On Cleaning CD-ROM and DVD-ROM Disks
Fingerprints and dust on the surface of a disk may cause read errors. Proper care
of the disk 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 disk.
For normal cleaning, hold the disk by its edge and use a soft cloth to wipe the
surface from the center out.
If the disk is badly soiled, moisten a soft cloth with water, wring it out well, and
use it to wipe the surface of the disk 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.
