Access modules are intended to be serviced by qualified service personnel only.
Electronic modules can be damaged by static electrical discharge. Before handling
modules, put on an antistatic discharge wrist strap to prevent damage to electronic
components. Place modules in antistatic packing material when transporting or storing.
When working on modules, always place them on an approved antistatic mat that is
electrically grounded.
