How car audio works
AM (MW) and FM radio signals are
broadcast from transmitter towers locat-
ed around your city. They are intercepted
by the radio antenna on your car. This
signal is then received by the radio and
sent to your speakers.
When a strong radio signal has reached
your vehicle the precise engineering of
your audio system ensures the best pos-
sible audio reproduction. However in
some cases the signal coming to your
vehicle may not be strong an clear. This
can be due to factors such as the dis-
tance from the radio station, closeness of
other strong radio stations or the pres-
ence of buildings, bridges or other large
obstructions in the area. AM (MW) broadcasts can be received at
greater distances then FM broadcasts.
This is because AM (MW) radio waves
are transmitted at low frequencies. These
long low radio frequency waves can fol-
low the curvature of the earth rather then
travelling straight out into the atmos-
phere. In addition they curve around
obstructions so that they can provide bet-
ter signal coverage.
FM broadcasts are transmitted at high
frequencies and do not bent to follow the
earth’s surface. Because of this FM
broadcasts begin to fade at short dis-
tances from the station. Also FM signal
are easily affected by buildings, moun-
tains or other obstructions. These can
result in certain listening conditions
which might lead you to believe a prob-
lem exists with your radio. The following
conditions are normal and do not indicate
radio trouble.

Features of your vehicle
 Fading – As your car moves awayfrom the radio station, the signal will
weaken and sound will begin to fade.
When this occurs, we suggest that
you select another stronger station.
 Flutter/Static – Weak FM signal or large obstructions between the trans-
mitter and your radio can disturb the
signal causing static or fluttering nois-
es to occur. Reducing the treble level
may lessen this effect until the distur-
bance clears.  Station Swapping – As a FM signal
weakens, another more powerful sta-tion signal near the same frequency
may begin to play. This is because
your radio is designed to lock onto the
clearest signal. If this occurs, selectanother station with a stronger signal.
 Multi-Path Cancellation - Radio sig- nals being received from several
directions can cause distortion or flut-
tering. This can be caused by a director reflected signal from the same sta-
tion, or by signals from two stations
with close frequencies. If this occurs,select another station until the condi-tion has 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 equipment. This does not meanthat something is wrong with the audio
equipment. In such a case, use the
mobile phone at a place as far as possi-
ble from the audio equipment.

CAUTION
When using a communication sys-
tem such a mobile phone or a radio set inside the vehicle, a separateexternal antenna must be fitted.
When a mobile phone or a radio setis used with an internal antennaalone, it may interfere with the vehi- cles electrical system and adverse-
ly affect safe operation of the vehi- cle.
WARNING
Don’t use a mobile phone when you
are driving. You must stop at a safe
place to use a mobile phone.

Troubleshooting
In rare instances, your Head Unit may not be functioning the way you
expect it to do. Before calling the service department, please read the
operating instructions thoroughly and go through the following check
list; it may be possible to quickly solve the problem malfunction.
General
Status
The operating panel generates some heat.
The volume decreases automati-
cally. The volume can no longerbe increased.
Tuner
Status
“PI search” on the display
Stored radio stations disappearedExplanation / How to check
No error. The unit feels warm.
An integrated safety circuit pre-
vents the temperature in the unit
from exceeding a certain value.
Allow the unit to cool down
(set low volume).
The volume and equalizer is self-
adjusted based on radio signal
intensity and its quality level withinfluence of region and location.
Explanation / How to check
When recall is preset, the PI infor-
mation is not available (due to very
weak signal) or has been changed
(due to different region).
Meanwhilst, check the REG set-
tings in Setup menu.
By switching the FM button, 3 dif-
ferent memory banks (FM1, FM2,
FMA) are able to store 6 differentstations each. Status
Increasing / decreasing volume Bad or no reception of the broad- cast signal The frequency instead of the sta-
tion name is displayed The required station cannot be tuned to using automatic search
No traffic announcements are
switched through (during iPod
®
playback) Explanation / How to check
By switching the AM button, 2 dif-
ferent memory banks (MW, MWA)
are able to store 6 different sta-tions each.
Check SDVC setting (1-5 / off) in
Setup menu.
Check if the antenna is correctly connected.
Check whether the supply volt-
age‘s negative pole (brown cable)
is correctly connected to earth
(vehicle chassis). The unit is tuned to a station that
does not transmit RDS signals or
the transmitter is too weak.
The desired station is too weak.
Set desired station manually
(manual tuning)
Check whether the antenna is completely and correctly connect-ed.
Activate the traffic announcement
by pressing TA button.
