Electrostatic Discharge
ATTENTION: Electrostatic discharge can degrade
performance or damage the module.
Electrostatic discharge can damage integrated circuits or semiconductors in
the scanner if you touch backplane connector pins. It can also damage the
scanner when you set configuration plugs and/or switches inside the
module. Avoid electrostatic damage by observing the following
precautions:
Touch a grounded object to rid yourself of charge before handling the
module.
Do not touch the backplane connector or connector pins.
When not in use, keep the module in its static shield bag.
