my transmitter has been changed sothat i cant operate the robot by the Aracde-4 now i juet want to reset the transmitter who knows what should i do
It’s in the Vex manual how to reset the transmitter and how to change the modes arcade , tank etc.
If you don’t have it handy you can download the manual from this link.
http://www.vexrobotics.com/vex-robotics-downloads.shtml
The sections you want are the “control " section and appendix “E” - Transmitter Menus”
Make sure you download from the 2008 manual.
If after reading these sections you still don’t understand people can help with problems you are still having.
Give it a go because you can’t damage the transmitter by getting it wrong.
You can always do a default reset.
