2)GRILL COOKING

This is a method of cooking with radiant heat from the grill heater on the top of the oven. This is a traditional way of cooking which quickly seals and browns food evenly. The temperature inside the oven is fixed at 180°C, which is ideal grilling temperature for this oven.

3)CONVECTION COOKING

This is a method of cooking with hot air from the convection heater situated at the rear of the oven. This method allows food to be browned evenly without losing any of the juices. Air heated by the heater is circulated in the oven by a fan. This enables the efficient heating and cooking of food. The temperature inside the oven can be controlled according to the type and weight of food being cooked.

4)COMBINATION COOKING

Using a combination of microwaves, hot air and radiant heat, this solid state control can cook alternately, according to the cycles programmed. This efficient method of cooking fully utilizes the advantages of all three functions, giving quick results with a traditional appearance to your cooking.
