Okay. Set the base up on known point. Go through base/rover setup. Everything looks good on base/rover screen (no red showing, 2d delta fine). Disconnect blue tooth. Action screen, hit GNSS. The dreaded CDF shows up. Reboot Ls+ and go to action screen after reboot hit GNSS. All is fine, Green and engine numbers showing. Ready to use and no problems. Using LS+ and T-3 setup. Seems to be a constant thing on setup. Any Ideas would be appreciated. Mike
