PRECAUTIONS
SINCE NEARLY 2,100 VOLTS EXISTS IN SOME
CIRCUITS OF THIS UNIT REPAIRS SHOULD BE CARRIED OUT WITH GREAT CARE.
The filament leads of magnetron carry High Voltage with respect to ground. Extreme caution must be exercised. Never plug the unit into a power source to determine which component is defective in high voltage section.

> Before the power is applied; (a)
Make sure the primary interlock switch, the secondary interlock switch and the
interlock monitor switch operate properly by opening and closing the door
several by opening and closing the door several times. (b) Make sure the perforated screen and the
dielectric choke of the door are correctly and firmly mounted.
> After power is applied; (a) Make sure the interlock switch mechanism is operating properly by opening and closing the door. (b) Check microwave energy leakage must
be below the limit of 5 mW/cm2 (All service adjustments should be made for minimum microwave energy leakage readings).

be below the limit of 5 mW/cm2 (All service adjustments should be made for minimum microwave energy leakage readings).
> Do not operate the unit until
it is completely repaired, if any of the following conditions exist. The unit must not be operated. (a) The door does not close firmly. (b) The hinge is broken. (c) The door seal is damaged. (d) The door is bent or warped, or there is
any other visible damage on the unit that may cause microwave energy leakage. [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 detective
parts in the microwave generating and transmission assembly (especially wave-guide).
> The following items should be
checked after the unit is repaired.
(a) The interlock monitor switch is connected correctly and firmly.
(b) The magnetron gasket is properly positioned and mounted.
(c) The waveguide and the oven cavity are intact.(no microwave energy leakage)
(d) The door can be properly closed and the safety switches work properly.
(e) The unit must stop when the door is opened or the time is up.
The unit must not be operated with any of the above components removed or by-passed.
