I inherited a 6XA transmitter. I downloaded the manual to learn how to program it. First, it seems to work OK -- sticks move appropriate servos. Trims works, etc.

To enter programming mode, the instructions say to power up, and then hold down both MODE buttons. After that, press the MODE Down button to scroll thru the menu choices. When both buttons are pressed, all it does is toggle from TREV to ATV, and no other buttons work (+ or -), or cause changes. I cannot get to settings like servo reversal, etc.

Upon furhter tries, I found out that pressing either MODE button causes the above, it does not require holding both down.

Any advice would be great!

Thanks,

Lee
