In the Linkage Menu, there is an option called "Model Select".  You go into that.  Rotate the dial to select the desired model.  Press the dial.  You will get "Select" and "Delete".  Select the model.  Once you've changed to that model, the transmitter will take you back to the beginning.  Just continue on and go back into the Linkage Menu, then the "Model Select" function.  The current model is already selected, so just press the dial.  Now you will have "Rename" and "Copy" as your options.  If you have a card installed, you can select the origin and the destination.
