I bought this device recently and while it looks nice, there are no instruction manuals except for a once sided sheet of paper that tells you how to install it. Notably, on this one sheet of paper, it instructs you to set a dip switch that doesn't exist. This model lacks a full and complete manual on how to set up and how to install. Very challenging to setup as I had to reach out to two very experienced amateur radio operators to try and help get this working.
Note from Admin: The instructions for the FC50 are in the FT-891 advanced instruction manual.
