Storing the Stations (PRESET)
Favorite stations can be tuned by
one touch operation if they are
stored in the Preset buttons.
A maximum of 30 stations can be
saved. 12 in AM (six each for
AM1 and AM2.), and 18 in FM (six
each for FM1, FM2 and FM3.) 1. Select the radio mode to be stored from FM1, FM2, FM3,
AM1 or AM2. 2. Tune in the station of your
choice.
3. Press and hold down the Preset buttons you want to
store in, for more than
two seconds. When the station

Radio Reception
Usually, a problem with radio
reception does not mean there is a
problem with your radio. It is just the
normal result of conditions outside
the vehicle. For example, nearby
buildings and terrain can interfere
with FM reception. Power lines or
telephone wires can interfere with
AM signals.
And of course, radio signals have a
limited range. The farther you are
from a station, the weaker its signal
will be. In addition, reception
conditions change constantly as
your vehicle moves. Here are some common reception
problems that probably do not
indicate a problem with your radio.
FM Transmissions
Fading and drifting stations -
Generally, the effective range of FM
is about 40 km (25 miles). Once
outside this range, you may notice
fading and drifting, which increase
with the distance from the radio
transmitter. They are often
accompanied by distortion.
Multi-path - FM signals are
reflective, making it possible for two
signals to reach your antenna at the
same time. If this happens, the
signals will cancel each other out,
causing a momentary 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
you are listening to is interrupted or
weakened, and there is another
strong station nearby on the FM

band, your radio may tune in the
second station until the original
signal can be picked up again.
AM Transmissions
Fading - AM broadcasts are
reflected by the upper atmosphere,
especially at night. These reflected
signals can interfere with those
received directly from the radio
station, causing the radio station to
sound alternately strong and weak.
Station interference - When a
reflected signal and a signal
received directly from a radio station
are very nearly the same frequency,
they can interfere with each other,
making it difficult to hear the
broadcast.
Static - AM is easily affected by
external sources of electrical noise,
such as high tension power lines,
lightning, or electrical motors. This
results in static.

Using the Compact Disc
System
Disc
When it is cold or when it is raining,
the car windows will fog up and
cause dew (water drops) to form in
the vehicle compartment
(condensation). When this happens,
the audio may skip, and playback
will stop. Ventilate the vehicle
compartment and dehumidify before
resuming use. The audio may skip due to violent
vibrations when the car is traveling
across harsh roads.
Never insert foreign objects into the
disc insertion slot.
Do not insert a wet disc into the
player.
This player uses an invisible laser
beam which could cause hazardous
radiation exposure if directed
outside the player. Be sure to
operate the player correctly.
Playback may not be possible due
to recording conditions or disc
characteristics, scratches, dirt,
or deterioration.
Usable Discs
Music CDs with the following marks
can be used. CD-R and CD-RW
discs recorded according to the
CD-DA format can also be played.
.
CD-R (CD-Recordable), CD-RW

also not be played accurately.
This device accepts 8 cm (3 in)
CD. Plug in the device directly
without using an adapter, etc. to
avoid damage.
When Removing a Disc
Do not leave discs inside the player
or partially inserted for a long time.
This may scratch the discs and
make them unusable.
Remove the disc horizontally from
the main device. Do not pull it
violently towards the top.
Also do not pull it down hard while
removing. The disc may become
damaged and the audio may skip.
Do not insert objects other than
discs into the disc slot or insert
more than one disc at a time.
Handling a Disc
Avoid exposing the disc to direct
sunlight and always keep it in a
case. Otherwise, the disc will bend
and become unusable. Do not stick any paper tape to the
recording side or the label side as it
may lead the disc to malfunction.
Do not use a disc with cracks or if it
is severely bent as it may lead to
damage.
Hold the disc without touching the
recording side as this may make the
disc dirty and lead to the audio
skipping.
Using benzene, record disc cleaner,
or anti-static fluids may damage the
disc. Using a dirty disc will damage
the disc and lead to audio skipping.
When the disc is dirty, use a
commercial disc cleaner to gently
clean it from the inside to the
outside. Do not use lens cleaner.
Do not use the types of disc
described below because such
discs may cause a breakdown.

ID3 Tag/WMA Tag
MP3/WMA files have an ID3 Tag/
WMA Tag that allows the input of
information so that data such as
song title and artist can be saved.
This deck supports ID3 Ver. 1.0, 1.1,
2.2, 2.3 and WMA tags.
Media
Media such as CD-R and CD-RW
discs are capable of playing MP3/
WMA files. Compared to the
CD-ROM media commonly used for
music discs, CD-R and CD-RW
discs are easily damaged in high
temperature/high humidity
environments and part of the CD-R
and CD-RW may become incapable
of playback. Fingerprints or
scratches on the disc may prevent
playback or cause skipping during
playback. Sections of a CD-R or
CD-RW may deteriorate if it is left
inside a vehicle for long periods of time. It is also recommended that
CD-R and CD-RW discs be kept in
a light-resistant case because the
discs are vulnerable to ultra-violet
light.
Format of Discs
The format of discs to be used must
be ISO 9660 Level 1 or Level 2.
Control items for this standard are
as follows:
.
Maximum directory layers:
8 layers
. Maximum characters for folder
names/file names: 48 (including
“_”and 3 letter file extension)
. Maximum number of folders:
192 (including the root folder)
. Maximum number of files per
disc: 255
A root directory is counted as one
folder.
File Names
Only files with the MP3/WMA file
extension mp3, .wma can be
recognized as MP3/WMA and
played. Be sure to save MP3 files

Infotainment System 109
with the mp3 file extension. Be sure
to use the .wma file extension when
saving WMA files. The MP letters of
the file extension will be recognized
whether entered as uppercase
letters or lowercase letters.
If the .mp3 or .wma file extension is
attached to a file other than an MP3/
WMA file, that file will be mistakenly
recognized by the deck as an MP3/
WMA file and played, resulting in
loud noise output that can damage
the speakers. Be sure to avoid
attaching the mp3 or .wma file
extension to files that are not MP3/
WMA files.
Multi-Sessions
Does not support multi-session.
When the disc used is a
multi-session disc, only the first
session will be played.
Playing MP3/WMA
When a disc with recorded MP3/
WMA files is inserted, the deck first
checks all the files on the disc. No
sound is emitted while the deck is
checking the files on the disc. It is
recommended that the disc shouldbe recorded without files other than
MP3/WMA files and without
unnecessary folders in order to
speed up the checking of disc files
by the deck.
MP3/WMA Playing Time Display
It is possible that playing time will
not be correct, depending on the
writing condition of the MP3/WMA
file or when VBR Fast Up/Down is
operated.
Display Order of MP3/WMA File/
Folder Names
Names of MP3/WMA folders and
files within the same level are
displayed in the following order.
1. MP3/WMA folders displayed first, by ascending order of
numbers, letters. The files
stored just below the root of the
disc will be stored in the ROOT
FOLDER.
2. Files displayed next, by ascending order of numbers,
letters. It is assumed here that
a disc has already been loaded
into the unit. When a disc is inserted, the CD
player screen will be displayed for
about a few seconds while the unit
checks whether the CD is an audio
CD or whether it contains MP3/
WMA data.
Normally, tracks in ROOT FOLDER
will be played in order from the
first file.
