Maintaining the Drive
Use the following instructions to clean your drive and CDs:
Cleaning the Surface of the CD-ROM Drive: Lightly wipe the
CD-ROM drive with a dry soft cloth. If stains remain on the
surface, use a damp cloth (soak cloth in a diluted mild detergent
and squeeze it firmly). Do not use solvents such as thinner,
alcohol, and benzene. They cause deformation and discoloration.
Cleaning the Lens: If the lens is dirty, the CD-ROM drive might
not operate correctly. Clean the lens with a CD lens cleaner
(available at stores).
Cleaning the CD: Clean the CD with a soft cloth from the center
to the outside radially. If stains remain on the disk, clean it with
a damp cloth (soak cloth in water and squeeze it firmly). Then,
wipe the disk with a dry soft cloth. Do not use record cleaner or
antistatic spray.
