PROPER USE AND SERVICE PRECAUTIONS 

CAUTION  : This Device is to be Serviced Only by Properly Qualified Service Personnel. Consult the Service

Manual for Proper Service Procedures to Assure Continued Safety Operation and for Precautions
to be Taken to Avoid Possible Exposure to Excessive Microwave Energy.

1. For Safe Operation 

Damage that allows the microwave energy (that cooks or heats the food) to escape will result in poor cooking and
may cause serious bodily injury to the operator.
IF ANY OF THE FOLLOWING CONDITIONS EXIST, OPERATOR MUST NOT USE THE APPLIANCE.
(Only a trained service personnel should make repairs.)

1)  A broken door hinge.
2)  A broken door viewing screen.
3)  A broken front panel, oven cavity.
4)  A loosened door lock.
5)  A broken door lock.

The door seal area and oven cavity surface be kept clean.
No grease, soil or spatter should be allowed to build up on these surfaces or inside the oven.
DO NOT ATTEMPT TO OPERATE THIS APPLIANCE WITH THE DOOR OPEN. The microwave oven has
concealed switches to make sure the power is turned off when the door is opened. Do not attempt to defeat them.
DO NOT ATTEMPT TO SERVICE THIS APPLIANCE UNTIL YOU HAVE READ THIS SERVICE MANUAL.

2. For Safe Service Procedures.

1) If the oven to be serviced is operative, a microwave emission check should be performed prior to servicing the

oven.

2) If any ascertained oven unit is found to have excessive emission level 5mW/cm

2

, the service person should :

(a) inform the manufacturer, importer or assembler,
(b) repair the unit at no cost to the owner,
(c) attempt to ascertain the cause of the excessive leakage,
(d) tell the owner of the unit not to use it until the oven has been brought into compliance.

3) If the oven operates with the door opened, the service person should tell the user not to operate the oven and

contact the manufacturer immediately.

CAUTION

MICROWAVE RADIATION

PERSONNEL SHOULD NOT BE EXPOSED TO THE MICROWAVE ENERGY WHICH MAY RADIATE
FROM THE MAGNETRON OR OTHER MICROWAVE GENERATING DEVICE IF IT IS IMPROPERLY
USED OR CONNECTED. ALL INPUT AND OUTPUT MICROWAVE CONNECTIONS, WAVEGUIDES,
FLANGES, AND GASKETS MUST BE SECURED. NEVER OPERATE THE DEVICE WITHOUT A
MICROWAVE ENERGY ABSORBING LOAD ATTACHED IN IT. NEVER LOOK INTO AN OPEN
WAVEGUIDE OR ANTENNA WHILE THE DEVICE IS ENERGIZED.
