Page 7: Introduction
Introduction The Advantium 120 V ATC is an "Above The Cooktop" oven that has the functionality of a microwave, convection, and speedcook oven. Four heat sources are available for cooking. A 500-watt halogen light and 700-watt ceramic heater are located at the top of the unit. A convection system, located behind the right- side of the oven cavity, provides a 1550-watt heat source and fan to circulate cavity air.
