15.5.2 Replacement of magnetron
When replacing magnetrons, make sure to shut off the main power and let the
equipment stand for more than 5 minutes to discharge the high-voltage circuit.
Failure may result in electric shock.
Make sure to take off your watch when your hand must get close to the
magnetron.
Failure may result in damage to the watch since the magnetron is a strong
magnet.
Memo
Replacement of magnetron must be made by a specialized service personnel.
For details, refer to Service Manual.
Use necessarily the parts to meet the part types in the above shown in the table.
Do not touch the magnet of the magnetron with a screwdriver or put the magnetron on an iron plate.
When replacing the magnetron, connect the lead wire correctly.
15.5.2.1 Handling of magnetron under long-time storage
The magnetron that has been kept in storage for a long time may cause sparks and operate unstably
when its operation is started. Perform the aging in the following procedures:
Warm up the cathode for a longer time than usually. (20 to 30 minutes in the standby
state.)
Start the operation from the short pulse range and shift it gradually to the longer pulse ranges.
If the operation becomes unstable during this process, return it to the “Standby” state immediately.
Keep the state for 5 to 10 minutes and then repeat this procedure.
