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.

FM reception
SSAR010A
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. FM broadcasts are transmitted at high frequencyand 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:
Mountains
Buildings
Obstructed area Iron bridges
Unobstructed area

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 suchas a cellular phone or a radio inside thevehicle, 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, you must stop at a safe place to usea cellular phone.

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.SSAR014A
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.
