B750A02A-AAT How Car Audio Works
FM broadcasts are transmitted at high frequencies and do not bend to follow the earth's surface. Because of this, FM broadcasts generally begin to fadeat 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 yourradio. The following conditions are normal and do not indicate radio trouble:
AM broadcasts can be received at greater distances than FM broadcasts. This is because AM radio waves are transmitted at low frequencies. 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.
AM and FM radio signals are broadcastfrom transmitter towers located aroundyour city. They are intercepted by the radio antenna on your car. This signal is then received by the radio and sent toyour car speakers. When a strong radio signal has reached your vehicle, the precise engineering ofyour audio system ensures the best possible quality reproduction. Howev- er, in some cases the signal coming toyour vehicle may not be strong and clear. This can be due to factors such as the distance from the radio station,closeness of other strong radio stations or the presence of buildings, bridges or other large 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-AAT Using a cellular phone or a two- way radio When a cellular phone is used inside the vehicle, noise may be producedfrom the audio equipment. This does not mean that something is wrong with the audio equipment. In such a case,use the cellular phone at a place as far as possible from the audio equipment.!
CAUTION:
When using a communication sys- tem such a cellular phone or a radioset inside the vehicle, a separate external antenna must be fitted. When a cellular phone or a radio setis used with an internal antenna alone, it may interfere with the vehicle's electrical system and ad-versely affect safe operation of the vehicle.
WARNING:
Don't use a cellular phone whenyou are driving. Stop at a safe place to use a cellular phone.

HOW TO PRESET STATIONS Six AM and twelve FM stations may be programmed into the memory of theradio. Then, by simply pressing the band select button and/or one of the six station select buttons, you mayrecall any of these stations instantly. To program the stations, follow these steps:
o Press band selector to set the band for AM, FM1, or FM2.
o Select the desired station to be stored by seek or manual tuning.
o Determine the preset station select button you wish to use to access that station.
o Press the station select button for more than two seconds. A selectbutton indicator will show in the dis- play indicating which select buttonyou have depressed. The frequency display will flash after it has been stored into the memory with beepsound. You should then release the button, and proceed to program the next desired station. A total of 18stations can be programmed by se- lecting one AM and two FM stations per button. o When completed, any preset sta-
tion may be recalled by selectingAM, FM1 or FM2 band and the appropriate station button.
7. SCAN Button When the scan button is pressed, the frequency will be increased and the receivable stations will be tuned in oneafter another, receiving each station for 5 seconds. To stop scanning, press the scan button again.
