1. You have a Gen-1 sensor actively paired. 
2. Your Arccos Caddie Link did not receive a GPS lock prior to starting your round. Please make sure you give Arccos Caddie Link enough time to acquire a strong GPS signal by turning your Arccos Caddie Link Pro on at least 5 minutes prior to your round. In order to receive a strong GPS signal, please make sure the Arccos Caddie Link has a clear view of the sky. 
3. Lastly you should check your current time and date settings. If you go to Settings -> General -> Date and Time you should have "Set Automatically" toggled ON.

If you continue to have difficulty with your Arccos Link, please contact Starter@arccosgolf.com or Submit a Request and share what troubleshooting has been attempted.
