Have lamona ceramic hob displaying letter 'f'

SOURCE: have a baumatic ceramic hob displayin letter 'L'

Got the same problem, and remembered I've kept the manual book
L means locked. I dont know how Ive managed to do this as well

Anyway it says:

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 hae been carried out in the right order within 10seconds 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/OFF key all displays show 0", the display dots are blinking and the control is ready for ooking. If a cooking zone is "hot", "H" will be displayed instead of the static 0".


Followed their instructions & still not worked. ,I am still confused and baffled after these instructions........................
