CAUTION
•High voltages are present during the cook cycle. Extreme caution should be observed at all times.
•Abrasive cleansers,
•Before touching any oven component or wir- ing, always unplug the oven from its power source and discharge the capacitor by using a 20,000 ohm discharge resistor or use an insu- lated plastic handle screwdriver to short across the capacitor terminals.
•Check that the unit is grounded before trouble- shooting. Be careful of the high voltage circuits. Discharge any static charge from your body by touching ground before handling any part of the circuitry on the control board. Electrostatic dis- charge may damage the control circuit.
•Do not touch oven components or wiring dur- ing operation. Attach meter leads with alligator clips when making operational tests.
•For continued protection against radiation emis- sion, replace only with these types of switches:
Primary (Interlock) Switch:
•It is neither necessary nor advisable to attempt measurement of high voltage.
•Attaching the adaptor ground terminal to the wall receptacle cover screw does not ground the appliance unless the cover screw is metal and not insulated and the wall receptacle is grounded through the house wiring.
WARNING
•Disconnect the oven from electrical supply be- fore servicing. Failure to do so could result in electrical shock or death.
•Improper use of the grounding plug can result in a risk of electrical shock. Do not, under any circumstance, cut or remove the third ground prong from the power cord plug.

Damage Hazard
•Do not block the rear air intake openings or exhaust vents. Allow a few inches of space at the back of the oven where intake openings and exhaust vents are located. Blocking the air intake openings and exhaust vents can cause damage to the oven and poor cooking results. Make sure the microwave oven legs are in place to ensure proper airflow.
•Do not install the oven next to or over a heat source (a cooktop or range).
•Do not install oven in any area where exces- sive heat and steam are generated. This could cause fire, electrical shock, excessive exposure to microwave energy, other personal injury or damage to the outside of the cabinet.
