Start-up and use
! The glue applied on the gaskets leaves traces of
grease on the glass. Before using the appliance, we
recommend you remove these with a special non-
abrasive cleaning product. During the first few hours
of use there may be a smell of rubber which will
disappear very quickly.
! A few seconds after the hob is connected to the electricity
supply, a buzzer will sound. The hob may now be switched
on.
Types of noise during normal hob operation:
• Buzz: due to the vibration of the metallic parts that
make up the induction element and the pot; it is
generated by the electromagnetic field required for
heating and increases as the power of the induction
element increases.
• Soft whistle: heard when the pot placed on the
heating zone is empty; the noise disappears once
food or water is placed into the pot.
• Crackle: produced by the vibration of materials on
the bottom of the pot due to the flow of parasitic
currents caused by electromagnetic fields
(induction); can be more or less intense depending
on the material making up the bottom of the pot, and
decreases as the pot dimensions increase.
• Loud whistle: heard when two induction elements of
the same group function simultaneously at maximum
power and/or when the booster function is set on
the larger element while the other is auto-adjusted.
Noise is reduced by decreasing the power level of
the auto-adjusted induction element; pot bottom
layers made of different kinds of materials are
among the main causes of this noise.
• Fan noise: a fan is necessary to ensure the hob
functions correctly and to safeguard the electronic
unit from possible overheating. The fan functions at
maximum power when the large induction element is at
maximum power or when the booster function is on; in
all other cases, it works at average power depending
on the temperature detected. Furthermore, the fan may
continue to work even after switching the hob off, if the
temperature detected is high.
The types of noise listed above are due to induction
technology and are not necessarily operational faults.

Booster function*
The booster function for some of the cooking zones may
be used to shorten heating-up times. It may be activated
Booster
by pressing the button. The indicator light directly
above the button will illuminate. This function boosts
the power to 2000 W or 3000 W, depending on the size
of the relevant cooking zone.
The booster stops automatically after 4 minutes. While
the booster for one of the cooking zones is active, the
corresponding front or rear cooking zone will operate
at a reduced power level (e.g. if the booster for the
rear left-hand hotplate has been activated, the power
level of the front left-hand hotplate will be reduced).
For further information, please refer to the Technical
description of the models.
Switching off the cooking zones
To switch off a cooking zone, select it using the
corresponding selector button
