❑
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 centre
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 centre 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.
❑
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.
❑
If, after fully charging the battery pack, the battery power is still low, the battery pack may be reaching
the end of its life and should be replaced.
