ATTENTION
Static discharges may cause permanent damage to the
module. Follow these guidelines when you handle the
module:
• Touch a grounded object to discharge static potential.
• Wear an approved wrist strap grounding device.
• Handle module by plastic case only. Avoid contact
between module circuits and any surface which can
hold an electrostatic charge.
• If available, use a static-safe work station.
