FM reception

AM and FM radio signals are broadcast from transmitter towers located around your city. They are intercepted by the radio antenna on your car. This signal isthen 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 some casesthe signal coming to your vehicle is not strong and clear. This can be due to factors such as the distance from theradio station, closeness of other strong radio stations or the presence of build- ings, bridges or other large obstructionsin the area. 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 the iono-sphere. In addition, they curve around obstructions so that they can provide better signal coverage.

FM broadcasts are transmitted at high frequency and do not bend to follow the 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 build- ings, mountains, or other obstructions. These can result in certain listeningconditions which might lead you to believe a problem exists with your ra- dio. The following conditions are normaland do not indicate radio trouble:

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 radio set inside the vehicle, a separate external antenna must be fitted.When a cellular phone or a radio set is used with an internal antenna alone, it may interfere with thevehicle's electrical system and ad- versely affect safe operation of the vehicle.
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 station.
o Flutter/Static - Weak FM signals or large obstructions between the trans-mitter and your radio can disturb thesignal causing static or fluttering noises to occur. Reducing the treble level may lessen this effect until thedisturbance clears. o Station Swapping - As a FM signal
weakens, another more powerfulsignal 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 a reflected signal from the same station, or by signals fromtwo stations with close frequencies. If this occurs, select another station until the condition has passed.

B880C02B-EAT Glass Antenna (Not all models) When the radio power switch is turned on whilst the ignition key is in either the "ON" or "ACC" position, your car will receive both AM and FM broadcastsignals through the antenna in the rear quarter glass. CAUTION:
o Do not clean the inner side of the rear quarter glass with an abra- sive type of glass cleaner or usea scraper to remove foreign de- posits from the inner surface of the glass as this may cause dam-age to the antenna elements.
o Avoid adding metallic coating
such as Ni, Cd, and so on. Thesecan disturb receiving AM and FM broadcast signals.
