Unhappy How to calibrate Speed sensor with Garmin GNX 20

Hi!
I purchased a Garmin GNX20 with a Airmar DST800 paddlewheel speed sensor. I noticed that the boatspeed value is always 0.5/0.8 higher than the SOG (from my GPS).

When I tried to calibrate it, the menu says "bring the boat to cruising speed, note down, stop and press ok". What I do is:
1) set the engine to work at 1500 rpm, so the gnx20 displays boatspeed 4.5 kts (sog 4kts)
2) I stop the boat
3) I press ok --> 4,5 value appears on screen
4) press ok --> "calibration error" appears on screen.

What am I doing wrong? Thxs.
