Battery Backup – System Memory
Description
The battery on the CD-CP00-AU retains the Clock/Calendar and Last Number Redial (LNR) buffers for
each station when the CD-CP00-AU encounters a power loss. With a fully charged battery, the settings
are retained for approximately three years.
The system programmed memory (Customer Database) is stored in Nonvolatile Memory and can be
erased only by performing a First Initialization.
For additional storage time, the database and Caller ID History can be copied to the Compact Flash card on the
CD-CP00-AU.
Conditions
The battery on the CD-CP00-AU should be removed during long term storage but must be
installed (protection against loss of power) just before blade installation to provide battery
backup for System Memory.
When fully charged, the battery retains System Memory for approximately three years.
You should replace the CD-CP00-AU battery every three years.
During normal operation, the battery is continually recharged using a built-in charging circuit
from the CD-CP00-AU.
To prevent loss of the Caller ID History, you should save the database before storing the
CD-CP00-AU.
Battery backup on the CD-CP00-AU does not protect the following:
Callback
Off-line Status (for programming system or station assignments)
Repeat Redial
Trunk Queuing/Camp-On
Caller ID History
Default Settings
None
The battery must be installed on the CD-CP00-AU prior to programming a customer database.
