For the hob to operate the cooker switch on the wall has to be switched to the on position. 

Traditional cooking zones (A) consist of singular circular heating elements. They turn red approximately 10 seconds after they have been switched on.

Each cooking zone is fitted with a control knob (D) which allows you to select from 12 different temperatures between 1 and a maximum of 12. 

The extendable radiant elements (B) are distinguished by the fact that they have a double heating zone. You can switch the smaller internal cooking zone on its own, or both the external and internal zones. 

The control knob (D) allows you to choose between two power levels, which may be adjusted between a minimum value of 1 and a maximum of 12. 

• The lowest power level can be set by turning the knob clockwise from 1 to 12.

• Turn the knob completely round (⊚), until you hear a slight click, to enable the maximum power level. This in turn can be adjusted between 12 and 1 by turning the knob anticlockwise. To restore the maximum power level, turn the knob and set it back to position 0. 

Operation indicator light (C) is illuminated when a heating zone is activated. 

Residual heat indicator light (E) indicates that one or more cooking zones are at a temperature greater than 60°C, even after the cooking zones have been switched off. 

To remove stubborn dirt on the cooktop, use a scraper for glass ceramics with soapy water. Rinse well and dry it thoroughly.
