INSTALLATION AND SETUP
Backup Battery (SF3000T 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.
1.Lift the control panel ➀, and open the cartridge compartment cover ➁.
2.Remove the old battery, if necessary. Connect the new battery to the clips.
