Protection against overheating
If the hob is used intensively, e.g. several burners at maximum level for a long time, a temperature sensor detects possible overheating and automatically adjusts all the lit burners to minimum.
If the hob temperature keeps rising although the flame level has been reduced, all the lit burners are automatically turned off and a safety device is set on all the four burners.
If you select all the burners with the Timer
Control 
(one at a time) Code number 9 flashes in the cooking time display.
Caution! When the safety device is set on all the burners, their controls cannot be operated for about 60 seconds.
After the 60 seconds, you can reactivate all the burners by touching the Increasing Control 
and the Decreasing Control 
of one of the four burners at the same time.
Once the safety device has been removed, wait until the hob has cooled down before using it again.
Child Safety Function
To avoid children operating the hob controls, it is possible to lock them.
1.Touch the “Lock” Control 
for about 3 seconds. The red indicator next to the “Lock”
symbol 
lights up and an acoustic signal
sounds.
Now all the hob controls are locked, except the main ON/OFF Touch Control.
Any lit burner keeps operating, but cannot be adjusted.
