Handling Static-Sensitive Devices
Some components of the options for your IBM Personal
Computer or IBM Personal Computer XT can be
damaged by static discharges. To prevent such damage,
~
your option may be wrapped in a conductive, anti-static
bag; certain precautions should be taken before
removing the option from its bag.
Hold the option (still wrapped in its anti-static bag) in
one hand. Touch an unpainted metal part of your
system unit (for example, the screws on the rear of the
system unit) with the other hand. This will place your
body, the option, and the system unit at the same
ground potential, preventing an accidental static
discharge.
