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 power to the microwave oven 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.

INSTALLATION
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 oven failure.
3. Away from Radio and TV sets
Poor television reception and radio interference may result if the oven is located closed to a TV, Radio, antenna or feeder
and so on.
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 11 amperes, 230Volts, 50Hz grounded outlet.
Power supply cord is about 1.4 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 amprer fuse other than those specified.
This appliance is supplied with cable of special type, which, if samaged, 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 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 applicance is equipped with a cord having a reathing wire with a
earthing plug. The plug must be plugged into an outlet that is properly installed ant 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 3-blade earthing plug, and a
3-slot receptacle that will accpt 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.

OPERATIONS AND FUNCTIONS
1. Connect the main lead to an electrical outlet.
2. After placing the food in a suitable container,
open the oven door and put it on the glass tray.
The glass tray must always be in place during cooking.
3. Close the door securely.
4. Choose cooking power level by setting V.P.C knob to
the desired position.
5. Determine cooking time. Consult cookbook for recipe timing.
Oven light turns on and cooling fan starts to operate.
Microwave cooking starts.
6. You may open the door while the oven is operating.
As soon as the door is opened, the safety mechanisms stop the
generation of microwave power and the operation of cooking
timer. If you wish to change the time during cooking,
simply adujst the timer to the desired time.
7. When the timer reaches zero, a bell will ring and the unit will turn
off. Oven light turns off. If additional cooking time is needed and
the door is closed, the oven will automatically start when the timer is reset.
NOTE
1. When setting timer for less than 2 minutes, turn the
timer pass 2 minutes and then return to the correct
timer setting.
2. Various clicking noises may be heard when turning
V.P.C knob. This is normal and does not affect the
operation of your microwave oven.
To set MICROWAVE cooking
Set the variable power selector to the desired power level.
POWER LEVEL SYMBOL APPROXIMATE PERCENTAGE OF POWER
HIGH MAX 100%
MED-HIGH 700W 88%
MEDIUM 580W 73%
DEFROST 41%
HEAT 26%
To set GRILL cooking
Set the POWER SELECTOR to the (grill) position.
To set COMBI cooking
Set the POWER SELECTOR to the (combi) position.
NOTE
When using the GRILL or COMBI mode;
Do not open the door so open, the temperature inside the oven decrese and the cooking may not be completed in setting time.
Never touch the oven window and metal interior of the oven when taking food in and out, because the temperature inside the
oven and door is very high.
When using these mides, be careful as the tray will be hot to touch, use oven gloves or pot holders while handling tray.

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 scredriver and ware rubber gloves when servicing the high voltage side.
3. Discahrge the high voltage capacitor before touching any oven components or wiring.
(1) Check the grounding.
Do not operate on a 2-wire extension cord.
The microwave oven is designed to be used with grounded.
It is imperative, therefore, to make sure it is grounded 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.
CAUTION : When servicing th 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,
HV Fuse.
