Cleaning and Maintenance
• The device, battery, and charger are not water-resistant. Keep them dry. Protect the device,
battery, and charger from water or vapor. Do not touch the device or the charger with a wet
hand. Otherwise, it may lead to a short circuit, a malfunction of the device, and an electric
shock to the user.
• Do not place your device, battery, and charger in places where they can get damaged
because of collision. Otherwise, it may lead to battery leakage, device malfunction,
overheating, fire, or explosion.
• Do not place magnetic storage media such as magnetic cards and floppy disks near the

charger.
• Do not use any chemical detergent, powder, or other chemical agents (such as alcohol and
benzene) to clean the device and the charger. Otherwise, parts of the device may be damaged
or a fire can be caused. You can clean the device and the charger with a piece of damp and
soft antistatic cloth.
