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.
 If the
-
or
+
button is pressed for an extended
period of time, the display scrolls quickly though the
power levels and timer minutes.
Switching on the hob
To switch the hob on, press and hold the button
for approximately one second.
Switching on the cooking zones
Each cooking zone is controlled using a selector
button and a power adjustment device
consisting of a double
-
and
+
button.
• To begin operating a cooking zone, press the
corresponding control button and set the desired
power level (between 0 and 9) using the buttons
-
and
+
.
Booster function*
The booster function for some of the cooking zones
may be used to shorten heating-up times. It may be
activated 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
and:
• Press the
-
button: the power of the cooking zone
will progressively decrease until it is switched off.
Programming the cooking duration
 All the cooking zones may be programmed
simultaneously, for a duration between 1 and 99
minutes.
1. Select the cooking zone using the corresponding
selector button.
2. Adjust the temperature.
3. Press the
programming button.
