Foreword
Read this manual carefully, especally precaution on microwave enery, an follow the procedure strictly, careless servicing and testing may expose yourself to the microwave energy leakage.
PRECAUTIONS PRECAUTIONS TO BE OBSER VED BEFORE AND DURING SER VICING TO AVOID POSSIBLE EXPOSURE T O EXCESSIVE MICRO W AVE 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.

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 MICR OW AVE CONNECTIONS, WAVEGUIDE, FLANGES AND GAS­KETS MUST BE SECURE. NEVER OPERATE THE DEVICE WITHOUT A MICROWAVE ENERGY ABSOR­BING LOAD ATTACHED. NEVER LOOK AN OPEN WAVEGUIDE OR ANTENNA WHILE THE DEVICE IS ENERGIZED.
(All service adjustments must be made for mini-
mum microwave energy readings.)
NOTE: If the interlock monitor circuit operates and at the same time the fuse blows with the door open, be sure to replace the relay circuit board , interlock switch and monitor switch.

1.ADJUSTMENT PROCEDURE
TO AVOIDE POSSIBLE EXPOSURE TO MICROWAVE ENERGY LEAKAGE, THE FOLLOWING ADJUSTMENTS OF THE INTERLOCK SWITCHES SHOULD BE MADE ONLY BY AUTHORIZED SERVICE PARSONNEL.
PRIMARY INTERLOCK SWITCH, INTERLOCK MONITOR SWITCH AND DOOR SENSING SWITCH ADJUSTMENT (Figure 1)
(1) Loosen 2 screws securing the lever stopper. (2) Adjust the lever stopper position so that it is pushed up and pull backward until there is zero gap between the latch lever and the switch body on the primary interlock switch. At the same time there is about zero gap between latch lever and the switch body on the door sensing switch when the door latch is securely locked. (3) Tighten the lever stopper screws securely. (4) Make sure the interlock monitor switch closes after the primary switch opens when the door is opened very slowly, according to “CHECKOUT PROCEDURE FOR SWITCHES” on page 6. (5) Make sure the interlock monitor switch opens before the primary interlock switch closes when the door is closed very slowly, accoding to “CHECKOUT PROCEDURE FOR SWITCHES” on page 6. (6) Make sure the microwave energy leakage is below the limit of the reguration (5 mW/cm2 ) when measured with a detector.

4. PRECAUTIONS AND REPAIR SERVICE TIPS PRELIMINARY
A.SINCE NERARLY 4,000 VOLTS EXISTS IN SOME CIRCUITS OF THIS MICROWAVE OVEN, REPAIRS SHOULD BE CARRIED OUT WITH GREAT CARE.
B.TO AVOID POSSIBLE EXPOSURE TO MICROWAVE ENERGY LEAKAGE, THE FOLLOWING PRECAU­ TIONS MUST BE TAKEN BEFORE SERVICING.
(1) Before the power is applied. (a) Open and close door several times to make sure the interlock switch, door sensing switch and inter­ lock monitor switch operate properly. (Listen for the clicking sound from switches.) Make sure the interlock monitor switch is closed after the interlock switch and door sensing switch are open when the door is opened. (See pages 1 and 6) (b) Make sure the perforated screen and the choke dielectric of the door are correctly mounted. (2) After the power is applied. (a) Open and close the door to see if the interlock mechanism operates properly. (b) Check microwave energy leakage with a leakage detector and confirm the energy leakage is below 5 mW/cm2. (3) Do not operate the unit until it is copmletely repaired of any of the following coditions. (a) Door is not closed firmaly against the cavity front. (b) The hige is broken. (c) The choke dielectric or the door seal is damaged. (d) The door is bent or warped, or there is any other visible damage to the oven that may cause micro­ wave energy leakage.
Note:Always keep the seal clean.
(e) Make sure that there are no defective part in the interlock mechanism. (f) Make sure that there are no defective parts in the microwave generating and transmission assembly.(Especially wave guide.) (4) The following items should be checked after the unit is repaired. (a) The interlock monitor switch is connected correctly and firmly. (b) The magnet gasket on the magnetron is properly positioned. (c) Wave guide and oven cavity are intact.(No leakage of microwave energy). (d) The door can be properly closed and the safety swtches work ploperly. (e) The oven must be stopped when the door is opened or the time is up. The oven must not be operated with any of the above coponents removed or bypassed.

Maintenance:
The microwave are designed, manufactured, and tested for years of depentable operetion. However, the oven may require service from time to time if the consumable components listed below are not replaced at the apporopriate time. for protection from unexpected service calls and undue inconvenience, we recommend that the user has the listed parts replaced at the inter vals below, (at custmer cost). this will avoid the trouble of repeated service calls after the expiration of the warranty period.
Consumable components: When more than 1,250 hours of accumulative cooking time or more than 200,000 cycles of door opening/ closing is observed by key operations (See page 13 for more information), the following consumable components should be replaced. (Maintenance light in window display indicates when accumulative cooking time reaches 1,250 hours.)
