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 internal
components.
u
Unplug the unit from AC power before servicing any electronic component inside the
chassis.
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.
