H.REMOVING DOOR

I.HOW TO RESET THE MEMORY OF ACCUMU-
  LATIVE COOKING TIME

1. Push the keys step by step as follows,
   Turn the Timer Knob to left until display shows“0”.
   Touch START key first and also touch POWER
   SELLECTION key (1800W) until display changes.
   The display will show accumulative cooking time
   in the display window.

2. Then push the POWER SELLECTION key(1800W)
    during cooking time appear in the display.

3. Push the POWER SELLECTION key(1800W) for

J.CAUTION FOR CUSTOMER ON OPENING
   AND CLOSING DOOR
 

  When the Microwave oven is in operation, should

   the customer open the door slightly and close, the
   breaker of the house will occasionally be cut off.
   It is necessary to explain to the customer not to
   exercise such matter.
   When the Door is opened slightly between 2 or 3
   mm distance, primary interlock switch turn OFF,
   and operation stops.
   However door sensing switch will remain ON, and
   if door is closed, primary interlock switch activates
   and operation resumes immediately.
   At such time microwave oven  will start any time.
   Therefore a big In-rush currnet flows, and thus
   Breaker will be cut off.
