(4) Remove the eight screws (M6) to
remove the fixture holding the
magnetron. The screws cannot be
removed from the fixture, so loosen the
all eight screws and remove the
magnetron together with the fixture.
The magnetron is held by a hook, but be careful
not to let it fall.
Use a shielded screwdriver. If the magnetron
comes into contact with any metal (tool), its
performance may deteriorate.
(5) After having replaced the magnetron, reassemble the unit by following the
disassembly procedure in the reverse order.
Do not forget to tighten the bolts and screws, and do not forget to reconnect the
cables.
Make sure that there is no foreign matter or dust adhered to the gasket when you
put the cover on.
Extreme care should be taken to connect the leads (yellow and green) to the magnetron for prevention of
contact with other parts or the casing. Contact may cause them to discharge.
(6) Turn on the safety switch (do not forget to put the cover back on).
(7) Turn on the radar power supply and check that the system works properly.
