Maintenance
Do not use benzene, thinner, or rubbing alcohol. Doing so may adversely affect the sur-
face, e.g., discoloration. In addition, do not use commercially-available household clean-
ers 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 com-
puter, it may cause it to work improperly or be damaged.

contact Panasonic Technical Support. (For more information, refer to the “Operating Instruc-
tions” that come with the Protective Film.)
