Notes:
 When closing the housing, be careful that the cables are not caught.
 When closing the upper housing, always pull the center of the stay. Otherwise the stay
may be broken.
After the work, turn "ON" the safety switch.
This completes the magnetron replacement procedure.
[Operation check]
1 Turn on the radar, and allow sufficient preheating time (about 20 to 30 minutes in the STBY
state).
2 Start transmission in a short pulse range, and gradually change to longer ranges. At this
time, open the service engineer menu and perform provisional tuning adjustment.
If operation becomes unstable in the meantime, immediately change the equipment back into
the STBY state, leave it there for 5 to 10 minutes, and restart transmission.
3 After long range transmission for about 15 minutes, open the service engineer menu again
and perform tuning adjustment.
In the service engineer menu, perform adjustment for the tune indicator bar on the display to
reach 80%.
In the service engineer menu, also confirm that the magnetron current indicator shows 50 to
70%.
