4.2 Emergency power supply
There is an emergency power supply facility on the keyboard, in case the fitted battery becomes completely
discharged. While holding a 9-volt block battery firmly against the '+' and '-', carry out the normal opening
procedure. Then you can replace the empty battery.
Do you have questions about your safe, the electronic lock or is there an unexpected malfunction?
Please contact your local dealer.
