PROPER USE AND PRECAUTIONS
1. For Safe Operation
Damage that allows the microwave energy (that cooks or
heats the food) to escape will result in poor cooking and
may Cause serious bodily injury to the operator.
IF ANY OF THE FOLLOWING CONDITONS EXIST,
OPERATOR MUST NOT USE THIS APPLIANCE.
(Only a trained serviceman should make repairs.)
(1) A broken door hinge.
(2) A broken door mesh plate.
(3) A broken front panel, oven cavity.
(4) A loosened door lock.
(5) A broken door lock.
The door gasket plate and, oven cavity surface should be
kept clean.
No grease, soil or spatter should be allowed to build up on
these surfaces or inside the oven.
DO NO ATTEMPT TO OPERATE THIS APPLIANCE
WITH THE DOOR OPEN. The microwave oven has con-
cealed switches to make sure the power is turned off when
the door is opened. Do not attempt to defeat them.
DO NOT ATTEMPT TO SERVICE THIS APPLIANCE
UNTIL YOU HAVE READ THIS SERVICE MANUAL.
2. Correct Installation
(1) This microwave Oven weights 29 kg and must be
placed on a horizontal base strong enough to support
this weight.
(2) The Oven should be placed as far from high tempera-
ture heat source and vapour as possible.
(3) The power supply cord is 1.8 m_ long.
Grounding is required when connecting the power
source.
(4) Power consumption of this oven is approximately
2.0 kW. It is suggested that the unit is operated on
such power line that can provide more power than this
rating.
Objects must not be placed on the top enclosure so as
not to obstruct air flow for ventilation.

MEMORY
This oven employs the memory function which is available
to enter 7 kinds of the cooking processes, using with the
MEMORY pad and one of the NUMBER pads
<—
This is convenient tor the repeatable cooking.
TO SET MEMORY with an example;
1. Touch FULL pad
2. Set the timer to 1 min. 30 sec.
3. Touch the NUMBER pad [_1 |
A dot on the corner in the number pad will light up.
4. Touch MEMORY pad
The cooking process with FULL power for 1 min. 30 sec.
was entered into the NUMBER pad [ 1] . The other
cooking processes can be memorized into the each NUM-
BER pad with the same steps.
TO USE MEMORY
1. Touch the NUMBER pad [1 |
A dot in the number pad ["1] will light up and the
memorized cooking process, the power level and the
cooking time, will appear in the display window.
2. Touch the START pad
The oven will start the cooking process which is mem-
orized.
TO CHANGE MEMORY
The memory cannot be cleared or changed even by touch-
ing the CLEAR pad [0] , except when the new cooking
process with the same steps in ‘TO SET MEMORY’ is
entered,
1. Set the power level.

INTERLOCK MECHANISM FUNCTIONS AND ADJUSTMENTS
The door lock mechanism is a device which has been
specially designed to completely eliminate microwave radia-
tion when the door is opened during cooking, and thus to
perfectly prevent the danger resulting from the leakege of
microwave.
Whenever the door lock mechanism is repaired, check
microwave leakage according to the procedure specified
in page 19.
1. Mechanical Function
When the door is closed, the catch under the door handle
snaps on the latch on the oven, locking the oven door. If
the door is not closed properly, the oven will not operate.
Fig. 4 shows the closed door condition.
When the door is closed, the lower catch pushed the slider
of the interlock monitor switch to bring it “OFF” condi-
tion, then the catches, upper and lower, individually
engage with the latch and the tip of the catches pushes the
lever which presses the button of the primary/secondary
interlock switch to bring them under “ON” condition.

When the handle is pulled to open the door, as illustrated
in Fig. 5, the catches disengage from the latch, leaving the
lever in a free state, thus the lever is pushed by the switch
button to turn off the switch and open the circuit. Then
the lower catch releases the slider to bring the interlock
Monitor switch under “ON” condition.
