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) Make the following safety checks on all ovens to be serviced before activating the magnetron or other

microwave source, and make repairs as necessary : (1) Interlock operation, (2) proper door closing, (3) seal and sealing surfaces (arcing, wear, and other damage), (4) damage to or loosening of hinges and latches, (5) evidence of dropping or abuse.

compartments, check the magnetron, wave guide or transmission line, and cavity for proper alignment, integrity, and connections.

(d) Any defective or misadjusted components in the interlock, monitor, door seal, and microwave generation and

transmission systems shall be repaired, replaced, or adjusted by procedures described in this manual before the oven is released to the owner.

(e) A microwave leakage check to verify compliance with the Federal per formance standard should be performed

on each oven prior to release to the owner.

The following U.S. standard applies to microwave ovens : 21 CFR 1030.10, Performance Standard for Microwave Ovens.

It requires that the power density of the microwave radiation emitted by a microwave oven shall not exceed five (5) milliwatts per square centimeter at any point 5 centimeter (about 2 inches) or more from the external surface of the oven.

All microwave ovens exceeding the emission level of 4mW/cm microwave ovens and the manufacturer immediately and the owner should be told not to use the microwave oven until it has been repaired completely.

If a microwave oven is found to operate with the door open, report to Dept. of Service, the manufacturer and CDRH* immediately. Also tell the owner not to use the oven. *CDRH : Center for Device and Radiological Health.

The interlock monitor switch acts as the final safety switch protecting the customer from microwave radiation. If the interlock monitor switch operates to blow the fuse with interlocks failed, you must replace all interlock switches primary and secondary interlock switches and the monitor switch with new ones because the contacts of those interlock switches may be melted and welded together.

two (2) minutes.

(D) 1. Take out the two bowls at once.

2 . Stir both water with thermometer and measure the

water temperature rise respectively.

(E) 1 . Get temperature rise by calculation the difference

(water temperature after cooking minus initial temperature) in each bowl.

2 . Then calculate average value(t) of both temperature

rises in degrees centigrade.

The Power Output specification 600W on this model is measured with IEC measurement. The Power Output is measured with two (2) liters water is equivalent to 600W in measurement with IEC, when measured with the following power output.

(A) 1 . Fill two test bowls with each 1 liter water respectively.

2 . Use accurate thermometer and measure each

(B) Place the two bowls on glass turntable.

Where ∆t is an Average Temperature Rise in degrees centigrade.
