1. Steady, flat location
This microwave oven should be set on a steady, flat surface. This microwave oven is designed for counter top use only. 2. Leave space behind and side All air vents should be kept a clearance. If all vents are covered during operation, the oven may overheat and, eventually, cause failure. 3. Away from radio and TV sets Poor television reception and radio interference may result if the oven is located close to a TV, radio, antenna or feeder and so on. Position the oven as far from them as possible. 4. Away from heating appliances and water taps Keep the oven away from hot air, steam or splash when choosing a place to position it, or the insulation might be adversely affected and breakdowns occur. 5. Power supply Check your local power source. This microwave oven requires a current of approximately 12(8)amperes, 230 Volts, 50 Hz. Power supply cord is about 1.2 meters long. The voltage used must be the same as specified on this oven. Using a higher voltage may result in a fire or other accident causing oven damage. Using low voltage will cause slow cooking. We are not responsible for damage resulting from use of this oven with a voltage of ampere fuse other than those specified. This appliance is supplied with cable of special type, which, if damaged, must be repaired with cable of same type. Such a cable can be purchased from DAEWOO and must be installed by a Qualified Person. 6. Examine the oven after unpacking for any damage such as: A misaligned door, broken door or a dent in cavity. If any of the above are visible, DO NOT INSTALL, and notify dealer immediately. 7. Do not operate the oven if it is colder than room temperature. (This may occur during delivery in cold weather.) Allow the oven to become room temperature before operating.

EARTHING INSTRUCTIONS
This appliance must be earthed. In the event of an electrical short circuit, earthing reduces the risk of the electric shock by providing an escape wire for the electric current. This appliance is equipped with a cord having a earthing wire with a earthing plug. The plug must be plugged into an outlet that is properly installed and earthed.

WARNING - Improper use of the earthing plug can result in a risk of electric shock. Consult a qualified electrician or serviceman if the earthing instructions are not completely understood, or if doubt exists as to whether the appliance is properly earthed, and either: If it is necessary to use an extension cord, use only a 3-wire extension cord that has a 3blade earthing plug, and a 3-slot receptacle that will accept the plug on the appliance. The marked rating of the extension cord should be equal to or greater than the electrical rating of the appliance, or Do not use an extension cord.

6. DISASSEMBLY AND ASSEMBLY
- Cautions to be observed when trouble shooting.
Unlike many other appliances, the microwave oven is high-voltage, high-current equipment. It is completely safety during normal operation. However, carelessness in servicing the oven can result in an electric shock or possible danger from a short circuit. You are asked to observe the following precautions carefully. 1. Always remove the power plug from the outlet before servicing. 2. Use an insulated screwdriver and ware rubber gloves when servicing the high voltage side. 3. Discharge the high voltage capacitor before touching any oven components or wiring. 1) Check the earthed. Do not operate on a two-wire extension cord. The microwave oven is designed to be used with earthed. It is imperative, therefore, to makes sure it is earthed properly before beginning repair work. 2) Warning about the electric charge in the high voltage capacitor. For about 30 seconds after the operation stopped and electric charge remains in the high voltage capacitor. When replacing or checking parts, short between oven chassis and the negative high terminal of the high voltage capacitor, by using a properly insulated screwdriver to discharge. 4. When the 15A fuse is blown out due to the operation of the monitor switch; replace primary interlock switch, secondary interlock switch and interlock monitor switch. 5. After repair or replacement of parts, make sure that the screws are properly tightened, and all electrical connections are tightened. 6. Do not operate without cabinet. CAUTION : Service personnel should remove their watches whenever working close to or replacing the magnetron.

WARNING : When servicing the appliance, need a care of touching or replacing high potential parts because of electrical shock or exposing microwave. These parts are as follows - HV Transformer, Magnetron, HV Capacitor, HV Diode.

7. INTERLOCK MECHANISM AND ADJUSTMENT
The door lock mechanism is a device which has been specially designed to completely eliminate microwave radiation when the door is opened during operation, and thus to perfectly prevent the danger resulting from the leakage of microwave.

(1) Primary interlock switch
When the door is closed, the hook locks the oven door. If the door is not closed properly, the oven will not operate. When the door is losed, the hook pushes the lock lever downward. The lock lever presses the button of the microswitch. Then the button of the primary interlock switch bring it under "ON" condition.

(2) Secondary interlock switch and interlock monitor switch
When the door is closed, the hook pushes the lock lever downward. The lock lever presses the button of the interlock monitor switch to bring it under "OFF" condition and presses the button of the secondary interlock switch to bring it under "ON" condition.

- Adjustment

Interlock monitor switch
When the door is closed, the interlock monitor switch should be opened before other switches are closed. When the door is opened, the interlock monitor switch should be closed after other switches are opened.

(3) Adjustment steps
(a) Loosen the one mounting screws. (b) Adjust interlock switch assembly position. (c) Make sure that lock lever moves smoothly after adjustment is completed. (d) Tighten completely one mounting screws. NOTE : Microwave emission test should be performed after adjusting interlock mechanism. If the microwave emission exceed 4mW/cm2, readjust interlock mechanism.

