AUDIO CD

CD-R/-RW in AUDIO CD format CD-R/-RW in DATA CD format, containing MP3 audio tracks1) that conforms to ISO 96602) Level 1/ Level 2, Joliet (in expansion format), or Multi Session3)
MP3 (MPEG 1 Audio Layer 3) is a standard format defined by ISO/MPEG which compresses audio data. MP3 audio tracks must be in MPEG 1 Audio Layer 3 format. 2) A logical format of files and folders on CDROMs, defined by ISO (International Organization for Standardization). 3) This is a recording method that enables adding of data using the Track-At-Once method. Conventional discs begin at a disc control area called the Lead-in and end at an area called Lead-out. A Multi Session disc is a disc having multiple sessions, with each segment from Lead-in to Lead-out regarded as a single session.

CD-Extra: This format records audio (AUDIO CD data) on the tracks in session 1 and data on the tracks in session 2. 2) Mixed CD: This format records data on the first track and audio (AUDIO CD data) on the second and subsequent tracks of a session.

Note on DualDiscs

A DualDisc is a two sided disc product which mates DVD recorded material on one side with digital audio material on the other side. However, since the audio material side does not conform to the Compact Disc (CD) standard, playback on this product is not guaranteed.

Note on CD-R/-RW

In some cases, CD-Rs/-RWs cannot be played back on this system due to the recording quality or physical condition of the disc, or the characteristics of the recording device and authoring software. The disc will not be played back if it has not been correctly finalized. For more information, see the operating instructions of the recording device.
Music discs encoded with copyright protection technologies
This product is designed to play back discs that conform to the Compact Disc (CD) standard. Recently, various music discs encoded with copyright protection technologies are marketed by some record companies. Please be aware that among those discs, there are some that do not conform to the CD standard and may not be playable by this product.

On safety
The system is not disconnected from the AC power source (mains) as long as it is connected to the wall socket, even if the system has been turned off. Completely disconnect the power cord (mains lead) from the wall socket (mains) if it is not going to be used for an extended period of time. When unplugging the unit, always grip the plug. Never pull the cord itself. Should any solid object or liquid get into the system, unplug the system, and have it checked by qualified personnel before operating it again. For customers in United States One blade of the plug is wider than other for the purpose of safety and will fit to the wall outlet only one way.

On placement

Do not place the system in an inclined position or in locations that are extremely hot, cold, dusty, dirty, or humid or lacking adequate ventilation, or subject to vibration, direct sunlight or a bright light. Be careful when placing the unit or speakers on surfaces that have been specially treated (for example, with wax, oil, polish) as staining or discoloration of the surface may result. If the system is brought directly from a cold to a warm location or is placed in a very damp room, moisture may condense on the lens inside the system, and cause the system to malfunction. In this situation, remove the disc, and leave the system turned on for about an hour until the moisture evaporates. Do not place anything on top of the tape deck as this may cause a malfunction.
