If it's as it is, from the factory, it will probably just be loaded with the original VU+ image:

You should really load a different image, like Black Hole, Open Black Hole, Open Vix, or other, try to find out which works best with opening the channels on 27.5W.
If you do this you will lose all your current data.
You can back up your channel list, and Bouquets, using software like dreamboxedit.

The VU+ Zero was never really designed as a stand alone receiver, more as a second, networked, receiver, so it hasn't got the power, or capabilities, of some of the other receivers, it can't even run the full KODI.
You can check its components on the VU+ website, scroll to the bottom, of the link, to the table comparing various VU+ receivers:
