CAUTION
Do not use benzene, thinner, or rubbing alcohol. Doing so may adversely affect
the surface, e.g., discoloration. In addition, do not use commercially-available
household cleaners and cosmetics, as they may contain components harmful to
the surface.
Do not directly add or spray water or detergent. If liquid enters the inside of the

them regularly.
We recommend you run the software:

We recommend that you check data received on disks or from external sources, such
as data downloaded from the Internet, e-mail, etc. (For compressed files, uncompress
them before running a check).
