Caution!
The disc rotates at high speed in the drive unit.
Use of worn, damaged, or non-standard CD-ROM discs
can only adversely affect the drive and cause the disc to
shatter or crush while in use.
Disc crush can only occur when you use a damaged
CD-ROM disc in the drive. It is an extremely rare occurrence,
but there are steps which can be taken to prevent it.
Always check your discs before inserting
them into the drive.
1. Take care not to use worn, cracked, damaged,
warped or poor quality CD-ROMs, as this may
cause damage to your drive.
2. Check the clear plastic on the center of the disc,
cracks here are the main cause of disc crush.
3. Do not play CD-ROMs which are a non-standard (I.e.
non-circular)shape, such as heart shaped discs, or
discs in the shape of a business card.
How can you keep your discs from becoming
damaged?
1. When not in use, remove discs from the drive.
2. Keep discs in the packaging supplied with them
and out of direct sunlight and away from heat
sources.
Excessive vibration or a sudden jolt to the drive during
operation may cause a malfunction.
Avoid exposing the drive to sudden changes in temperature
as it may cause condensation to collect inside the drive.
