ENGINEERING CONSIDERATIONS: (Not for Field Representative's Use)

The products covered by this Report are microwave cooking appliances

intended for household use. The appliances incorporate air cooled magnetrons,

with a transformer for the high voltage and filament voltage supplies, for

generating microwave energy. The ovens are provided with a minimum of two

door interlocks, designated as the primary and secondary interlocks, which

serve to prevent generation of microwave energy when the oven door is opened.

The product is provided with an interlock monitor circuit which

functions if there is failure of the monitored interlocks thereby terminating

operation of the appliance. It is then necessary to have the product serviced

by a qualified serviceman.

For the schematic diagram, refer to the Ill.1 for UL Models and the

Ill.2 for cUL Models. Refer to ILL. 2A for both UL&CUL Models.

For the schematic diagram of MM720C##-PM, MM720C##-PMB, refer to the

ILL. 9 for UL Models and the ILL. 9A for cUL Models.
