GENERAL INFORMATION FOR SERVICE
GENERAL PRECAUTIONS IN USE
A.Never operate the unit when it is empty. Operating the oven with no load may shorten the life of the magnetron. Whenever cooking dry foods (dried fish, bread, etc.) or a small amount of food, be sure to put a glass of water into the cooking compartment. The glass turntable may become hot after operating, be careful when touching it.
B.Aluminum foil should be avoided because it will disrupt cooking and may cause arcing. However, small pieces may be used to cover some parts of food to slow the cooking. Any aluminum foil used should never be closer than 2.5 cm to any side wall of the oven.
TRIAL OPERATION
After installation, the following sequences and results should be checked carefully.
A.Put a container filled with water (about 1 liter) into the oven, and close the door tightly.
B.Set cooking time for 10 minutes by touching “1” and then “0” three times. “1, 0, 0, 0” appears in the display window.
C.Touch the START key.
Make sure the cavity light comes on. The unit will begin cooking and the display window will show the time counting down by seconds.
D.After about 5 minutes, make sure the primary interlock switch, the secondary interlock switch and the interlock monitor switch operate properly by opening and closing the door several times. Touch the START key each time the door is closed.
E.Continue operating the unit. Four long beep sound signal is heard when the time is up. The unit will shut off automatically.
F.Confirm the water is hot.
G.Finally, measure the output power according to “POWER OUTPUT MEASUREMENT” on page
