Backup Battery Checkout (Nonrechargeable)
See > Backup Batteries Install Remove
If removing all power sources except for the backup battery
results in the system being reset, suspect a problem with the backup batteries.
Refer to the following:
Note: Make sure either the battery pack is installed or
the AC Adapter is connected.
If the backup batteries are removed and no other power
source is available (AC Adapter or battery pack), the system is reset,
and all the stored data is lost.
