When using the default program, you can only do left and right fine-tuning in the smallest disk, and the position in the fine-tuning mode. The eds transmission defaults to the smallest sprocket.

n is the gear mode, t is the fine-tuning mode, and the fine-tuning mode is used to adjust the transmission when we use the default program. In  t fine-tuning mode, you can use the controller up and down to fine-tune the minimum disk to complete the speed change adjustment, and then turn back to the n-gear mode to complete the tuning.
