The Sharp R25JTF commercial microwave oven is made of stainless steel with a lighted digital display, manual time input, and 11 variable power levels. This 0.7-cubic-foot unit can hold a half-size steam table pan, with time automatically adjusting for a double portion. For thorough cooking, this microwave defrosts, cooks, and finishes with different power levels, and its defrost cycle runs in three time stages with three power levels. Because this heavy-duty unit remembers how often buttons are used and adjusted, it enables users to efficiently track operation. When cooking is done, one of two audible tones will alert operators, though it can also be switched off for silent mode.
