FM broadcasts are transmitted at high frequency and do not bend to followthe earth's surface. Because of this, FM broadcasts generally begin to fade at short distances from the station.Also, FM signals are easily affected by buildings, mountains, or other obstruc- tions. These can result in certain lis-tening conditions which might lead you to believe a problem exists with your radio. The following conditions arenormal and do not indicate radio trouble:
AM broadcasts can be received atgreater distances than FM broadcasts. This is because AM radio waves are transmitted at low frequency. Theselong, low frequency radio waves can follow the curvature of the earth rather than travelling straight out into theatmosphere. In addition, they curve around obstructions so that they can provide better signal coverage.
B750A02A-AAT STEREO SOUND SYSTEM How Car Audio Works
AM and FM radio signals are broad- cast from transmitter towers located around your city. They are intercepted by the radio antenna on your car. Thissignal is then received by the radio and sent to your car speakers. When a strong radio signal has reachedyour vehicle, the precise engineering of your audio system ensures high quality reproduction. However, in somecases the signal coming to your ve- hicle is not strong and clear. This can be due to factors such as the distancefrom the radio station, closeness of other strong radio stations or the pres- ence of buildings, bridges or otherlarge obstructions in the area.

o Station Swapping - As a FM signal weakens, another more powerful signal near the same frequency may begin to play. This is because your radio is designed to lock onto theclearest signal. If this occurs, select another station with a stronger sig- nal.
o Multi-Path Cancellation - Radio sig- nals being received from severaldirections can cause distortion orfluttering. This can be caused by a direct and reflected signal from the same station, or by signals from twostations with close frequencies. If this occurs, select another station until the condition has passed.
o Fading - As your car moves away
from the radio station, the signal willweaken and sound will begin to fade. When this occurs, we suggest that you select another stronger sta-tion.
o Flutter/Static - Weak FM signals or
large obstructions between thetransmitter and your radio can dis- turb the signal causing static or flut- tering noises to occur. Reducing thetreble level may lessen this effect until the disturbance clears. B750B02Y-DAT Using a mobile phone or a two- way radio When a mobile phone is used inside the vehicle, noise may be produced from the audio equipment. This does notmean that something is wrong with the audio equipment. In such a case, use the mobile phone at a place as far aspossible from the audio equipment.
!
CAUTION:
When using a communication sys- tem such a mobile phone or a radio set inside the vehicle, a separateexternal antenna must be fitted. When a mobile phone or a radio set is used with an internal antennaalone, it may interfere with the vehicle's electrical system and ad- versely affect safe operation of thevehicle.
WARNING:
Don't use a mobile phone when youare driving, you must stop at a safe place to use a mobile phone.
