So far we have only used the 30" Induction Cooktop one time to season our new stainless steel pots & pans (so food won't stick). The QUICK START GUIDE was helpful to understand how to use the induction cooktop, however, I was unable to turn one of the burners back on to use it again for another pot due to the "H" indicator being displayed.
