On Cleaning CD-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 140
°
F (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 50
°
F and 80
°

the battery pack may be reaching the end of its life and should be
replaced.
