(1)Prepare 1000 ± 5g tap water.
(2)Adjust water temperature to 10 ± 2℃.
(3)Pour water into a container made of boro‑
silicate Glass,190mm outer diameter
cylinder,maximum 3mm thickness.
Note : Use the container kept on the room
temperature.
(4)Place the container in the center of the
oven cavity.
(5)Set the heating time for 54 seconds and
rating full power and then start microwave
oven.
(6)Take the container out immediately when heat‑
ing time is up.
(7)Stir water for making even water tempera‑
ture in the container.
(8)Measure water temperature.
Water temperature rise should be between
8℃ to 12℃ for correct power output.
(9)For correct Power output measurement,the line
voltage under road must be 230+2volts.

(1)Before the power is applied.
(a)Open and close door several times to
make sure the door interlock switch
and interlock monitor switch operation
properly.(Listen for the clicking sound
from switches.) Make sure the inter‑
lock monitor switch is closed after
the latch interlock switch is open when
the door is opened.
(See pages 1 and 6)
(b)Make sure the perforated screen and
the choke dielectric of the door are
correctly mounted.
(2)After the power is applied.
(a)Open and close the door to see if the
interlock mechanism operates properly.
(b)Check microwave energy leakage with a
leakage detector and confirm the en‑
ergy leakage is below 5mW/cm
(3)Do not operate the unit until it is
completely repaired if any of the following
conditions exists.
(a)Door is not closed firmly against the
cavity front.
(b)The hinge is broken.
(c)The choke dielectric or the door seal
is damaged.
(d)The door is bent or warped,or there is
any other visible damage to the oven
that may cause microwave energy leak‑
age.
Note: Always keep the seal clean.
(e)Make sure that there are no defective
parts in the interlock mechanism.
(f)Make sure that there are no defective
parts in the microwave generating and
transmission assembly.
(especially wave guide)
(4)Folowing items should be checked after
the unit is repaired.
(a)The interlock monitor switch is con‑
nected correctly and firmly.
(b)The magnetron gasket on the magnetron
is properly positioned.
(c)Wave guide and oven cavity are intact.
(No leakage of microwave energy).
(d)The door can be properly closed and the
safety switches work properly.
(e)The oven must be stopped when the door
is opened or the time is up.
The oven must not be operated with any of the
above components removed or bypassed.
HINT FOR LAMP CHANGE
Before removing the bulb access panel, pull
out the main plug. Change the faulty bulb
and secure the bulb access panel. Plug the
