See the Setvice Manual of EM-X670S (SM-8601 77)
Foreword except the items described in this Service Manual.
Read thie manual carefully, especially precaution on microwave energy, and follow the procedure strictly.
LCareless 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 necessaty:
(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 compatiments,
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. POWER OUTPUT MEASUREMENT
NOTE
The Power Output specification 1000W on this model is
measured with IEC measurement. The Power Output is
measured with two (2) liters water is equivalent to 1000W in
measurement with IEC, when measured with the following
power output.
(A) 1. Fill two test bowls with each 1liter water respectively.
2. Use accurate thermometer and measure each
water temperature respectively.
(B) Place the two bowls on glass turntable.

Set cooking time to two (2) minutes. (“2 00 appears
in display)
Touch START key and operate oven for exactly two
(2) minutes.
Take out the two bowls at once.
Stir both water with thermometer and measure the
water temperature rise respectively.
Get temperature rise by calculation the difference
(water temperature after cooking minus initial
temperature) in each bowl. w
Then calculate average value(t) of both temperature
rise in degrees centigrade.
Then work out;
Power Output (watt) =70 xAt
Where At is an Average Temperature Rise in degrees
centigrade. d
Power Output shall be in the following range:
Average Microwave
Temperature Rise Power Output
Minimum
11.2°C 777 w
Maximum
13.PC 966 W
Power Output will be influenced by line voltage of
power supply. Consequently, correct power output
must be measured within 240V AC ~2volt while unit
is operating.
