Safety Precaution - Static Electricity
Static electricity can cause bodily harm or damage electronic devices. To avoid dam -
age, keep static-sensitive devices in the static-protective packaging until the installa -
tion period. The following guidelines are also recommended:

Wear a grounded wrist or ankle strap and use gloves to prevent direct contact to
the device before servicing the device. Avoid nylon gloves or work clothes,
which tend to build up a charge.

Always disconnect the power from the device before servicing it.

Before plugging a cable into any port, discharge the voltage stored on the cable
by touching the electrical contacts to the ground surface.
