See the service manual

of EM-S829(SM-860043) except

the items described in this service manual.

Foreword

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) 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.

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 transmis-

sion systems shall be repaired, replaced, or adjusted by procedures described in this manual before the oven is

released to the owner.

NOTE

(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 calculating the difference (water

temperature after cooking minus initial temperature) in

each bowl.

Then calculate average value(t) of both temperature rises

in degrees centigrade.

Then workout;

Power Output (watt) = 70 x

Power output shall be in the following range

Average Microwave

temperature rise

Power output

Minimum

10.4”C

728W

Maximum

13.3°C

931W

Power Output will be influenced by line voltage of power

supply. Consequently, correct power output must be

measured within 240 VAC~2volts while unit is operating.

The power output specification, 910Won this model is measured

with IEC measurement. The power output is measured with two (2)

liters water isequivalent to910Win measurement with IEC, when

measured with the following power output.

(A) 1, Fill twotest bowls with eachl Iiter water respectively.

2. Use accurate temperature “C and measure each water

temperature respectively.

(B) Place thetwobowls on glass turntable.
