Safety Precautions
The following safety information and procedures should be followed
whenever working with electronic equipment.
Electrical Safety Precautions
Basic electrical safety precautions should be followed to protect yourself
from harm and the appliance from damage:
• Be aware of the location of the power on/off switch as well as the
room's emergency power-off switch, disconnection switch, or
electrical outlet. If an electrical accident occurs, you can then quickly
cut power to the system.
• Do not work alone when working with high-voltage components.
• Before removing or installing main system components, be sure to
disconnect the power first. Turn off the system before you disconnect
the power cord.
• Use only one hand when working with powered-on electrical
equipment. This is to avoid making a complete circuit, which will
cause electrical shock. Use extreme caution when using metal tools,
which can easily damage any electrical components or circuit boards
they come into contact with.
• Do not use mats designed to decrease electrostatic discharge as
protection from electrical shock. Instead, use rubber mats that have
been specifically designed as electrical insulators.
• The power supply cord must include a grounding plug and must be
plugged into a grounded electrical outlet. Use only the cord supplied
with the appliance.
• The power cord plug cap that plugs into the AC receptacle on the
power supply must be an IEC 320, sheet C13, type female connector.
• If you have to replace the motherboard battery, install it the same way
as the original battery. Make sure that the positive side faces up on
the motherboard. This battery must be replaced only with the same
or an equivalent type recommended by the manufacturer. Dispose of
used batteries according to the manufacturer's instructions.
• Do not open the enclosures of power supplies or CD-ROM to avoid
injury.
