5 Touch Control Autarkic Cooking Hobs Information
The Touch Control works on the basis of the infrared principle, i.e. a signal is transmitted with a
transmitter which is then reflected by the finger and received once more.
5.1 Instructions on the operation / possible operation errors if the buttons do
not function:
Do not use with the flat finger. Hold the finger relatively upright.
Otherwise 2 buttons can be activated, this is not signalled.
Please do not approach slowly, especially not from the side, it is better to approach the button
faster.
A signal change is above all evaluated.
Applying excessive pressure to the cooking hob will not make a difference.
It is better to release it for 5 sec. and then press the button again.
If the adjustment of the cooking stage/timer does not continue after the button has been released,
this is due to the fact that the Touch Control receives a "Button Pressed" signal even from a
distance of some mm.
If the user interface is not adjacent to the glass ceramic, the signal for the key evaluation is very
much smaller and the keys can not be operated any more, i.e. pay always attention to intact
plastic carriers.
If the appliance switches off without that the glass ceramic has been touched, is this because a
key in the extreme case.is switching even in a distance / height of 10 mm. This is the function
principle of the touch control and is a normal behaviour. I.e. do not replace the touch control!
