START-UP & USE
The glue applied to 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 metal parts that make up the induction element and the
saucepan/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 saucepan or pot placed on the heating zone is empty; the noise
disappears once food or water is placed into the pan.
• Crackle: Produced by the vibration of materials on the bottom of the saucepan or pot due to the
flow of parasitic currents caused by electromagnetic fields (induction); can be more or less
depending on the material making up the bottom of the saucepan or pot, and decrease as the
saucepan 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. Saucepan or pot bottom layers are among the main cause of this noise.
• Fan Noise: A fan is necessary to ensure the hob functions correctly and to safeguard the
electronic until 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 the induction technology and are not necessarily operational
faults.
If the or button is pressed for an extended period of time, the display scrolls through 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
lever (between 0 and 9) using the buttons
