While you can program the transmitters on the fly, you have to be very careful when programming the receiver. Any button on the transmitter programs the receiver. Once you start this process on a receiver, it will accept whatever signal it next receives as its identification. So, make sure that no one is trying to run trains with a transmitter at the same time that you are programming the receivers.

You also need to check the position of the "Track" switch on the transmitter. If you are trying to program a receiver as Block A1, throw the track switch to "1".

STEP 1: PRESS AND HOLD the A and B buttons on the transmitter until the green indicator light on the transmitter begins to blink.

STEP 2: Then press the button for the block or receiver that you want the transmitter to control.

STEP 3: Press and hold the "CODE SET" button on the receiver, until the light on the receiver begins to flash.

STEP 4: Press any button on the receiver and the "CODE SET" light will go out.

The receiver is programmed.
