Backup Battery
Charging
The QC200 utilizes an internal battery to maintain system configuration set-
tings during power interruptions. A battery circuit charges this backup battery
during periods of normal operation.
When the QC200 is used on a daily basis, the backup battery will be adequately
charged to maintain configuration settings during power outages. However,
over extended periods of nonuse, the battery might lose the charge necessary to
maintain configuration settings. To keep the backup battery charged over ex-
tended periods of nonuse, apply power to the QC200 and leave it turned on for
a minimum of 2 days each month.
