Baumatic BF13 Instruction Manual page 10

This course of operation has to take place within a period of 10 seconds, no other key than described above may be operated.
Otherwise the input will be interrupted because of incompleteness, the cooktop will not be locked then.
The electronic control remains in a locked condition until it gets unlocked, even if the control has been switched-OFF and -ON
in the meantime. Also a reset of the control (after a voltage drop) does not cancel the key lock.
Unlocking for cooking purposes:
To unlock and operate the control it is required to operate the front right cooking-zone-select-key and the MINUS-key (4)
simultaneously. "L" (LOCKED) in the display extinguishes and all cooking zones show "0" with a blinking dot. Should a
cooking zone be "hot", "H" is displayed instead of the static "0". After switching-OFF the control, the child safety feature is
active again.
Cancelling the key lock:
After switching-ON the control the child safety feature can be deactivated. Here it is necessary to simultaneously operate the
front right cooking-zone-select-key and the MINUS-key and then operate the MINUS-key alone. If all steps have been carried
out in the right order within 10 seconds the key lock gets cancelled and the control is OFF. Otherwise the input will be
considered incomplete, the control remains locked and switches-OFF after 20 seconds.
After a renewed switching-ON by means of the ON/OFF key all displays show „0", the display dots are blinking and the
control is ready for cooking. If a cooking zone is "hot" , "H" will be displayed instead of the static „0".
