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, oradjusted 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 and CSA Standard should be performed on each oven prior to release to the owner.

Proper operation of the microwave ovens requires that the magnetron be assembled to the wave guide 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 wheneverinstalling the magnetron.
Routine service safety procedures should be exercised at all times.
Untrained personnel should not attempt service without a thorough review of the test
procedures and safety information contained in this manual.

FOREWORD

Read this Manual carefully. Failure to adhere to or observe the information in this Manual may result in exposing

SPECIFICATIONS

CAUTIONS

Unlike other appliances, the microwave oven is high-voltage and high-current equipment.
Though it is free from danger in ordinary use, extreme care should be taken during repair.

DO NOT operate on a 2-wire extension cord duringrepair and use.
NEVER TOUCH any oven components or wiring duringoperation.
BEFORE TOUCHING any parts of the oven, alwaysremove the power plug from the outlet.
For about 30 seconds after the oven stops, an electriccharge remains in the high voltage capacitor. Whenreplacing or checking, you must discharge the highvoltage capacitor by shorting across the two terminals with an insulated screwdriver.
Remove your watches whenever working close to orreplacing the Magnetron.
DO NOT touch any parts of the control panel circuit. Aresulting static electric discharge may damage thisP.C.B.
NEVER operate the oven with no load.
NEVER injure the door seal and front plate of the ovencavity.
NEVER put iron tools on the magnetron.
NEVER put anything into the latch hole and the interlock switches area.

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 connection.
Allinput 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.

Proper operation of the microwave oven requires thatthe magnetron be assembled to the waveguide andcavity. Never operate the magnetron unless it isproperly installed.
Be sure that the magnetron gasket is properlyinstalled around the dome of the tube whenever installing the magnetron.

THE OVEN IS TO BE SERVICED ONLYBY PROPERLY QUALIFIED SERVICE PERSONNEL.

GENERAL INFORMATION FOR SERVICE

GENERAL PRECAUTIONS IN USE

A. Never operate the unit when it is empty. nOperating the oven with no load may shorten the life of the magnetron. Whenever cooking dry foods (dried fish, bread, etc.) or a small amount of food, be sure to put a glass of water into the cooking
compartment. The glass turntable may become hot after operating, be careful when touching it.
Aluminum foil should be avoided because it will disrupt cooking and may cause arcing. However, small pieces may be used to cover some parts of food to slow the cooking. Any aluminum foil used should never be closer than 2.5 ¢m to any side wall of the oven.
