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 the best possible quality repro-duction. However, in some cases the signalcoming to your vehicle may not be strong andclear. This can be due to factors such as thedistance from the radio station, closeness ofother strong radio stations or the presence ofbuildings, bridges or other large obstructions inthe area. AM broadcasts can be received at greater dis-tances than FM broadcasts. This is because AMradio waves are transmitted at low frequencies.These long, low frequency radio waves canfollow the curvature of the earth rather thantravelling straight out into the atmosphere. Inaddition, they curve around obstructions so thatthey can provide better signal coverage.
FM broadcasts are transmitted at high frequen-cies 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:

SSAR014A 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 equip-ment. This does not mean that something iswrong with the audio equipment. In such a case,use the cellular phone at a place as far aspossible from the audio equipment. CAUTION: When using a communication system such acellular phone or a radio set inside the vehi-cle, a separate external antenna must befitted. When a cellular phone or a radio set isused with an internal antenna alone, it mayinterfere with the vehicle's electrical systemand adversely affect safe operation of thevehicle. WARNING: Don't use a cellular phone when you aredriving. Stop at a safe place to use a cellularphone.SSAR013A
o Station Swapping - As an FM signal weak-ens, another more powerful signal near the same frequency may begin to play. This isbecause your radio is designed to lock ontothe clearest signal. If this occurs, selectanother station with 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 reflected signal from the samestation, or by signals from two stations withclose frequencies. If this occurs, select an-other station until the condition has passed.
o Fading - As your car moves away from the
radio station, the signal will weaken and soundwill 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.
