Caution
Observe the following cautions when using
this unit.
❑ Keep the sound volume at an appropriate level.
Keep the volume level low enough to be aware of road and
traffic conditions while driving.
❑ Do not insert or allow your hand or fingers to be
caught in the unit.
To prevent injury, do not get your hand or fingers caught in
moving parts or in the disc slot. Especially watch out for
infants.
❑ This unit is designed for use exclusively in automobiles.
❑ Do not operate the unit for a prolonged period with
the engine turned off.
Operating the audio system for a long period of time with
the engine turned off will drain the battery.
❑ Do not expose the unit to direct sunlight or excessive heat.
Otherwise these will raise the interior temperature of the
unit, and it may lead to smoke, fire, or other damage to the
unit.
❑ Do not use the product where it will be exposed to
water, moisture, or dust.
Exposure of the unit to water, moisture, or dust may lead
to smoke, fire, or other damage to the unit. Make especially
sure that the unit does not get wet in car washes or on
rainy days.
❑ To ensure safety, never attempt to preset stations
while you are driving.
❑ Depending upon the transmission condition of
electro-magnetic waves, the geographical reasons
and/or the weather conditions, you may not
receive the NOAA radio partially or at all.
❑ Make sure that your weather radio can receive
properly before driving, especially, before use in a
critical condition.
❑ Set the volume level to low enough before the AUX
connection is completed.
Failure to observe this, the loud noise may come out and
damage your speakers and your hearing. Direct connection
of the speaker/headphone output of an external device
without any attenuator may distort sound or damage the
connected external device.
Observe the following cautions when
installing.
❑ Refer wiring and installation to qualified service
personnel.
Installation of this unit requires special skills and experience. For maximum safety, have it installed by your dealer.
Panasonic is not liable for any problems resulting from
your own installation of the unit.
❑ Follow the instructions to install and wire the product.
Not following the instructions to properly install and wire
the product could cause an accident or fire.
❑ Take care not to damage the leads.
When wiring, take care not to damage the leads. Prevent
them from getting caught in the vehicle chassis, screws,
and moving parts such as seat rails. Do not scratch, pull,
bend or twist the leads. Do not run them near heat sources
or place heavy objects on them. If leads must be run over
sharp metal edges, protect the leads by winding them with
vinyl tape or similar protection.
❑ Use the designated parts and tools for installation.
Use the supplied or designated parts and appropriate tools
to install the product. The use of parts other than those
supplied or designated may result in internal damage to the
unit. Faulty installation may lead to an accident, a malfunction or fire.
❑ Do not block the air vent or the cooling plate of the
unit.
Blocking these parts will cause the interior of the unit to
overheat and will result in fire or other damage.
❑ Do not install the product where it is exposed to
strong vibrations or is unstable.
Avoid slanted or strongly curved surfaces for installation. If
the installation is not stable, the unit may fall down while
driving and this can lead to an accident or injury.

with the front end up at a convenient angle, but not more
than 30˚.
The user should bear in mind that in some areas there may
be restrictions on how and where this unit must be
installed. Consult your dealer for further details.
❑ Wear gloves for safety. Make sure that wiring is
completed before installation.
❑ To prevent damage to the unit, do not connect the
power connector until the whole wiring is completed.

for high quality sounds.
¡ Selecting VBR (Variable Bit Rate) is not recommended
because playing time is not displayed properly and sound
may be skipped.
¡ The playback sound quality differs depending on the encoding
circumstances. For details, refer to the user manual of your
own encoding software and writing software.
¡ Be sure to put an extension compatible with the format.
¡ It is recommended to set the bit rate to “128 kbps or more”
and “fixed”.

Cautions as to compressed audio files
Compressed audio file writing
¡ Do not save an audio file (CD-DA file) and a compressed
audio file on the same disc. Failure to observe this may
result in difficulty in playing.
¡ If compressed audio files formatted with two or more types
are saved on the same disc, each format shall have a different folder.
¡ Do not write files other than compressed audio files.
¡ Playability may depend on the combination of writing software and disc writer to be used.
¡ This unit does not support the play list function.
¡ Write files in a disc-at-once manner unless otherwise needed.
¡ You can shorten the duration between data read and playback
by decreasing the quantity of files or folders, or the depth of
the hierarchy.
Supported file systems
■ CD-media
ISO 9660 Level 1/Level 2, Apple Extension to ISO 9660,

CD-media: 999
USB device: 65 535
¡ Maximum number of files in one folder
CD-media: 255
USB device: 999
¡ Maximum depth of trees: 8
¡ Maximum number of folders: 255 (Root folder is included.)
Notes:
¡ This unit counts the number of folders irrespective of the
presence or absence of a compressed audio file.
¡ If the selected folder does not contain any compressed audio
file, the nearest compressed audio file in the order of playback
will play.
¡ Playback order of this unit may be different from that of other
compressed audio players even if the same disc is used
¡ “ROOT” appears when displaying the root folder name.

Notes on Discs
How to hold the disc
Disc insert
¡Do not touch the underside of the disc.
¡Do not scratch the disc.
¡Do not bend disc.
¡When not in use, keep disc in the case.
Printed side
Unusable discs
Do not use discs that fit any of the descriptions given
below. Using these discs may damage the discs or
cause the unit to malfunction.
¡Special discs in a shape which is not round
¡Partly or wholly transparent disc
Wholly transparent disc*
Partly transparent disc
The surfaces of new discs tend to be slippery. Therefore,
when using such a disc for the first time, it may not load
satisfactorily even when it has been inserted into the unit.
At a time like this, insert the disc into the unit as far as it
will go until it is loaded properly.
¡When inserting a disc into or ejecting and removing it
from the unit, insert it straight in or eject and remove
it straight out in parallel with the unit. Otherwise, the
disc may be scratched or marked in the process.
¡When inserting a disc, do not put one disc on another.
Failure to observe this may cause the discs to be
jammed.
Do not leave discs in the following places:
¡Direct sunlight
¡Near car heaters
¡Dirty, dusty and damp areas
¡On seats and dashboards
Disc cleaning
Use a dry, soft cloth to wipe from the center outward.
Do not attach any seals or labels to your discs.
Do not write on the disc label in a heavy pen or ballpoint
pen.
*Wholly semi-transparent disc may not be played back.
¡Discs with adhered labels, etc. on them
<Correct>
Disc with adhered stickers
or tape
Labels created by a printer
Protective films or sheets
Disc accessories (stabilizers, etc.)
¡Damaged or deformed discs
Shoddily made discs
Discs with cracks,
scratches or parts missing
<Wrong>
Notes on CD-Rs/RWs
¡You may have trouble playing back some CD-R/RW
discs recorded on CD recorders (CD-R/RW drives),
either due to their recording characteristics or dirt, fingerprints, scratches, etc. on the disc surface.
¡CD-R/RW discs are less resistant to high temperatures
and high humidity than ordinary music CDs. Leaving
them inside a car for extended periods may damage and
make playback impossible.
¡The unit may not successfully playback a CD-R/RW that
was made by the combination of writing software, a CD
recorder (CD-R/RW drives) and a disc if they are incompatible with one another.
¡This player does not play CD-R/RW discs if the session
is not closed.
¡Be sure to observe the handling instructions of CDR/RW discs.
¡This player does not play CD-R/RW discs which contain
other than CD-DA or MP3/WMA data.
Discs with burrs
Please remove the burrs
before use.
