I'd suggest you learn how to use the SkyDemon, what its functions do, how they are displayed, etc, before just "using" it. A bit like, "I'm learning to fly in a Cessna 152 and I found a lever in a quadrant on the panel that moves up and down, what is this for?"
Short answer: you are heading for high ground above your planned altitude, or controlled airspace at your altitude, or restricted/danger/prohibited area.
As has been said. Learn the basics first before relying on electronics.
Look at the CAA chart (paper version) of your waypoint.
