SAVE THESE INSTRUCTIONS GROUNDING INSTRUCTIONS DANGER Electric Shock Hazard Touching some of the internal components can cause serious personal injury or death. Do not disassemble this appliance. WARNING Electric Shock Hazard Improper use of the grounding can result in electric shock. Do not plug into an outlet until appliance is properly installed and grounded. Three-pronged

(grounding) plug This appliance must be grounded. In the event of an electrical short circuit, grounding reduces the risk of electric shock by providing an escape wire for the electric current. This appliance is equipped with a cord having grounding wire with a grounding plug. The plug must be plugged into an outlet that is properly installed and grounded. Consult a qualified electrician or serviceman if the grounding instructions are not completely understood or if doubt exists as to whether the appliance is properly grounded. If it is necessary to use an extension cord, use only a 3-wire extension cord that has a 3-pronged grounding plug, and a 3-slot receptacle that will accept the plug on the appliance. The marked rating of the extension cord shall be equal to or greater than the electrical rating of the appliance. 44 1. A short power-supply cord is provided to reduce the risks resulting from becoming entangled in or tripping over a longer cord. 2. Longer cord sets or extension cords are available and may be used if cared is exercised in their use. 3. If a long cord sets or extension cord is used:

1) The marked electrical rating of the cord set or extension marked electrical rating of the cord set or extension cord should be at least as great as the electrical rating of the appliance. 2) The extension cord must be a grounding-type 3-wire cord; and 3) The longer cord should be arranged so that it will not drape over the countertop or tabletop where it can be pulled on by children or tripped over unintentionally. Radio Interference 1. Operation of the microwave oven may cause interference to your radio, TV or similar equipment. 2.
