EXPOSURE TO EXCESSIVE MICROWAVE ENERGY
(a) Do not operate or allow the oven to be operated with the door opened.
(b) Make the following safety checks on all ovens to be serviced before activating the magnetron or other
micro-wave source, and make repairs if necessary: (1) Interlock operation, (2) proper door closing, (3)
seal and sealing surfaces (arcing, wear, and other damage), (4) damage to or loosening of hinges and
latches, and (5) evidence of dropping or abuse.
(c) Before turning on microwave power for any service test or inspection within the microwave generating
com-partments, check the magnetron, wave guide or transmission line, and cavity for proper
alignment, integrity, and connections.
