CAUTION

WARNING TO SERVICE TECHNICIANS

To avoid possible exposure to microwave ra- diation or energy, visually check the oven for damage to the door and door seal before operating the oven. Use your microwave sur- vey meter to check the amount of leakage before servicing. In the event that the R.F. Ieakage exceeds 4 mw/cm2 at 5 cm, appropri- ate repair must be made before continuing to service the unit. Check interlock function by operating the door latch. The oven cook cycle should cut off before the door can be opened.

The door and latching assembly contains the radio frequency energy within the oven. The door is protected by three safety interlock switches. Do not attempt to defeat them. Un- der no circumstances should you try to oper- ate the oven with the door open.

•Proper operation of the microwave ovens requires that the magnetron be properly assembled to the waveguide and cavity. Never operate the magnetron unless it is properly installed.

•Be sure the “RF” seal is not damaged, and assembled around the magnetron dome properly when installing the magnetron.

•Routine service safety procedures should be exercised at all times.

•Untrained personnel should not attempt service without a thorough review of the test procedures and safety information contained in this manual.

PRECAUTIONS TO BE OBSERVED BEFORE AND DUR- ING SERVICING TO AVOID POSSIBLE EXPOSURE TO EXCESSIVE MICROWAVE ENERGY.

1.Do not operate or allow the oven to be operated with the door open.

2.Make the following safety checks on all ovens to be serviced before activating the magnetron or other microwave source, and make repairs as necessary:

a)Interlock Operation.

b)Proper Door Closing.

c)Seal and Sealing Surfaces (Arcing, Wear, and Other Damage).

d)Damage to or Loosening of Hinges and Latches.

e)Evidence of Dropping or Abuse.

3.Before turning on microwave power for any service test or inspection within the microwave generating compartments,

check the magnetron, wave guide or trans- mission line, and cavity for proper align- ment, integrity, and connections.

4.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.

5.A microwave leakage check to verify com- pliance with the Federal performance standard should be performed on each oven prior to release to the owner.
