Precautions
To avoid personal injury and equipment damage, review the following
guidelines before handling Meridian 1 equipment.
Module covers are not hinged; do not let go of the covers. Lift covers
away from the module and set them out of your work area.
Circuit cards may contain a lithium battery. There is a danger of
explosion if the battery is incorrectly replaced. Do not replace
components on any circuit card; you must replace the entire card.
Dispose of circuit cards according to the manufacturer's instructions.
To avoid damage to circuit cards from static discharge, wear a properly
connected antistatic wrist strap when you work on Meridian 1 equipment. If
a wrist strap is not available, regularly touch one of the bare metal strips in a
module to discharge static. Figure 1 shows the recommended connection
points for the wrist strap and the bare metal strips you should touch.
