6. TIPS FOR OPERATING THE AUDIO SYSTEM
1. OPERATING INFORMATION
Fading and drifting stations: Generally, the
effective range of FM is about 25 miles (40
km). Once outside this range, you may no-
tice fading and drifti ng, which increase with
the distance from the radio transmitter.
They are often accompanied by distortion.
Multi-path: FM signals are reflective, mak-
ing it possible for 2 signals to reach the ve-
hicle’s antenna at the same time. If this
happens, the signals will cancel each other
out, causing a momentar y flutter or loss of
reception.
Static and fluttering: These occur when
signals are blocked by buildings, trees or
other large objects. Increasing the bass
level may reduce static and fluttering.
Station swapping: If the FM signal being
listened to is interrupted or weakened, and
there is another str ong station nearby on
the FM band, the radio may tune in the
second station until the original signal can
be picked up again.
NOTICE
● To avoid damage to the audio system:
• Be careful not to spill beverages over
the audio system.
INFORMATION
● The use of a cellular phone inside or
near the vehicle may cause a noise from
the speakers of the audio system which
you are listening to. However, this does
not indicate a malfunction.
RADIO
Usually, a problem with radio reception
does not mean there is a problem with
the radio — it is just the normal result
of conditions outside the vehicle.
For example, nearby buildings and ter-
rain can interfere with FM reception.
Power lines or phone wires can inter-
fere with AM signals. And of course, ra-
dio signals have a limited range. The
farther the vehicle is from a station, the
weaker its signal will be. In addition, re-
ception conditions change constantly
as the vehicle moves.
Here, some common reception prob-
lems that probably do not indicate a
problem with the radio are described.

MP3i (MP3 interactive) and MP3PRO for-
mats are not compatible with the audio
player.
 The player is compatible with VBR (Vari-
able Bit Rate).
 When playing back files recorded as VBR
(Variable Bit Rate) files, the play time will
not be correctly displayed if the fast for-
ward or reverse operations are used.
 It is not possible to check folders that do
not include MP3/WMA/AAC files.
 MP3/WMA/AAC files in folders up to 8 lev-
els deep can be played.
 The order changes depending on the per-
sonal computer and MP3/WMA/AAC
encoding software you use. 
This is a general term that describes the
process of writing data on-demand to CD-
R, etc., in the same way that data is writ-
ten to floppy or hard discs.
 This is a method of embedding track
related information in an MP3 file. This
embedded information can include the
track number, track title, the artist’s name,
the album title, the music genre, the year
of production, comments, cover art and
other data. The contents can be freely
edited using software with ID3 tag editing
functions. Although the tags are restricted
to a number of characters, the information
can be viewed when the track is played
back.
 WMA files can contain a WMA tag that is
used in the same way as an ID3 tag. WMA
tags carry information such as track title
and artist name.
