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.

BEFORE SERVICING

Before  servicing  an  operative  unit,  perform  a  microwave  emission  check  as  per  the  Microwave 
Measurement Procedure outlined in this service manual.
If microwave emissions level is in excess of the specified limit, contact SHARP ELECTRONICS 
CORPORATION immediately  @1-800-237-4277.

If the unit operates with the door open, service person should 1) tell the user not to operate the 
oven and 2) contact SHARP ELECTRONICS CORPORATION and Food and Drug Administration's 
Center for Devices and Radiological Health immediately.

Service  personnel  should  inform  SHARP  ELECTRONICS  CORPORATION  of  any  certified  unit 
found with emissions in excess of 4mW/cm

2

. The owner of the unit should be instructed not to use 

the unit until the oven has been brought into compliance.
