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 inthe 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.

Audio system
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 fade at short distances from
the station. Also, FM signals are eas-
ily affected by buildings, mountains,
or other obstructions. These can
result in certain listening conditions
which might lead you to believe a
problem exists with your radio. The
following conditions are normal and
do not indicate radio trouble: Fading - As your vehicle moves
away from the radio station, the
signal will weaken and sound will
begin to fade. When this occurs,
we suggest that you select anotherstronger station.
Flutter/Static - Weak FM signals or large obstructions between the
transmitter and your radio can dis-turb the signal causing static or
fluttering noises to occur. Reducing
the treble level may lessen this
effect until the disturbance clears. 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
the clearest signal. If this occurs,select another station with astronger signal.
Multi-Path Cancellation - Radio signals being received from sever-
al directions can cause distortion
or fluttering. This can be caused bya direct and reflected signal from
the same station, or by signals
from two stations with close fre-
quencies. If this occurs, selectanother station until the conditionhas passed.

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 system. This does notmean that something is wrong with
the audio equipment. In such a case,use the mobile 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 centre hole only.
Clean the disc surface with a piece of soft cloth before playback (wipeit from the centre to the outsideedge).
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 insertmore 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 mobile phoneor a radio set inside the vehicle, a separate external antennamust be fitted. When a mobilephone or a radio set is used with an internal antenna alone,it may interfere with the vehi-cle's electrical system andadversely affect safe operation of the vehicle.
WARNING
Do not use a mobile phone
whilst driving. Stop at a safe
location to use a mobile phone.

Audio system
Depending on the type of CD-R/CD-RW CDs, certain CDs may
not operate normally according to
manufacturing companies or mak-
ing and recording methods. In such
circumstances, continued use may
cause malfunctions to your audiosystem.
✽✽ NOTICE - Playing an
Incompatible Copy
Protected Audio CD
Some copy protected CDs, which do
not comply with international audio
CD standards (Red Book), may not
play on your car audio. Please note
that inabilities to properly play a
copy protected CD may indicate
that the CD is defective, not the CD
player.
NOTE:
Order of playing files (folders) :
1. Song playing order : to sequentially.
2. Folder playing order :❋ If no song file is contained in
the folder, that folder is not dis-
played.

CAUTION
Operating the device whilst
driving could lead to acci-dents due to a lack of atten- tion to external surroundings.First park the vehicle beforeoperating the device.
Adjust the volume to levels that allow the driver to hearsounds from outside of thevehicle. Driving in a statewhere external sounds cannot be heard may lead to acci-dents.
Pay attention to the volume setting when turning thedevice on. A sudden output of extreme volume upon turningthe device on could lead tohearing impairment. (Adjust the volume to a suitable levelsbefore turning off the device.)

WARNING
Do not stare at the screen whilst driving. Staring at the
screen for prolonged periodsof time could lead to trafficaccidents.
Do not disassemble, assem- ble, or modify the audio sys-
tem. Such acts could result in
accidents, fire, or electric
shock.
Using the phone whilst driv- ing may lead to a lack of atten-tion of traffic conditions andincrease the likelihood of
accidents. Use the phone fea-
ture after parking the vehicle.
Heed caution not to spill water or introduce foreign objects
into the device. Such acts
could lead to smoke, fire, or
product malfunction.
(Continued)(Continued)
Please refrain from use if thescreen is blank or no sound
can be heard as these signs
may indicate product malfunc-
tion. Continued use in suchconditions could lead to acci-
dents(fires, electric shock) or
product malfunctions.
Do not touch the antenna dur- ing thunder or lightening as
such acts may lead to light-
ning induced electric shock.
Do not stop or park in park- ing-restricted areas to operate
the product. Such acts couldlead to traffic accidents.
Use the system with the vehi- cle ignition turned on.
Prolonged use with the igni-tion turned off could result in
battery discharge.
