The Five Basic Parts
1.1 The System Unit
1.1.3 Inside the System Unit
Occasionally you may need to get inside of your system unit–to add optional
modules, for example, or to upgrade your system. The components in the
system unit are delicate and can be damaged by the static electricity conducted
by your body. Digital provides an antistatic wrist strap to ensure that this
static discharge does not cause damage. Wear the antistatic wrist strap
whenever you touch anything inside the system unit or any item stored in an
antistatic bag. To use the wrist strap, follow the directions on the envelope it
comes in.
