3 Replace the magnetron.
Remove the front cover from the
transmitter-receiver unit.
Loosen six front cover screws (M4×10).
Slide the front cover to the upper side,
and then remove it.
Remove two screws (M4×10), and
remove the magnetron cable.
Use a shielded screwdriver for this
work. Contact with metal (tools) can
cause performance degradation in
the magnetron.
Remove four screws (M4×10), and
remove the magnetron.
Use caution not to lose the screws after
removing them.
Install a replacement magnetron and
cables.
Affix the removed insulating tube to
the new magnetron to be installed.
(Recycle this insulating tube. Do
not use the accessory corrugated
tube into the new magnetron.)
After replacing the magnetron, reassemble the unit by following the same steps in reverse order.
Do not forget to tighten the bolts and screws, and do not forget to reconnect the cables.
The above steps complete the magnetron replacement procedure.
