Because each transmitter can be programmed to control up to 20 channels, we normally reprogram the transmitter as we are setting up. After all, despite any marking that are on the throttle, there is no telling how the throttle was used at the last set-up. Programming the throttle is very simple.

First, PRESS AND HOLD the A and B buttons on the transmitter until the green indicator light on the transmitter begins to blink.

Then press the button for the block or receiver that you want the transmitter to control.

We usually only use the letter buttons A through E, although it is possible to use the "Fast", "Slow", directional arrows keys "<-----" and "---->", and "Emergency Stop" buttons.

NOTE: When using the speed, direction, or Emergency Stop buttons, programming on those keys will cause that action to be executed. If you are just setting up, this isn’t a problem. However, if you are running a train and programming on the fly, you could get some unexpected actions, such as your train reversing.

Once you have programmed the transmitter, you can now control two blocks without reprogramming. This is because there is a "Track" switch in the top left corner of the transmitter. For example, if you have programmed the transmitter using button "A", you can control blocks A1 and A2 simply by sliding the track button back and forth. We try and arrange our blocks so that both the "1" and "2" blocks are adjacent. So, how do we arrange our blocks so that the "1" and "2" blocks are adjacent? We program the receivers, too.
