Replacing batteries
The input unit is powered by 3 alkaline AA batteries 1.5 V - LR6 or 3 lithium AA batteries 1.5 V -
FR6.
Keep in mind that batteries must be changed as soon as the symbol "battery low" appears on
the display.
Batteries must be changed latest when the status message "CHANGE BATT" is displayed.
Re-adjust the time and date after replacing the batteries.
After a power interruption (no batteries were inserted or the batteries are empty and the line
voltage is off), the function Freeze was set to OFF, the safe lock system will initialize itself
newly.
The safe lock system behaves as if it were set up according to the procedure cold plugging.
The lock with the lowest serial number becomes the master lock.
To prevent the safe lock system from changing its lock positions, the function Freeze must be
set to ON after connecting the first lock. The current master lock will be saved in the system.
The function Freeze must be set to OFF.
