I Handling of discs
Heed the following notes on handling of discs not to create any
cause for a recording failure, a loss of the recorded data, or a
malfunction of this unit.
• This compact disc recorder is designed for use with CDs
(including 8cm [3"] discs) bearing the
marks only. Never attempt to load any other type of disc into this
unit.
• CDs are not subjected to wear during play. However if the disc is
handled improperly, damage may be created on the disc to
adversely affect the disc's play.
• Do not use cleaning discs or warped discs. All of these could
damage this unit.
• Although playback of CDs is generally not affected by small
particles of dust or fingerprints on their playing surface, dust,
fingerprints, small scratches and direct sunlight on the recording
surface of a CD-R or CD-RW disc may make recording
impossible. Therefore, for optimal performance of the recorder
and for long-term enjoyment of your CD collection, handle discs
correctly as outlined in the following guidelines.
1. Hold discs by touching only the edges or center hole.
2. When a disc is not currently being used, remove it from the
recorder and store in an appropriate case.
3. With proper disc maintenance, cleaning should not be
necessary. However, should cleaning be required, wipe by
using a clean, dry cloth. Do not wipe with a circular motion;
wipe straight outward from the center.
• Do not try to clean the disc's surface by using any type of disc
cleaner, record spray, antistatic spray or liquid, or any other
chemical-based liquid, because such substances might irreparably
damage the disc's surface.
• Do not expose discs to direct sunlight, high temperature, or high
humidity for a long period of time, because this might warp or
otherwise damage the disc.
No!
