NOTICE

To avoid damage to the audio/video system:

Be careful not to spill beverages over the audio/video system.

Do not put anything other than an appropriate discs into the CD changer or DVD changer.

INFORMATION

The use of a cellular phone inside or near the vehicle may cause a noise from the speakers of the audio/video system which you are listening to.

However, this does not indicate a malfunction.

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

Fading and drifting stations — Generally, the effective range of FM is about 25 miles (40 km). 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

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, lightening, or electrical motors. This results in static.

XM

Cargo loaded on the roof luggage carrier, especially metal objects, may adversely affect the reception of XM Satellite Radio.

Alternation or modifications carried out without appropriate authorization may invalidate the user’s right to operate the equipment.

Handle discs carefully, especially when you are inserting them. Hold them on the edge and do not bend them.

Avoid getting fingerprints on them, particularly on the shiny side.

Dirt, scratches, warping, pin holes, or other disc damage could cause the player to skip or to repeat a section of a track. (To see a pin hole, hold the disc up to the light.) Remove discs from the players when you are not using them. Store them in their plastic cases away from moisture, heat, and direct sunlight.

To clean a disc: Wipe it with a soft, lint− free cloth that has been dampened

To clean a disc: Wipe it with a soft, lint− free cloth that has been dampened with water. Wipe in a straight line from the center to the edge of the disc (not in circles).

Dry it with another soft, lint−free cloth. Do not use a conventional record cleaner or anti−static device.

MP3/WMA FILES

MP3 (MPEG Audio Layer 3) and WMA (Windows Media Audio) are audio compression standards.

The MP3/WMA player can play MP3 and WMA files on CD−ROM, CD−R and CD−RW discs.

The unit can play disc recordings compatible with ISO 9660 level 1, 2, (Romeo Joliet) and UDF (2.01 or lower) file system.

When naming an MP3 or WMA file, add the appropriate file extension (.mp3 or .wma).

The MP3/WMA player plays back files with .mp3 or .wma file extensions as MP3 or WMA files. To prevent noise and playback errors, use the appropriate file extensions.

The MP3/WMA player can play only the first session using multi−session compatible CDs.

MP3 player — MP3 files are compatible with the ID3 Tag Ver. 1.0, Ver. 1.1, Ver. 2.2, and Ver. 2.3 formats. The unit cannot display disc title, track title and artist name in other formats.

USB memory — MP3 files are compatible with the ID3 Tag Ver. 1.0, Ver.

1.1, Ver. 2.2, Ver. 2.3 and Ver. 2.4 formats.

The unit cannot display track title and artist name in other formats.

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, artist name.

The emphasis function is available only when playing MP3/WMA files recorded at 32, 44.1 and 48 kHz.

USB memory — It is possible to play up to 999 folders, 255 files per folder or 65,025 files in device.

The order changes depending on the PC and MP3/WMA encoding software you use.

CD−R and CD−RW discs

CD−R/CD−RW discs that have not been subject to the “finalizing process” (a process that allows discs to be played on a conventional CD player) cannot be played.

It may not be possible to play CD− R/CD−RW discs recorded on a music CD recorder or a personal computer because of disc characteristics, scratches or dirt on the disc, or dirt, condensation, etc. on the lens of the unit.

It may not be possible to play discs recorded on a personal computer depending on the application settings and the environment. Record with the correct format. (For details, contact the appropriate application manufacturers of the applications.) CD−R/CD−RW discs may be damaged by direct exposure to sunlight, high temperatures or other storage conditions.

The unit may be unable to play some damaged discs.

If you insert a CD−RW disc into the MP3/WMA player, playback will begin more slowly than with a conventional CD or CD−R disc.

Recordings on CD−R/CD−RW cannot be played using the DDCD (Double Density CD) system.

TERMS

Packet write —

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 written to floppy or hard discs.

ID3 Tag —

This is a method of embedding track−related information in an MP3 file. This embedded information can include the track title, the artist’s name, the album title, the music genre, the year of production, comments and other data. The contents can be freely edited using software with ID3 tag editing functions. Although the tags are restricted to the number of characters, the information can be viewed when the track is played back.

WMA Tag —

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, artist name.

ISO 9660 format —

This is the international standard for the formatting of CD−ROM folders and files.

For the ISO 9660 format, there are two levels of regulations.

Level 1:

The file name is in 8.3 format (8 character file names, with a 3 character file extension.

File names must be composed of one−byte capital letters and numbers. The “_” symbol may also be included.) Level 2:

The file name can have up to 31 characters (including the separation mark “.” and file extension). Each folder must contain fewer than 8 hierarchies.

m3u —

Playlists created using “WINAMP” software have a playlist file extension (.m3u).

MP3 —

MP3 is an audio compression standard determined by a working group (MPEG) of the ISO (International Standard Organization).

MP3 compresses audio data to about 1/10 the size of that on conventional discs.

WMA—

WMA (Windows Media Audio) is an audio compression format developed by Microsoft . It compresses files into a size smaller than that of MP3 files. The decoding formats for WMA files are Ver. 7, 8, and 9.
