Slide the antistatic wrist strap onto your wrist, and then attach the antistatic cable.
Connect the cable to the a bare section of the chassis. Ensure that the metal conductor
bead in the elastic sleeve of the antistatic strap contacts bare skin.
Unplug the unit from AC power before servicing any electronic component inside the chassis.
