Note:
The backup times shown here are only an estimate and assume that your battery is fully
charged. If your battery is partially discharged (for example, if it is in the middle of a self-test
or is not yet fully charged), then your backup time will be reduced.

Use this procedure to install and to replace the backup battery.
1.
Press down and pull back on the latch holding the battery door (on the bottom of the
