How vehicle audio works
AM and FM radio signals are broadcast
from transmitter towers located around
your city. They are intercepted by the
radio antenna on your vehicle. This signal
is then received by the radio and sent to
your vehicle speakers.
When a strong radio signal has reached
your vehicle, the precise engineering of
your audio system ensures the best pos-
sible quality reproduction. However, in
some cases the signal coming to your
vehicle may not be strong and clear.This can be due to factors, such as the
distance from the radio station, close-
ness of other strong radio stations or the
presence of buildings, bridges or other
large obstructions in the area.
AM broadcasts can be received at
greater distances than FM broadcasts.
This is because AM radio waves are
transmitted at low frequencies. These
long, low frequency radio waves can fol-
low the curvature of the earth rather than
travelling straight out into the atmos-
phere. In addition, they curve around
obstructions so that they can provide bet-
ter signal coverage.

Using a cellular phone or a two-way
radio
When a cellular phone is used inside the
vehicle, noise may be produced from the
audio system. This does not mean that
something is wrong with the audio equip-
ment. In such a case, use the cellular
phone at a place as far as possible from
the audio equipment.
Caring for disc
• If the temperature inside the car is too
high, open the car windows to ventilate
before using the system.
• It is illegal to copy and use MP3/WMA
files without permission. Use CDs that
are created only by lawful means.
• Do not apply volatile agents, such as
benzene and thinner, normal cleaners
and magnetic sprays made for ana-
logue disc onto CDs.
• To prevent the disc surface from get-
ting damaged, hold CDs by the edges
or the center hole only.
• Clean the disc surface with a piece of
soft cloth before playback (wipe it from
the center to the outside edge).
• Do not damage the disc surface or
attach pieces of sticky tape or paper.
• Make certain only CDs are inserted
into the CD player (Do not insert more
than one CD at a time).
• Keep CDs in their cases after use to pro-
tect them from scratches or dirt.
• Depending on the type of CD-R/CD-
RW CDs, certain CDs may not operate
normally according to manufacturing
companies or making and recording
methods. In such circumstances, con-
tinued use may cause malfunctions to
your audio system.
CAUTION
When using a communication sys-
tem such as a cellular phone or a
radio set inside the vehicle, a sepa-
rate external antenna must be fitted.
When a cellular phone or a radio set
is used with an internal antenna
alone, it may interfere with the vehi-
cle's electrical system and adversely
affect safe operation of the vehicle.
WARNING
Do not use a cellular phone while
driving. Stop at a safe location to
use a cellular phone.
