When starting your SpotOn GPS system for the first time each day, sometimes you will encounter an error where the GPS is attempting to locate satellites.
If you are outside and this error persists for more than a few minutes, move around your yard for a short while. The collar has built-in motion detection to help save battery if your dog is not moving, and that can cause the collar to not read incoming GPS signals. By moving around, it will refresh those motion detectors and you should shortly receive a GPS signal.
