Module
This section describes how to replace a MERLIN LEGEND MAIL module that is
defective (for example, port 1 or port 2 is defective or the clock battery is bad).

customer's messages, greetings, and programming are not lost.

CAUTION:
Before touching leads, connectors, pins, and other components when
handling the disk drive, use a properly grounded wrist strap to prevent
damage from electrostatic discharge (ESD).

CAUTION:
Although the system is designed for modules to be removed and replaced
without affecting call processing, there is still a possibility that partially
removing or inserting a module can cause a cold start of the MERLIN
LEGEND system.
