Important Information Important Notices for Servicers and Consumers ACP will not be responsible for personal injury or property damage from improper service procedures. Pride and workmanship go into every product to provide our customers with quality products. It is possible, however, that during its lifetime a product may require service.
Important Safety Information ! WARNING Read the following information to avoid possible exposure to microwave radiation: The basic design of the Microwave Oven makes it an inherently safe device to both use and service. However, there are some precautions which should be followed when servicing the microwave to maintain this safety. These are as follows: 1. Always operate the unit from an adequately grounded outlet. Do not operate on a two-wire extension cord. 8.
IMPORTANT SAFETY INSTRUCTIONS Recognize this symbol as a SAFETY message !

Visible bubbling or boiling when the container is removed from the microwave oven is not always present. THIS COULD RESULT IN VERY HOT LIQUIDS SUDDENLY BOILING OVER WHEN A SPOON OR OTHER UTENSIL IS INSERTED INTO THE LIQUID.
