• Loud whistle: heard when two induction elements of
GB
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.
Initial Light Conditions
When power is initially applied to the Cooktop, the to-
uch control conducts a calibration process for the to-
uch keys, which requires a low level of ambient light in
the area of the touch keys.
If during this calibration process excessive ambient
lighting is detected the User Interface displays „FL"
(Infrared Ambient Light Error) and the control cali-
bration process is suspended. In order to rectify the
process any lighting that could effect the calibration
process should be switched off (e.g. halogen cooker
hood lighting). The error will disappear when satisfac-
tory ambient lighting is detected and the touch control
calibration procedure will now complete satisfactorily.
-The „FL" error can only be generated within approx 3s
of initial power being applied to the cooktop.
-We recommend that the user switches off all cooker
hood lighting and lighting directed towards the cook-
top when power is initially applied to the cooktop.
-After the touch control has conducted its initial cali-
bration process, (approx 3s) any cooker hood or other
lighting can be switched on as normal and will not af-
fect the operation of the touch control.
Switching on the hob
When power is initially applied to the Cooktop, the
touch control conducts a calibration process for the
touch keys, which requires a low level of ambient
light in the area of the touch keys. If excessive am-
bient lighting is detected, the User Interface displo-

ays „FL" error and the calibration is suspended. The
error will disappear when satisfactory ambient ligh-
ting is detected and the touch control calibration pro-
cedure will now complete satisfactorily
After connecting the hob to the electricity mains, the
touch pannel might be automatically locked. To un-
clock the pannel press and hold the Control Panel
Loock button
To switch the hob on, press and hold the
approximately one second.
The cooktop is switched On when a beep sound is
emmited and all the cooking zones displays show
the digit point.
When the cooktop is OFF, after 5 sec, the control As
soon as we Touch a key, the KEYLOCK LED
goes ON and we can continue to operate us normal
unlocking the keyboard switches off to reduce the power
consumption.
Switching off the cooktop is signalled by 3 beep sound
Power Management for ECO Cooktop
For ECO power cook tops, each time the user tries to
increase the power, the total power level of the Cooktop
is calculated. If this total power level is greater than the
Cooktop power limit, the power increase is not allowed.
An error beep sounds and the heater display shows an
'r' for 3 seconds .
