Hello. I hope this won't be a pain for someone to do for me. I've looked at the manual for csx at the multiple unit settings and I'm struggling. I've tried all the settings in the manual but every time I've took the brake of the one I want to lead it starts moving without me touching the throttle. I have learning difficulties and asperges and been trying to solve this problem for 2 days now. Is it possible for someone to do the settings via pictures for me on how to swap back and forth between multiple units. This would be a big help and much appreciated. Steven
