Thanks for contacting us on the forums! I was looking our list, and I was seeing some options for Maximum. I don't see anything for your model, but I would try a few remote in the list to see if one might work. I would just type in Maximum and try the remotes that come up. If there isn't a remote that works for your cable box, we do have a place on this forums for remote control requests.
