FM broadcasts are transmitted at high fre- quency 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:

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 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 and otherlarge obstructions in the area.

AM reception
AM broadcasts can be received at greater distances than FM broadcasts. This is becauseAM radio waves are transmitted at low fre-quency. 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.

CONTROLS AND EQUIPMENTB750B02Y-AAT Using a cellular phone or a two-way radio When a cellular phone is used inside the vehicle, noise may be produced from theaudio equipment. This does not mean thatsomething is wrong with the audio equipment.In such a case, use the cellular phone at aplace as far as possible from the audio equip-ment. CAUTION: When using a communication system such as a mobile phone or a radio inside thevehicle, a separate external antenna mustbe fitted.When a mobile phone or a radio set isused with an internal antenna alone, it mayinterfere with the vehicle's electrical sys-tem and adversely affect safe operation ofthe vehicle. WARNING: Don't use a mobile phone when you are driving, you must stop at a safe place touse a mobile 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 be- ing 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 an-other 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,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.

This can be caused by adirect and a 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.
