Please make sure there is only 1 wireless receiver plugged into your track.  This receiver should be plugged in to either the 1^st or 2^nd tower on your control unit.

Step 1- Take all the cars off of the track

Take "controller 1" and hit the set button on the receiver, when you see the #1, press the black button on top of your controller

Take the "car 1" and put it on the track.

Press the code button once and then press the trigger on your controller.  Car 1 should now be coded to controller 1.

Step 2-

Take car 1 off the track

Take "controller 2" and hit the set button twice on the receiver, when you see the #2, press the black button on top of your controller. 

Take the "car 2" and put it on the track.

Press the code button once and then press the trigger on your controller.  Car 2 should now be coded to controller 2.

Step 3 -

Take car 2 off the track

Take "controller 3" and hit the set button twice on the receiver, when you see the #3, press the black button on top of your controller. 

Take the "car 3" and put it on the track.

Press the code button once and then press the trigger on your controller.  Car 3 should now be coded to controller 3.

Follow the same steps for the remaining cars/controllers.

You will not need to do this before every race; each car will stay coded to its controller.  You should now be set to race
