CAUTION
MICROWAVE RADIATION
PERSONNEL SHOULD NOT BE EXPOSED TO
THE MICROWAVE ENERGY WHICH MAY RADI-
ATE FROM THE MAGNETRON OR OTHER
MICROWAVE GENERATING DEVICE IF IT IS
IMPROPERLY USED OR CONNECTED. ALL
INPUT AND OUTPUT MICROWAVE CONNEC-
TIONS, WAVEGUIDE, FLANGES, AND GASKETS
MUST BE SECURE. NEVER OPERATE THE
DEVICE WITHOUT A MICROWAVE ENERGY
ABSORBING LOARD ATTACHED. NEVER LOOK
AN OPEN WAVEGUIDE OR ANTENNA WHIL THE
DEVICE IS ENERGIZED.

1. ADJUSTMENT PROCEDURES

TO AVOID POSSIBLE EXPOSURE TO MICROWAVE
ENERGY LEAKAGE, THE FOLLOWING ADJUST-
MENTS OF THE INTERLOCK SWITCHES SHOULD
BE MADE ONLY BY AUTHORIZED SERVICE PER-
SONNEL.
A.INTERLOCK SWITCH AND DOOR SENSING
SWITCH ADJUSTMENT(Figure 1-a)
(1) Loosen 2 screws securing the lever stopper.
(2) Adjust the lever stopper position so that it is pushed
up and rotated counterclockwise until there is zero
gap between the latch lever and the switch bodies
when the door latch is securely locked.
(3) Tighten the lever stopper screws securely.
(4) Make sure the latch interlock switch and the door
sensing switch open before the interlock monitor
switches coses when the door is opened very
slowly, according to "CHECKOUT PROCEDURE
FOR SWITCHES" on page 6.
(5)Make sure the microwave energy leakage is below
the limit of the reguration5 mW/cm
measured with a detector.
(All service adjustments must be made for mini-
mum microwave energy leakage readings.)
B.LATCH INTERLOCK SWITCHES ADJUSTMENT
(Figure 1-b)
(1) Loosen 2 screws securing the lever stopper.
(2) Adjust the lever stopper position so that it is pushed
