PRECAUTIONS
PRECAUTIONS TO BE O~SERVED BEFORE AND DURING SERVICING TO AVOID POSSIBLE EXPOSURE TO EX-
CESSIVE MICROWAVE ENERGY
L
(a)
(b)
(c)
L (d,
Do not operate or allow the oven to be operated with the door open.
Make the following safety checks on all ovens to be serviced before activating the magnetron or other microwave source,
and make repairs as necessary:

damage to or loosening of hinges and latches, (5) evidence of dropping or abuse.
8efore turning on microwave power for any service test or inspection within the microwave generating compartments,
check the magnetron, wave guide or transmission line, and cavity for proper alignment, integrity, and connections.
Any defective or misadjusted components in the interlock, monitor, door seal, and microwave generation and trans
mission systems shall be repaired, replaced, or adjusted by procedures described in this manual before the oven is released
