Control panel lock
When the hob is switched on, it is possible to lock the
oven controls in order to avoid accidental changes
being made to the settings (by children, during
cleaning, etc.). Press the
panel:
the "L" will appear on the cooking zone displays.
To use any of the controls (e.g. to stop cooking), you
must switch off this function. Press the
few moments, the indicator light will switch off and the
lock function will be removed.
Switching off the hob
Press the button to switch the appliance off.
If the control panel lock has been activated, the
controls will continue to be locked even after the hob is
switched on again. In order to switch the hob on again,
you must first remove the lock function.
Practical advice on using the appliance
To obtain the best results from your hob:
• Use pans with a thick, flat base in order to fully
utilise the cooking zone.
• Always use pans with a diameter which is large
enough to cover the hotplate fully, in order to use all
the available heat.
• Make sure that the base of the cookware is always
clean and dry, in order to fully utilise and extend the
life of both the cooking zones and the cookware.
• Avoid using the same cookware which has been
used on gas burners: the heat concentration on gas
burners may distort the base of the pan, causing it
not to adhere correctly.
Safety devices
Residual heat indicators
Each cooking zone is equipped with a residual heat
indicator. This indicator signals which cooking zones
are still at a high temperature. If the power display
shows , the cooking zone is still hot. It is possible,
button to lock the control
button for a
for example, to keep a dish warm or melt butter or
chocolate. As the cooking zone cools, the power
display will show . The display switches off when the
cooking zone has cooled sufficiently.
DO NOT TOUCH THE COOKING ZONE
EVEN IF THE DISPLAY SHOWS
Overheating protection
If the electronic elements overheat, the hob switches
F
off automatically and appears on the display,
followed by a flashing number. When the temperature
has reached a suitable level, this message disappears
and the hob may be used again.
Safety switch
The appliance has a safety switch which automatically
switches the cooking zones off after they have been
in operation for a certain amount of time at a particular
power level. When the safety switch has been
triggered, the display shows "0".
For example: the right rear hotplate is set to 5 and will
switch off after 5 hours of continuous operation, while
the front left hotplate is set to 2 and will switch off after
8 hours.

Buzzer
This can also indicate several irregularities:
• An object (a pan, cutlery, etc.) has been placed on
the control panel for more than 10 seconds.
• Something has been spilt on the control panel.
• A button has been pressed for too long. All of the
above situations may cause the buzzer to sound.
Remove the cause of the malfunction to stop the
buzzer. If the cause of the problem is not removed,
the buzzer will keep sounding and the hob will
switch off.
