FM broadcasts are transmitted at high fre- quencies and do not bend to follow the earth'ssurface. Because of this, FM broadcasts gen-erally begin to fade at short distances from thestation. Also, FM signals are easily affected bybuildings, mountains, or other obstructions.These can result in certain listening conditionswhich might lead you to believe a problemexists with your radio. The following conditionsare normal and do not indicate radio trouble:
Buildings
Obstructed area Iron bridges
Unobstructed area
FM radio station
SSAR012A
Mountains
Ionosphere
SSAR011A
AM reception
AM broadcasts can be received at greater distances than FM broadcasts. This is becauseAM radio waves are transmitted at low frequen-cies. These long, low frequency radio wavescan follow the curvature of the earth rather thantravelling straight out into the atmosphere. Inaddition, they curve around obstructions sothat they can provide better signal coverage.

AM and FM radio signals are broadcast from transmitter towers located around your city.They are intercepted by the radio antenna onyour car. This signal is then received by theradio and sent to 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 may not be strong and clear. This canbe due to factors such as the distance from theradio station, closeness of other strong radiostations or the presence of buildings, bridgesand other large obstructions in the area.

1- 64 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 suchas a cellular phone or a radio 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 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 be- ing received from several directions cancause distortion or fluttering. This can becaused by a direct and a reflected signalfrom the same station, or by signals fromtwo stations with close frequencies. If thisoccurs, select another station until the con-dition 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,we suggest that you select another strongerstation.
o Flutter/Static - Weak FM signals or large obstructions between the transmitter andyour radio can disturb the signal causingstatic or fluttering noises to occur. Reducingthe treble level may lessen this effect untilthe disturbance clears.
