How vehicle audio works
AM and FM radio signals are broad-
cast from transmitter towers located
around your city. They are intercept-
ed by the radio antenna on your vehi-
cle. 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 possible quality
reproduction. However, in some
cases the signal coming to your vehi-
cle 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 sta-
tions or the presence of buildings,
bridges or other large obstructions in
the area.
AM broadcasts can be received at
greater distances than FM broad-
casts. This is because AM radio
waves are transmitted at low fre-
quencies. These long, low frequency
radio waves can follow the curvature
of the earth rather than travelling
straight out into the atmosphere. In
addition, they curve around obstruc-
tions so that they can provide better
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 equipment. In such a case,
use the cellular phone at a place as
far as possible from the audio equip-
ment.
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 permis-
sion. 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 analogue disc onto CDs.
• To prevent the disc surface from
getting 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 insert-
ed into the CD player (Do not insert
more than one CD at a time).
• Keep CDs in their cases after use
to protect them from scratches or
dirt.
CAUTION
When using a communication
system such as 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 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.
