The slide gates for LiveO2-AC and ExtremeO2 are designed to close properly when the cable is uncoiled.
When the cable is coiled, the cable is bunched up inside causing the gate not to align properly. If your cable is uncoiled, and the gate isn’t aligning, then there may have been a yank that changed the alignment, don’t worry, here’s a video that shows how to repair it…
