There are only two menus in the linking and cab number process. You
start by selecting a linking number (00 to 49), then type in the
locomotive name and road number. (00) is recommended for the first
locomotive, (01) for the second, etc.
To perform the linking process you scroll down the menu to the linking
selection.
You should plug in the code set link cord into the 3 prong socket.
Alternatively, you can press the black button directly at the corner of
the receiver as shown.
