in, that the signal/control lines are connected, and that both the measuring instrument and the external
LO

Operator Maintenance
The only maintenance needed by the Microwave Converter is replacement of the primary power fuse.

counterclockwise (while pushing with a slight pressure) until the fuseholder is released. Remove and
replace the fuse with
a
new fuse of identical value.
