Sounds like it uses a remote I've seen on eBay maybe twice but I can't remember if they had a zoom button. It's a shorter, wider electronic remote whose form factor was commonly used but these had a single volume button. Usually these remotes have volume lo/hi and channel lo/hi buttons side by side. As I recall the single volume button was in one of those rows of two.
