BuzzTV BT-100 doesn't stay connected to Bluetooth

[Applefish]

Hi all. Maybe someone can help me here. I bought a XRS4500 max last month and I'm pretty happy with it. It came with a BuzzTV BT-100 remote. I can pair it pretty easily, but it disconnects from the box shortly after. I tried to connect it again before going to bed yesterday evening and leave it besides the box which I left turned on. It was still disconnected this morning. Is it the remote? The box? The drivers?

I bought this box to be able to tuck it behind the tv on the wall and be able to use it while hidden. But that can't happen now.

When you say it's disconnected and go to remotes and accessories is the bt100 listed?

Yes. It easily connect to the XRS4500. When I go back in, it is just listed, but not connected. I have to unpair it, then pair it again. But it doesn't last at all.

You sure it's disconnected?

The remote does go to sleep and needs some time to wake

Yes. I use it in RF mode all the time as it disconnects. The way I know that it is disconnected is that the mouse pointer is slow in RF mode but blazing fast in Bluetooth mode.
