H.REMOVING DOOR

NOTES
-  After replacing the door, be sure to check that the
   interlock switch, the door sensing switch
   and the interlock monitor swich operate normally.
   (See pages 1 and 6)
-  After replacing the door, check for microwave ene-
   rgy leakage with a leakage detector. Microwave
   energy leakage must be below the limit of
   5mW/c

‡u.

 

(For US)

-  After instaling the door,  check for microwave
   energy with a leakage detector and confirm that the
   leakage is the below the limit of 1 mW/cm

2

 (at 275cc

   waterload),5 mW/cm

 (at no load) and  5 mW/cm

2

    

(at 275cc water load without cabinet)  . (For CANADA)

I.HOW TO RESET THE MEMORY OF ACCUMU-
  LATIVE COOKING TIME
1. Push the keys step by step as follows,
   “  CLEAR   “, “ TIME  “, “ 8 “, “ 8 “, “ 8 “, “ 1 “
   “ START  “, “ START   “.
   The display will show accumulative cooking time
   in display window.

2. Then push the keys as follows.
   “ 0 “,    “ MEMORY  “.
   The Memory of Accumulative cooking time will be
   cleared.

J.RELEASING TYPE CONNECTOR

 This oven is provided with locked type connectors.
 When you remove a connector, pull the connector while
 releasing the lock by pressing “A” point shown below.
