Safety Precautions
Before installing and using the equipment, please read the following
precautions:
Put this equipment on a reliable surface during installation. Dropping it or
letting it fall could cause damage.
The power outlet shall be installed near the equipment and shall be easily
accessible.
Turn off the system power and disconnect the power cord from its source
before making any installation. Be sure both the system and the external
devices are turned OFF. Sudden surge of power could ruin sensitive
components. Make sure the equipment is properly grounded.
When the power is connected, never open the equipment. The equipment
should be opened only by qualified service personnel.
Make sure the voltage of the power source is correct before connecting the
equipment to the power outlet.
Disconnect this equipment from the power before cleaning. Use a damp
cloth. Do not use liquid or spray detergents for cleaning.
Avoid the dusty, humidity and temperature extremes.
Do not place heavy objects on the equipment.
If the equipment is not used for long time, disconnect it from the power to
avoid being damaged by transient over-voltage.
The storage temperature shall be above -20°C and below 80°C.
The computer is provided with a battery-powered real-time clock circuit.
There is a danger of explosion if incorrectly replaced. Replace only with the
same or equivalent type recommended by the manufacturer.
If one of the following situation arises, get the equipment checked be
service personnel:
The power cord or plug is damaged.
Liquid has penetrated into the equipment.
The equipment has been exposed to moisture.
The equipment does not work well or it cannot work according the
user’s manual.
The equipment has been dropped and damaged.
The equipment has obvious signs of breakage.
