4.1.3 Cookware detector signal
Every cooking zone has a "cookware detector" that only starts the
cooking if there is a well positioned container with the suitable
characteristics present on the hotplate.
If the container is not well positioned or is not made of the correct
material and still tries to activate the hotplate, after a few seconds from
the hotplate's activation, the symbol will appear on the display.
4.1.4 Residual heat
Each cooking zone is equipped with a residual heat warning device. After
any zone is switched off, a flashing " " may appear on the display. This
warns that the cooking zone concerned is still very hot. Cooking can be
restarted while the " " is flashing: in this case, proceed as described in
point "3".

When not in use, the hob can be "locked" from being accidently turned on
by children.

completely to the left until 5 L appears on the display. Then release the
knobs.
To unlock it repeat the same operation: The hotplates' displays will show
a 0 that will indicate that the hotplates' lock has been deactivated.
