CAUTION
MICROWAVE RADIATION
PERSONNEL SHOULD NOT BE EXPOSED TO THE
MICROWAVE ENERGY WHICH MAY RADIATE
FROM THE MAGNETRON OR OTHER MICRO-
WAVE GENERATING DEVICE IF IT IS impro-
perly USED OR CONNECTED. ALL INPUT AND
OUTPUT MICROWAVE CONNECTIONS, WAVE-
GUIDES, FLANGES, AND GASKETS MUST BE
SECURE. NEVER OPERATE THE DEVICE WITH-
OUT AMICROWAVE ENERGY ABSORBING
LOAD AlT’ACHED. NEVER LOOK INTO AN
OPEN WAVEGUIDE OR ANTENNA WHILE THE
DEVICE IS ENERGIZED.
1. ADJUSTMENT PROCEDURES
TO AVOID POSSIBLE EXPOSURE TO MICROWAVE
ENERGY LEAKAGE, THE FOLLOWING ADJUST-
MENT OF THE INTERLOCK SWITCHES SHOULD BE
MADE ONLY BY AUTHORIZED SERVICE PERSON-
NEL.

Loosen 2screws securing the lever stopper.
Adjust the lever stopper position so that it is
pushed forward and pull backward until the Ac-
tuators are just at the lowest end of their stroke on
the Latch Interlock Switch and Door Interlock
Switch, and at the same time there is about zero
gap between the Latch Lever and the Switch Body
on the Interlock Monitor Switch and Door Sensing
Switch when the Door Latch is securely locked.
Tighten the Lever Stopper screws securely.
Make sure the Interlock Monitor Switch closes
after the Latch Interlock Switch opens when
the door is opened very slowly, according to
“CHECKOUT PROCEDURE FOR SWITCHES”
on page 6.
Make sure the Interlock Monitor Switch opens
before the Latch Interlock Switch closes when the
door is closed very slowly, according to “CHECK-
OUT PROCEDURE FOR SWITCHES” on page 8.
(6) Make sure the microwave energy l~akage IS be!ow
the limit of the regulations (bmV!/crn - ) when
measured with adetector.
