[Premium-Rx] Instrution Manual

[Marco IK1ODO]

For what I remember of Rycom equipment, I agree with Nigel. The power 
transformer has a single primary, you need to replace it or use an 
autotransformer.
Look at the transformer, if it has only two wires on the primary side 
there is nothing you can do :-)
