PRECAUTIONS TO BE OBSERVED BEFORE AND DURING
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, or adjusted 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 should be performed
on each oven prior to release to the owner.

See the Service Manual of EM-S8000BS (SM-860278)
except the items described in this Service Manual.

In the area emitting the highest reading, switch the meter
to SLOW RESPONSE, and take a reading for minimum of
three (3) seconds. We recommended the pattern outline
shown below when the door surface is surveyed.
NOTE : Periodically check to be sure that the probe tip is
not worn or dirty.
The following U.S. standard applies to microwave ovens :
21 CFR 1030.10, Performance Standard for Microwave
Ovens.
It requires that the power density of the microwave
radiation emitted by a microwave oven shall not exceed
five (5) milliwatts per square centimeter at any point 5
centimeter (about 2 inches) or more from the external
surface of the oven.
All microwave ovens exceeding the emission level of
4mW/cm2must be reported to Dept. of Service for
microwave ovens and the manufacturer immediately and
the owner should be told not to use the microwave oven
until it has been repaired completely.
If a microwave oven is found to operate with the door open,
report to Dept. of Service, the manufacturer and CDRH*
immediately. Also tell the owner not to use the oven.
*CDRH : Center for Device and Radiological Health.
The interlock monitor switch acts as the final safety switch
protecting the customer from microwave radiation. If the
interlock monitor switch operates properly and the door
interlocks switch fails, the fuse will blow. If this happens,
all interlock switches must be replaced. The contacts of
the interlock switches may be welded together.

Measurement must be made with the microwave oven

NOTE : The water container must be a 600 milliliter beaker
and made of an electrically none conductive
material such as glass or plastic.
The cook tray must be in place when measuring
emission.
A properly operating door and seal assembly will normally
register emission on greater than 4mW/cm2 to allow for
measurement uncertainty with the cooking shelf or tray in
place.

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 1 liter water respectively.
2 . Use accurate thermometer and measure each
water temperature respectively.
(B) Place the two bowls on glass turntable.

(C) 1. Set cooking time to two (2) minutes. (“2 00”
appears in display)
2. Touch “START” key and operate oven for exactly
two (2) minutes.
(D) 1 . Take out the two bowls at once.
2. Stir both water with thermometer and measure the
water temperature rise respectively.
(E) 1 . Get temperature rise by calculation the difference
(water temperature after cooking minus initial
temperature) in each bowl.
2 . Then calculate average value(t) of both temperature
rises in degrees centigrade.
3. Then work out :
Power Output (watt) = 70 x ∆t
Where ∆t is an Average Temperature Rise in degrees
centigrade.
(F) Power Output shall be in the following range :
(G) Power Output will be influenced by line voltage of
power supply. Consequently, correct Power Output
must be measured within 120V AC ± 1 volt while

PRECAUTIONS TO BE OBSERVED BEFORE AND DURING
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, or adjusted 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 should be performed
on each oven prior to release to the owner.

to SLOW RESPONSE, and take a reading for minimum of
three (3) seconds. We recommended the pattern outline
shown below when the door surface is surveyed.

NOTE : Periodically check to be sure that the probe tip is
not worn or dirty.
The following U.S. standard applies to microwave ovens :
21 CFR 1030.10, Performance Standard for Microwave
Ovens.
It requires that the power density of the microwave
radiation emitted by a microwave oven shall not exceed
five (5) milliwatts per square centimeter at any point 5
centimeter (about 2 inches) or more from the external
surface of the oven.
All microwave ovens exceeding the emission level of
4mW/cm2must be reported to Dept. of Service for
microwave ovens and the manufacturer immediately and
the owner should be told not to use the microwave oven
until it has been repaired completely.
If a microwave oven is found to operate with the door open,
report to Dept. of Service, the manufacturer and CDRH*
immediately. Also tell the owner not to use the oven.
*CDRH : Center for Device and Radiological Health.
The interlock monitor switch acts as the final safety switch
protecting the customer from microwave radiation. If the
interlock monitor switch operates properly and the door
interlocks switch fails, the fuse will blow. If this happens,
all interlock switches must be replaced. The contacts of
the interlock switches may be welded together.

in measurement with IEC, when measured with the following
power output.
(1) Fill two beakers ( glass or plastic ) with each one liter
of tap water ( about 20oC ) and measure the water tem-
perature. ( Use a thermometer with a 1/10 degree gauge ).
(2) Place the beakers side by side in the center of the glass
tray.
(3) Close the door, set the “TIME”for two minutes. ( “200”
in the display window. ) Touch the “START”key and
heat the water exactly for two minutes.
(4) Take the beakers out, immediately stir the water and
measure the water temperature respectively.
(5) Calculate the temperature rise of water in each beaker.
Then calculate the average value of two temperature rises.
Output power can be calculated by the equation :
Power Output (W) = 70 x ∆t
Where ∆t is an average temperature rise in degrees
Centigrade.
(6) Power output shall be in the following range :
Average Temperature Rise Power Output
Minimum 23.0oF(12.8oC) 896W
Maximum 28.3oF(15.7oC) 1099W
(7) Power Output is affected by the line voltage under load.
For correct Power Output measurement, the line voltage
under load must be 120±1volts.
