PRECAUTIONS TO BE OBSERVED BEFORE AND DURING

SERVICING TO AVOID POSSIBLE EXPOSURE TO

EXCESSIVE MICROWAVE ENERGY

(a)

Do not operate or allow the oven to be operated with the door open.

(b)

Make the following safety checks on all ovens to be serviced before activating the magnetron or other
microwave source, and make repairs as 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, (5) evidence of dropping or abuse.

(c)

Before 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.

(d)

Any defective or misadjusted components in the interlock, monitor, door seal, and microwave generation and
transmission systems shall be repaired, replaced, or adjusted by procedures described in this manual before
the oven is released to the owner.

(e)

A microwave leakage check to verify compliance with the Federal performance standard should be performed
on each oven prior to release to the owner.
