INTERLOCK MECHANISM AND ADJUSTME NT 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 sw itc h
When the doo r is clos e d, the h o ok lock s the ove n door. If th e door i s n o t closed prope rl y, th e oven w ill not op erate.

When the door is closed, the interlock monitor switch should be changed(NO condition) before other switches are closed.
When the door is opened, the interlock monitor switch should be changed(NC condition) after other switches are opened.
NOTE
Microwave emission test should be performed after adjusting interlock mechanism. If the microwave emission exceed
4mW/cm

, readjust interlock mechanism.
