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 auto-

mobiles.

❑ 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 exces-

sive 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.

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.

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

Disc insert

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.

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 CD-

R/RW discs.

¡This player does not play CD-R/RW discs which contain other than CD-DA or MP3/WMA data.
