Safety precautions G Warning! The single CD player and the CD changer are classified as a Class 1 laser product. You must not open the casing. There is a risk of exposure to invisible laser radiation if you open the casing, or if the casing is faulty or damaged. The single CD player and the CD changer do not contain any parts that you are able to maintain yourself. For safety reasons, all maintenance work must be carried out by qualified technicians. G Warning! In order to avoid distraction which could lead to an accident, the driver should insert or eject CDs with the vehicle at a standstill and operate the audio system only if permitted by road, weather and traffic conditions. Bear in mind that at a speed of just 30 mph (approximately 50 km/h), your vehicle is covering a distance of 44 feet (approximately 14 m) every second.

General notes i Audio CDs with copy protection are not compatible with the CD audio standard and therefore may not be able to be played by the single CD player and/or the CD changer. There may be playback problems when playing copied discs. There is a large variety of discs, disc-writing software and writers available. This variety means that there is no guarantee that the system will be able to play discs that you have written/copied yourself. There may be playback problems if you use CD-R or CD-RW type discs you have compiled yourself with a storage capacity of more than 700 MB. These CDs are not compatible with currently applicable standards.

! Do not affix stickers or labels to the CDs, they can become warped due to the heat that develops in the CD drive or CD changer. In certain situations, the CDs can then no longer be ejected and cause damage to the drive. Such damage is not covered by the Mercedes-Benz Limited Warranty.

! Your CD drive or CD changer has been

designed to play CDs which correspond to the IEC 60908 standard. You can therefore only use CDs with a maximum thickness of 1.3 mm. If you insert thicker discs, e.g. ones that have data on both sides (one side with DVD data, the other side with audio data), they cannot be ejected and will damage the drive.

Do not use CDs with a diameter of 8 cm. Attempting to play CDs with a diameter of 8 cm or playing such CDs with an adapter may cause damage to the CD drive. Such damage is not covered by the Mercedes-Benz Limited Warranty. Only use round discs with a diameter of 12 cm. Should excessively high or low temperatures occur while in CD changer mode, a message will appear in the display, and the CD will be muted until the temperature has reached an acceptable level for the system to continue operation. Tips on handling CDs ROnly touch the CDs at the edges. RHandle CDs carefully to prevent

interference during playback.

RAvoid scratches, fingerprints and dust on

the CDs.

RThe CDs must only be labeled using pens

specially designed for this purpose. RClean CDs from time to time with a

commercially available cleaning cloth. Never wipe the CD in a circular motion;

Audio system 159

instead, wipe it in a straight line starting in the center and moving outward. Do not use solvents, anti-static sprays, etc. for cleaning.

RReplace the CD in its case after use. RProtect CDs from heat and direct sunlight.

Notes about MP3 mode The single CD player and the CD changer can play audio CDs as well as CDs with MP3/ WMA files. i Due to the branched data structure,

playback of the first track may be delayed slightly.

Permissible media for MP3/WMA files RCD-R RCD-RW

Permissible file systems RISO9660/Joliet for CDs

Multisession CDs For multisession CDs, the first session type of the CD determines how the audio system will process the CD. For example, if the first session type is according to the audio CD standard and the second session type is according to the data CD standard containing MP3/WMA tracks, the audio system will treat the CD as a conventional audio CD. This means that it is only possible to access the audio CD tracks. Access to the MP3/WMA tracks is not possible. Similarly, if the first session type is according to the data CD standard containing MP3/ WMA tracks and the second session type is according to the audio CD standard, the audio system will treat the CD as a data CD. This means that it is only possible to access the MP3/WMA tracks. Access to the audio CD tracks is not possible.

Version: 2.11.8.1

File structure on a disc When you create an MP3/WMA disc, the MP3/WMA tracks can be organized in folders. A folder can also contain other folders. A disc can contain a maximum of 255 folders. A folder can contain a maximum of 255 tracks and 255 subfolders. A data medium may contain a maximum of 500 tracks. The directory depth may not exceed a maximum of 8 levels. The system will ignore files in lower levels. Track and folder names When you create an MP3/WMA disc, you can assign names to the MP3/WMA tracks and folders. The audio system uses these names for the corresponding display in MP3 mode. Empty folders or folders which contain data other than MP3/WMA tracks are not displayed by the audio system. If MP3/WMA files are saved in the root directory itself (uppermost directory on storage medium), the root directory will also be treated as a folder. The audio system will then show the name of the root directory as the folder name. You must observe the following when assigning track names: RTrack names must have at least one

character.

RTrack names must have the extension

“mp3” or “wma”.

RThere must be a period between the track

name and the extension. Example of a correct track name: Track1.mp3

The audio system is unable to recognize an MP3/WMA track if Rthere is no period between the track title

and the extension

Rthere is no extension

i The audio system does not support ID3

tags.

Supported file formats Supported file formats are: RMP3
RWMA i If music files of file formats other than

MP3 are stored together with MP3 files on one disc, the loading process may take longer.

Permissible MP3 formats The audio system supports the MPEG1 Audio Layer 3 format. i This format is generally known as “MP3”. Permissible bit and sampling rates are: Rfixed and variable bit rates up to

320 kbit/s

RSampling rates of 24 kHz – 48 kHz i Only use MP3 tracks with a bit rate of at least 128 kbit/s or higher and a sampling rate of at least 44.1 kHz or higher. Smaller rates can cause a noticeable deterioration in sound quality. This is especially the case if you have the surround sound function activated.

WMA (Windows Media® Audio) Windows Media® Audio (WMA) is an audio data compression technology developed by Microsoft®. The audio system supports the following types of audio files: Rfixed bit rates of 5 kbit/s up to

384 kbit/s

RSampling rates from 8 kHz to 48 kHz The audio system does not support the following WMA files: RDRM (Digital Rights Management) coded

files

Rvariable bit rates
