See the Service Manual of EM-X670S (SM-860177)

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 Ieskage.

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 necessa~:

(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. POWER OUTPUT MEASUREMENT

NOTE

The Power Output specification 750Won this model is

measured with IEC measurement. The Power Output is

measured with two (2) liters water is equivalent to 750W in

measurement with IEC, when measured with the following

power output.

(A) 1. Fill two test bowls with each 1 liter water respectively.

(c)

(D)

(E)

(F)

(G)

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.

Then calculate average value(t) of both temperature

rise in degrees centigrade.

Then work out;

Power Output (watt) = 70 x At

Where At is an Average Temperature Rise in degrees

centigrade.

Power Output shall be in the following range:

Average

Microwave

Temperature Rise

Power Output

Minimum

9.&c

672 W

Maximum

12.WC

861 w

Power Output will be influenced by line voltage of

power supply. Consequently, correct power output

must be measured within 240V AC f 2 volt while unit

is operating.

2. Use accurate thermometer and measure each

water temperature respectively.

(B) Place the two bowls on glass turntable.
