Troubleshooting
If you encounter issues with your Fi Series 3+ collar, consider the following:
- No GPS Signal: Ensure your dog is in an area with good cellular coverage (AT&T network). GPS accuracy can be affected by dense foliage, buildings, or remote rural areas.
- Battery Draining Quickly: Check the app for frequent 'Lost Dog Mode' activations or prolonged periods outside of a Wi-Fi-connected Safe Zone, as these consume more battery. Ensure the device is fully charged regularly.
- App Not Updating: Verify your smartphone has an active internet connection and that the Fi app is updated to the latest version.
- Collar Not Connecting: Ensure the device is charged and within Bluetooth range of your phone or a Wi-Fi-connected charging base.
