Avoiding Electrostatic Discharge

Sensitive components inside the base unit can be damaged by static electricity. To protect
against this possibility, take the following precautions when working with the system's
internal components.
u
Touch the bare metal of the base unit to ensure the base unit and your body are at the
same electric potential.
u
Handle all printed circuit boards as little as possible and by the edges only. Leave new
parts in their protective packaging until you install them.
u
Use a disposable or reusable antistatic wrist strap when servicing or upgrading the
system. Once a disposable wrist strap is used, it cannot be used again.
u
A reusable antistatic wrist strap can be attached to any bare metal part of the base unit.
The metal conductor in the elastic sleeve of reusable antistatic straps must contact bare
skin.

Opening the Base Unit
