* Joystick callibration:
1. Place the key on the upper control and unlock the emergency stops. (do not start)
2. Unplug the joystick you want to calibrate for 10sec.
3. Operate the joystick maximum and hold it for 5 sec. stretched out.
4. Operate the joystick for 1 sec. in rust.
5. Operate the joystick to the maximum in the other position, hold it for 5 sec. stretched out.
6. If the calibration is successful, a beep will sound.

sorry for the bad translation, hope it works
