Don't know how to help you, except suggest to take to your closest dealership.
I don't think I've ever heard of slides operating with a remote. Kind of scary if you ask me.
At home, we've had the television come on and off by itself, and channels changed. Different televisions of course. We once had a garage door that automatically opened or shut on its own. We've had the panic alarm go off on car once when absolutely no one was around. We had a fan in one house that would turn on by itself.
What did all of these things have in common? They all had a remote. We figure, somehow, they were getting a signal from somewhere, just the right frequency to operate a specific function.
I can just see it! You're all snugged in bed at night when all of a sudden the slide your bed is on starts retracting. Squish, squash! There goes the wife. She just slid under the vanity!
Technology! It's wonderful when it works right, it's He!! when it don't!
