Handling Precautions
Warning:
1. Static electricity may cause damage to the integrated circuits on
the motherboard. Before handling any motherboard outside of its
protective packaging, ensure that there is no static electric charge
in your body.
2. There is a danger of explosion if the battery is incorrectly
replaced. Replace only with the same or an equivalent type
recommended by the manufacturer.
3. Discard used batteries according to the manufacturer’s
instructions.
4. Never run the processor without the heatsink properly and firmly
attached. PERMANENT DAMAGE WILL RESULT!
Observe the following basic precautions when handling the motherboard
or other computer components:
nWear a static wrist strap which fits around your wrist and is
connected to a natural earth ground.
nTouch a grounded or anti-static surface or a metal fixture such as a
water pipe.
nAvoid contacting the components on add-on cards, motherboards,
and modules with the golden fingers connectors plugged into the
expansion slot. It is best to handle system components by their
monting brackets.
The above methods prevent static build-up and cause it to be discharged
properly.
