CD-RW(multiple recording)

CD-RW discs are able to be recorded onto many times but will only playback in CD players offering CD-RW compatibility. Products that offer CD-RW compatibility are available from Marantz, Marantz Professional, and Superscope. Please contact your dealer for more information on these products.

Notes:

•Some DVD players cannot playback CD-R discs and CD-RW discs because of laser power differ- ences.

•Some CD players may be able to playback finalized CD-RW discs.

•Some CD players can not play finalized CD-R discs because of the low reflectivity of such discs.

Which discs to use:

The CDR300 is able to record onto any 1X or 2X compatible CD-R and CD-RW disc, including discs for Consumer use and Professional (computer) discs.

The CDR300 records according to the Orange Book specification. Every CDR disc sold should be accord- ing to the Orange Book specification and therefore compatible with the CDR300.

In practice however, the quality of the recording depends on the match between the disc used and the writing strategy of the recorder. At 1X speed (stand alone audio) the match between disc and recorder is

important. Higher recording speeds are less critical in terms of recording quality.

Consumer CD Recorders can only record on CD-R Audio discs and those discs are optimized for single speed automatically. Professional CD Recorders can use both Audio and Data discs. When using Data discs, one should take care to use discs with a good single speed compatibility.

Recording Capacity:

Discs with higher capacity than 74 minutes (80 min- utes) are out of the Orange Book standard and may perform below your expectations.

Compact disc care

The glossy side is the record side of the disc, and matted (dull) side is the label side.

Handle discs carefully so as not to damage or scratch the record side.

Avoid placing discs in the following locations:

•In direct sunlight or near a source of heat such as a heater.

•In a place that is damp or dirty.

•In a place which could be exposed to rain, such as near a window.
