I received the item in good condition, installed it but I can't calibrate the incline ( no available manual in the parcel ).
Much quicker than expected delivery, easy to install, works perfectly. If you are buying this item, AC + and AC - are your incoming power. M+and M- are your motor plus and minus (DC out). COM I believe is your Earth. Up and Down are for your incline motor. Anyway, that's how I plugged it in and it works great. Thank you! 5 stars - first class!
