Quotations from the manual of a new electric oven microwave. The microwave is an LG MP-9485S light oven "SolarDOM".
I'm quoting here only from the English parts, not from the bad Hungarian translation even though that can give a few laughs as well.
A very safe appliance
Your oven, SolarDOM, is one of the safest of all home appliances. When the door is opened, the oven automatically stops producing microwaves. Microwave energy is converted completely to heat when it enters food, leaving no “left over” energy to harm you when you eat your food.
THIS OVEN SHOULD NOT BE USED FOR COMMERCIAL CATERING PURPOSES.
Microwaves are a form of energy similar to radio and television waves and ordinary daylight. Normally, microwaves spread outwards as they travel through the atmosphere and disappear without effect. This ovens, however, have a magnetron which is designed to make use of the energy in microwaves. Electricity, supplied to the magnetron tube, is used to create microwave energy.
If your oven does not operate properly, unplug it from the electrical socket and then plug it back in.
If the clock (or display) shows any strange looking symbols, unplug your oven from the electrical socket and plug it back and reset the clock.
Warning
Please ensure cooking times are correctly set as over cooking may result in the FOOD catching fire and subsequent damage to your oven.

Please ensure cooking times are correctly set as over cooking may result in FIRE and subsequent DAMAGE to the OVEN.
Do not cook food wrapped in paper towel, unless your cook book contains instructions for the food you are cooking.
Below are scans of the safety warnings section of the manual. Note especially how many repetitions they contain.
