Following messages are safety reminders on how to protect your systems from
damages. And thus, helps you lengthen the life cycle of the system.
1. Check the Line Voltage
a. The operating voltage for the power supply should cover the range of
100VAC-240VAC, otherwise the system may be damaged.
2. Environmental Conditions
a. Place your PPC on a sturdy, level surface. Be sure to allow enough room
on each side to have easy access.
b. Avoid extremely hot or cold places to install your PPC.
c. Avoid exposure to sunlight for a long period of time (for example in a
closed car in summer time. Also avoid the system from any heating
device.). Or do not use PPC when it's been left outdoors in a cold winter
day.
d. Bear in mind that the operating ambient temperature is from 0 C up to
+40 C.
e. Avoid moving the system rapidly from a hot place to a cold place or vice
versa because condensation may come from inside of the system.
f. Place PPC against strong vibrations, which may cause hard disk failure.
g. Do not place the system too close to any radio active device. Radioactive
device may cause interference.
3. Handling
a. Avoid putting heavy objects on top of the system.
b. Do not turn the system upside down. This may cause the floppy drive
and hard drive to mal-function.
c. Do not remove the diskette from the Floppy drive while the light is still
on. If you remove the diskette while the light is on, you may damage
the information on the diskette.
4. Good Care
a. When the outside of the case is stained, remove the stain with neutral
washing agent with a dry cloth.
b. Never use strong agents such as benzene and thinner to clean the system.
c. If heavy stains are present, moisten a cloth with diluted neutral washing
agent or with alcohol and then wipe thoroughly with a dry cloth.

made vacuum cleaner for computers.
