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 re-usable antistatic wrist strap when servicing or upgrading the system. Once a
disposable wrist strap is used, it cannot be used again.
u
A re-usable antistatic wrist strap can be attached to any bare metal part of the base unit. The metal
conductor bead in the elastic sleeve of re-usable antistatic straps must contact bare skin.
