On Cleaning CD-ROM and DVD-ROM Discs

❑Fingerprints and dust on the surface of a disc may cause read errors. Proper care of the disc is essential to maintain its reliability. Do not use solvents such as benzine, thinner, commercially available cleaners or anti-static spray, as they may cause damage to the disc.

❑For normal cleaning, hold the disc by its edge and use a soft cloth to wipe the surface from the center out.

❑If the disc is badly soiled, moisten a soft cloth with water, wring it out well, and use it to wipe the surface of the disc from the center out. Wipe off any remaining moisture with a dry soft cloth.

On Using Batteries

❑Never leave the battery pack in temperatures above 60° C, such as in a car parked in the sun or under direct sunlight.

❑Battery life is shorter in a cold environment. This is due to decreased battery efficiency at low temperatures.

❑Charge the batteries at temperatures between 10° C to 30° C. Lower temperatures require a longer charging time.

❑While the battery is in use or being discharged, the battery pack heats up. This is normal and is not cause for concern.

❑Keep the battery pack away from all sources of heat.

❑Keep the battery pack dry.

❑Do not open or try to disassemble the battery pack.

❑Do not expose the battery pack to any mechanical shock.

❑If you are not using the computer for an extended period of time, remove the battery pack from the computer to prevent damage to the battery.
