1.4 Safety Precautions
Before using this system, read the following information carefully to protect your
system from damages, and extend the life cycle of the system.
1. Check the Line Voltage
•The operating voltage for the power supply should be within the range of
100V to 240V AC; otherwise, the system may be damaged.
2. Environmental Conditions
•Place your PA-J581 on a sturdy, level surface. Be sure to allow enough
space around the system to have easy access needs.
•Avoid installing your PA-J581 POS system in extremely hot or cold places.
•Avoid direct sunlight exposure 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 PA-J581 when it has been left outdoors in a cold winter day.
•Avoid moving the system rapidly from a hot place to a cold place, and vice
versa, because condensation may occur inside the system.
•Protect your PA-J581 from strong vibrations which may cause hard disk
failure.
•Do not place the system too close to any radio-active device. Radio-active
device may cause signal interference.
•Always shut down the operation system before you turn off the power.
3. Handling
•Avoid placing heavy objects on the top of the system.
•Do not turn the system upside down. This may cause the hard drive to
malfunction.
•Do not allow any objects to fall into this device.
•If water or other liquid spills into the device, unplug the power cord
immediately.
4. Good Care
•When the outside case gets stained, remove the stains using neutral washing
agent with a dry cloth.
•Never use strong agents such as benzene and thinner to clean the surface of
the case.
•If heavy stains are present, moisten a cloth with diluted neutral washing
agent or alcohol and then wipe thoroughly with a dry cloth.
•If dust is accumulated on the case surface, remove it by using a special
vacuum cleaner for computers.
