Backup Battery (SF-3100T only)
The battery maintains the setup configuration and messages when a power failure occurs or
when power is accidentally disconnected.
We recommend you use an alkaline battery because it lasts longer than a conventional battery.
The battery can maintain the internal memory for about 20 hours. If the backup battery is
weak or missing, the LCD displays a warning message.
WARNING! Do not unplug the power cord if you’ve already connected it or you will lose all
the messages recorded.
Before installing the battery in the battery compartment, disconnect the telephone line cord
from the TEL. LINE jack.
