[R-390] R-391 Set-up

[Rick Popovich]

Thanks to all who have responded, the link to the manual is exactly what
I needed, I have already started getting familiar with the various
connections and operating steps/ procedures.

Hopefully in a few more days I can give it a go and see how the
auto-tune works - if it works. I will be taking my time on this step to
avoid any mistakes.

Best regards and many thanks!

Not exactly, as I remember.  (I have not checked the manuals).

As I remember, the 28 volt supply is brought in from the main AC supply
connector, along with the 115 volt line current,

Th other multiple pin connector is used to REMOTELY select any of the
pre-set frequencies.  Without checking the manuals, I don't know how the
system is set up to not respond to the local channel switch.
