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.

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 should be performed on each oven prior to release to the owner.

DO NOT BECOME EXPOSED TO RADIATION FROM THE MICROWAVE

GENERATOR OR OTHER PARTS CONDUCTING MICROWAVE ENERGY.

This microwave oven is designed for household use only.

It is not recommended for commercial purpose.

• DO NOT operate on a 2-wire extension cord during

repair and use.

• NEVER TOUCH any oven components or wiring during

operation .

• BEFORE TOUCHING any parts of the oven, always

remove the power plug from the outlet.

• For about 30 seconds after the oven stop, an electric

charge remains on the high voltage capacitor. When

replacing or checking, you must discharge the

capacitor by shorting across the two terminals with an

insulated screwdriver.

• Remove your watches whenever working close to or

replacing the Magnetron.

• NEVER operate the oven with no load.

• NEVER damage the door seal or front plate of the

oven cavity.

• NEVER put iron tools on the magnetron.

• NEVER put anything into the latch hole and the

interlock switches area.

• Proper operation of the microwave oven requires that

the magnetron be assembled to the waveguide and

cavity. Never operate the magnetron unless it is

properly installed.

• Be sure that the magnetron gasket is properly installed

around the dome of the tube whenever installing the

magnetron .

2-1

Unlike other appliances, the microwave oven is
high-voltage and high-current appliance.

Though it is free from danger in ordinary use,
extreme care should be taken during repair.

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,
waveguide,flange and gasket must be secure
never operate the device without a microwave
energy absorbing load attached.

Never look into an open waveguide or antenna
while the device is energized.
