Residual heat indicator
1 Warning! Risk of burns from residual heat. After being switched off, the cooking zones need some time to cool down. Look at the residual heat indi- cator 
.
3 Residual heat can be used for melting and keeping food warm.
The induction cooking zones create the heat required for cooking directly in the base of the cookware. The glass ceramic is merely heated by the re- sidual heat of the cookware.
The cooling fan switches itself on and off depending upon the temperature of the electronics.
