occur. Reducing the treblelevel may lessen this effect until the distur-bance clears.

B880C02B-EAT Glass Antenna (Not all models) When the radio power switch is turned on whilst the ignition key is in either the "ON" or "ACC"position, your car will receive both AM and FMbroadcast signals through the antenna in therear quarter glass. CAUTION:
o Do not clean the inner side of the rear quarter glass with an abrasive type of glass cleaner or use a scraper to removeforeign deposits from the inner surfaceof the glass as this may cause damage tothe antenna elements.
o Avoid adding metallic coating such as Ni, Cd, and so on. These can disturbreceiving AM and FM broadcast signals.

B870A01A-GAT ANTENNA Fixed Rod Antenna Your car uses a fixed rod antenna to receive
both AM and FM broadcast signals.
This antenna is a removable type. To remove
the antenna, turn the antenna counterclock- wise. To install the antenna, turn the antennaclockwise.
CAUTION: Be sure to remove the antenna before wash-
ing the car in an automatic car wash or the antenna may be damaged.
