Billsrr postedTried the aux 2 holding down and no new screen happened.
It isn't the screen that shows the engine numbers, it is more properly the keypad icons that will change. Sorry, I didn't make that clear. If I select any engine that I have entered into the remote (makes no difference what type of lighting effect they have) and hold down Aux2, keypad icons change from the ones that has the smoke icon to a new set that shows various kinds of lights. The engine does not have to have be powered up. I am using v1.61 on remote and v1.60 on the base.
