Foreword except the items described in this service manual.
Read this manual carefully, especially precaution on microwave energy, and follow the procedure strictly.
Careless servicing and testing may expose yourself to the microwave energy leakage.

PRECAUTIONS
PRECAUTIONS TO BE OBSERVED BEFORE AND DURING SERVICING TO AVOID POSSIBLE EXPOSURE TO
EXCESSIVE MICROWAVE ENERGY
(a)
(b)
(c)
(d)
Do not operate or allow the oven to be operated with the door open.
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.
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.
Any defective or misadjusted components in the interlock, monitor, door seal, and microwave generation and transmis-
sion systems shall be repaired, replaced, or adjusted by procedures described in this manual before the oven is
released to the owner.

(2)liters water isequivalent to850Win measurement with IEC,
when measured with the following Power Output.
(A) 1. Fill twotest bowls with eachl Iiter water respectively
2. Use accurate thermometer and measure each water

measure the water
Get temperature rise by calculating the difference (water
temperature after cooking minus initial temperature) in
each bowl.
Then calculate average value(t) of both temperatures rises
in degrees centigrade.
Then work out;
Power Output (watt) =70 xAt
Where At is an Average Temperature Rise in degrees
centigrade.
Power Output shall be in the following range:

Temperature Rise Power Output
H%-t=-i
I,1
Power Output will be influenced by line voltage of power
supply. Consequently, correct power output must be
measured within 240V AC *2volts while unit is operating.
