files by their “.wma” file extensions.

Always close the session (complete disc creation).
This unit cannot play discs if the session has not
been closed.

Storage precautions
<
Discs should be returned to their cases after use to
avoid dust and scratches that could cause the laser
pickup to “skip.”
<
Do not expose discs to direct sunlight or high-
temperature and humidity for extended periods.
Long exposure to high temperatures will warp
discs.
<
CD-R and CD-RW discs are more sensitive to the
effects of heat and ultraviolet rays than ordinary
CDs. It is important that they are not stored in
locations where they will be exposed to direct
sunlight. They should also be kept away from
sources of heat, such as radiators and heat-
generating electrical devices.
<
Dirt on the disc may cause the sound to skip or
reduce the sound quality. Be sure to keep the discs
clean.
Maintenance
<
If a disc becomes dirty, wipe its surface radially
from the center hole outward towards the outer
edge with a soft, dry cloth.
<
Never clean discs using chemicals such as record
sprays, antistatic sprays and fluids, and thinner.
Such chemicals will do irreparable damage to the
disc’s plastic surface.
