CAUTION
• Before starting maintenance work, turn off the PC and all devices connected
to it, and unplug them.
Otherwise, an electric shock may occur.
• Clean the PC using a soft dry cloth. Wipe remaining dirt off using a damp cloth, moistened with
neutral detergent and wrung well. Once the dirt is wiped off, remove the neutral detergent from the
PC with a well-wrung cloth moistened with water. Be careful not to let water enter the PC system.
• Clean the ventholes regularly to prevent dust buildup.
• Do not use solvents. Use neutral detergent only. Otherwise, the PC may be damaged.

use a CD-ROM drive cleaning disc.
