Clear button assignment on Graupner MZ-12

[TanelF]

Hello everyone I built the Versacopter v.2 and programmed Graupner MZ-12 transmitter, but I accidentally assigned the wrong button on the transmitter to start the timer. I'm looking for a way to clear the button assignment... anyone know how to do that?

The only way I'm aware of is to assign it to a different switch. Maybe your throttle stick would be an easy way to measure.
