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,
