2. DO NOT LET WIRE LEADS TOUCH TO THE FOLLOWING PARTS:
1) High voltage parts:
Magnetron, High Voltage Transformer, High Voltage Capacitor And High Voltage Rectifier Assembly.
2) Hot parts:
Oven Lamp, Magnetron, High Voltage Transformer And Oven Cavity.
3) Sharp edge:
Bottom Plate, Oven Cavity, Waveguide Flange, Chassis Support And Other Metallic Plates.
4) Movable parts (to prevent a fault)
