1. ADJUSTMENT PROCEDURES
TO AVOID POSSIBLE EXPOSURE TO MICRO-WAVE
ENERGY LEAKAGE, THE FOLLOWING ADJUST-
MENT OF THE INTERLOCK SWITCHES SHOULD
BE MADE ONLY BY AUTHORISED SERVICE
PERSONNEL
PRIMARY INTERLOCK SWITCH, DOOR SENSING
SWITCH AND INTERLOCK MONITOR SWITCH
ADJUSTMENT
(Figure 1)
(1) Loosen 2 screws securing the lever stopper.
(2) Adjust the lever stopper position so that it is pushed
up and pull forward until there is about zero gap.
2-1. Between the lever and the switch body on
the door sensing switch.
2-2. Between the lever and the switch body
on the interlock monitor switch.
2-3. Between the latch lever and the switch body
on the primary interlock switch.
when the door latch is securely locked.
(3) Tighten the lever stopper screws securely.
(4) Make sure the interlock monitor is closed after
the primary interlock switch opens when the door is
opened very slowly, according to “CHECKOUT
PROCEDURE FOR SWITCHES” on page 9.
(5) Make sure the interlock monitor is open before
the primary interlock and secondary interlock
switches close when the door is closed very slowly,
according to “CHECKOUT PROCEDURE FOR
SWITCHES” on page 9.
(6) Make sure the microwave energy leakage is below
the limit of the regulation (5mW/cm
2
) when
measured with a detector. ( All service
adjustments must be made for minimum energy
leakage readings.)

CAUTION
MICROWAVE ENERGY
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, WAVE GUIDES, FLANGES, AND GAS-
KETS MUST BE SECURE. NEVER OPERATE
THE DEVICE WITHOUT A MICROWAVE ENER-
GY ABSORBING LOAD ATTACHED. NEVER
LOOK INTO AN OPEN WAVE GUIDE OR
ANTENNA WHILE THE DEVICE IS ENERGISED.
