On handling CD-ROMs
Do not touch the surface of the disc.
Do not drop or bend the disc.
Fingerprints and dust on the surface of a disc may cause read errors. Always hold the disc by its edge and
its central hole, as shown:
Proper care of the disc is essential to its continuous reliability. Do not use solvents such as benzine,
thinning agents, 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 the battery pack
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.
