PRECAUTIONS TO BE OBSERVED BEFORE AND DURING SERVICING TO AVOID POSSIBLE EXPOSURE TO EXCESSIVE MICROWAVE ENERGY (a) Do not operate or allow the oven to be operated with the door open. (b) M ake the following safety checks on all ovens to be serviced before activating the m agnetron or other m icrowave source, and m ake repairs as necessary: (1) Interlock operation, (2) Proper door closing, (3) Seal and sealing surfaces (arcing, wear, and other dam age), (4) Dam age to or loosening of hinges and latches, (5) E vidence of dropping or abuse.
SAFETY AND PRECAUTIONS 1. FOR SAFE OPERATION D am age that allow s the m icrow ave energy (that cooks or heats the food) to escape w ill result in poor cooking and m ay cause serious bodily injury to the operator.

INSTALLATION 1. Steady, flat location This m icrow ave oven should be set on a steady, flat surface. This m icrow ave oven is designed for counter top use only. 2. Leave space behind and side A ll air vents should be kept a clearance. If all vents are covered during operation, the oven m ay overheat and, eventually, cause failure.
OPERATIONS AND FUNCTIONS 1. Connect the m ain lead to an electrical outlet. 2. After placing the food in a suitable container, open the oven door and put it on the glass tray. The glass tray m ust always be in place during cooking. 3.
DISASSEMBLY AND ASSEMBLY Cautions to be observed when trouble shooting Unlike many other appliances, the microwave oven is high-voltage, high-current equipment. It is completely safety during normal operation. However, carelessness in servicing the oven can result in an electric shock or possible danger from a short circuit.

INTERLOCK MECHANISM AND ADJUSTMENT The door lock m echanism is a device which has been specially designed to com pletely elim inate m icrowave radiation when the door is opened during operation, and thus to perfectly prevent the danger resulting from the leakage of microwave. (1) Prim ary interlock switch W hen the door is closed, the hook locks the oven door.
TROUBLE SHOOTING GUIDE Following the procedure below to check if the oven is defective or not. 1) Check earthing before trouble checking. 2) Be careful of the high voltage circuit. 3) Discharge the high voltage capacitor. 4) W hen checking the continuity of the switches, fuse or high voltage transform er, disconnect one lead wire from these parts and check continuity with the AC plug removed.

MEASUREMENT AND TEST 1. MEASUREMENT OF THE MICROWAVE POWER OUTPUT M icrowave output power can be checked by indirectly m easuring the tem perature rise of a certain am ount of water exposed to the m icrowave as directed below. PROCEDURE 1.
2. MICROWAVE RADIATION TEST CAUTION 1. M ake sure to check the m icrowave leakage before and after repair of adjustm ent. 2. Always start m easuring of an unknown field to assure safety for operating personnel from m icrowave energy. 3.
MEASUREMENT AND TEST 3. COMPONENT TEST PROCEDURE High voltage is present at the high voltage term inal of the high voltage transform er during any cooking cycle. It is neither necessary nor advisable to attem pt m easurem ent of the high voltage. Before touching any oven components or wiring, always unplug the oven from its power source and discharge the capacitor.
