I've recharged the remote and slides 2 and 4 still do not extend or retract with the remote. I can hear a switch clicking. They will work with the control panel. Everything else works with the remote slides 1 and 3, both awnings, and lights.
I suggest not using the remote for Schwintek slides. Use it for everything else but those. Why? If you stop before full travel (and holding it engaged after it stops to set or confirm the stop point) you run the risk of putting the slide out of sync and timing. The remotes have a really good chance of cutting out, and this will impact the successful operation of the slides. Just a recommendation.
