To switch on and increase the heat setting, turn the knob counterclockwise. To decrease the heat setting, turn the knob clockwise. Turn the knob to 0 to switch off the appliance. The Power indicator is activated when either of the zones are turned on, and will stay on until the cooking zones are switched off.
Before first use: Put cookware containing water on each cooking zone, set the maximum position, and operate the appliance for 10 minutes to burn off residue. Then, operate at minimum position for 20 minutes. Odour and smoke may occur; ensure adequate ventilation. A humming sound when a zone is operating is normal for ceramic glass hobs and does not indicate a fault.
