service manual.

Foreword

Read this manual carefully, especially precaution on microwave energy, and follow the procedure strictly. Careless ser- -

vicing and testing may expose yourself to the microwave energy leakage.

PRECAUTIONS

PRECAUTIONS TO BE OBSERVED BEFORE AND DURING SERVICING TO AVOID POSSIBLE EXPOSURE TO EXCES-

SIVE MICROWAVE ENERGY

(a)

(b)

(c)

(d)

Do not operate or allow the oven to be operated with door open.

Make the following safety checks on all ovens to be serviced before activating the magnetron or other micro-

wave source, and make repairs as necessary:

(1) Interlock operation, (2) proper door closing, (3) seal and sealing surfaces (arcing, wear, and other dam-

age), (4) damage to or loosening of hinges and latches, (5) evidence of dropping or abuse.

Before turning on microwave power for any service test or inspection within the microwave generating com-

partments, check the magnetron, wave guide or transmission line, and cavity for proper alignment, integrity,

and connections.

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.

(1) Prepare 1000*5g tap water.

(2) Adjust water temperature to 10”*2”C.

(3) Pour water into a container made of borosilicate

glass, 180mm outer diameter cylinder, maximum

3mm thickness.

Note: Use the container kept on the room tempera-

ture.

(4) Place the container in the center of oven cavity.

(5) Set the heating time for 49 seconds and rating

full

power and then start oven.

(6) Take the container out immediately when heating

time is up.

(7) Stir water for making even water temperature in the
