ESD Safety Information

Electrostatic discharge (ESD) can damage components of the module.
ESD, which occurs when the module is improperly handled, can cause
complete or intermittent failures.
CAUTION: To prevent ESD-related damage:
Always wear an ESD wrist strap (not provided) when you handle a
module, ensuring that the strap makes good skin contact and is
properly grounded.
Keep the module in its antistatic bag until you are ready to install it.
