Step 2 - Fit Decoder
Orientate the decoder so that the side with two contact points at the top and bottom is showing, and the small black chip is towards the back of the model.
Slide the decoder in, making sure it goes all the way in and that it is over the copper spring, not below.
Step 3 - Refit Decoder Cover
Clip the decoder cover back on, and test it on your programming track.
