CAUTIONS

Unlike other appliances, the microwave oven is high-voltage and high-current equipment. Though it is free from danger in ordinary use, extreme care should be taken during repair.

•DO NOT operate on a 2-wire extension cord during repair and use.

•NEVER TOUCH any oven components or wiring during operation.

•BEFORE TOUCHING any parts of the oven, always remove the power plug from the outlet.

•For about 30 seconds after the oven stops, an electric charge remains in the high voltage capacitor. When replacing or checking, you must discharge the high voltage capacitor by shorting across the two terminals with an insulated screwdriver.

•Remove your watches whenever working close to or replacing the Magnetron.

•DO NOT touch any parts of the control panel circuit. A resulting static electric discharge may damage this P.C.B.

•NEVER operate the oven with no load.

•NEVER injure the door seal and front plate of the oven cavity.

•NEVER put iron tools on the magnetron.

•NEVER put anything into the latch hole and the interlock switches area.

MICROWAVE RADIATION

Personnel should not be exposed to the microwave energy which may radiate from the magnetron or other microwave generating device if it is improperly used or connection. All input and output microwave connections, waveguide, flange, and gasket must be secure never operate the device without a microwave energy absorbing load attached.

Never look into an open waveguide or antenna while the device is energized.

•Proper operation of the microwave oven requires that the magnetron be assembled to the waveguide and cavity. Never operate the magnetron unless it is properly installed.

•Be sure that the magnetron gasket is properly installed around the dome of the tube whenever installing the magnetron.