9. MEASUREMENT AND TEST
9-1. MEASUREMENT OF THE MICROWAVE POWER OUTPUT
Microwave output power can be checked by indirectly measuring the temperature rise of a certain amount of water exposed to the microwave as directed below.

PROCEDURE
1. 2. 3. Microwave power output measurement is made wit the microwave oven supplied at rated voltage and operated at its maximum microwave power setting with a load of 1000 5cc of potable water. The water is contained in a cylindrical borosilicate glass vessel having a maximum material thickness of 3 mm and an outside diameter of approximately 190 mm. The oven and the empty vessel are at ambient temperature prior to the start of the test. The initial temperature of the water is 10 2 C (50 3.6 F). It is measured immediately before the water is added to the vessel. After addition of the water to the vessel, the load is immediately placed on the center of the shelf, which is in the lowest normal position. Microwave power is switched on. Heating time should be exactly A seconds (Refer to table as following). Heating time is measured while the microwave generator is operating at full power. The filament heat-up time for magnetron is not included. The initial and final temperature of water is selected so that the maximum difference between the ambient and final water temperature is 5K. The microwave power output P in watts is calculated from the following formula: P = 4187 x DT/t DT is difference between initial and ending temperature. t is the heating time. The power measured should be B (Refer to 2. SPECIFICATIONS) W 10.0 %.

4. 5.

6.

7.

CAUTION :
1. 2. 3. Water load should be measured exactly to 1 liters. Input power voltage should be exactly specified voltage (Refer to 2. SPECIFICATIONS). Ambient temperature should be 20 2 C (68 3.6F)

* Heating time for power output: A (second) B (W) 70 600 64 650 60 700 56 750 52 800 49 850 47 900 44 950 42

9-2. MICROWAVE RADIATION TEST
WARNING l l l l l Make sure to check the microwave leakage before and after repair of adjustment. Always start measuring of an unknown field to assure safety for operating personnel from microwave energy. Do not place your hands into any suspected microwave radiation field unless the safe density level is known. Care should be taken not to place the eyes in direct line with the source of microwave energy. Slowly approach the unit under test until the radiometer reads an appreciable microwave leakage from the unit under the test.

PROCEDURE
A) Prepare Microwave Energy Survey Meter, 600cc glass beaker, and glass thermometer 100C (212F ). B) Pour 275cc 15cc of tap water initially at 20 5 C (68 9F) in the 600 cc glass beaker with an inside diameter of approx. 95 mm(3.5 in.). C) Place it at the center of the tray and set it in a cavity. D) Close the door and operate the oven. E) Measure the leakage by using Microwave Energy Survey Meter with dual ranges, set to 2450MHz. - Measured radiation leakage must not exceed the value prescribed below. Leakage for a fully assembled oven with door normally closed must be less than 4mW/cm2. - When measuring the leakage, always use the 5 cm (2 in.) space cone with probe. Hold the probe perpendicular to the cabinet and door. Place the space cone of the probe on the door, cabinet, door seem, door viewing screen, the exhaust air vents and the suction air vents. - Measuring should be in a counter-clockwise direction at a rate of 1 in./sec. If the leakage of the cabinet door seem is unknown, move the probe more slowly. - When measuring near a corner of the door, keep the probe perpendicular to the areas making sure the probe end at the base of the cone does not get closer than 2 in. from any metal. If it does not, erroneous reading may result.

9-3. COMPONENT TEST PROCEDURE
High voltage is present at the high voltage terminal of the high voltage transformer during any cooking cycle. It is neither necessary nor advisable to attempt measurement of the high voltage. Before touching any oven components or wiring, always unplug the oven from its power source and discharge the capacitor.

1. High voltage transformer (A) Remove connections from the transformer terminals and check continuity. (B) Normal readings should be as follows : Secondary winding ... Approx. 100 10% Filament winding ... Approx. 0 Primary winding ... Approx. 1.2 2. High voltage capacitor (A) Check continuity of capacitor with meter on the highest OHM scale. (B) A normal capacitor will show continuity for a short time, and then indicate 10MW once the capacitor charged. (C) A shorted capacitor will show continuous continuity. (D) An open capacitor will show constant 10M (E) Resistance between each terminal and chassis should be infinite. 3. High voltage diode (A) Isolate the diode from the circuit by disconnecting the leads. (B) With the ohmmeter set on the highest resistance scale measure the resistance across the diode terminals. Reverse the meter leads and again observe the resistance reading. Meter with 500V dc or higher voltage batteries should be used to check the front-back resistance of the diode, otherwise an infinite resistance may be read in both directions. A normal diode's resistance will be infinite in one direction and several hundred k in the other direction. 4. Magnetron For complete magnetron diagnosis, refer to "Measurement of the Microwave Output Power." Continuity checks can only indicate and open filament or a shorted magnetron. To diagnose for an open filament or a shorted magnetron, (A) Isolate magnetron from the circuit by disconnecting the leads. (B) A continuity check across magnetron filament terminals should indicate 0.1 or less. (C) A continuity check between each filament terminal and magnetron case should read open. 5. Fuse If the fuse in the primary and monitor switch circuit is blown when the door is opened, check the primary and monitor switch before replacing the blown fuse. In case the fuse is blown by an improper switch operation, replace the defective switch and fuse at the same time. Replace just the fuse if the switches operate normally.
