5. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Slow GPS acquisition | Initial connection, poor satellite signal, outdated course data. | Ensure you are in an open area with a clear view of the sky. Allow 3-5 minutes for initial connection. Update course data regularly. |
| Watch freezes or loses connectivity | Software glitch, low battery, temporary signal loss. | Restart the watch. Ensure the battery is sufficiently charged. If issues persist, perform a firmware update via the CANMORE website. |
| Course not loading or incorrect yardage | Outdated course data, weak satellite connection. | Verify that your course data is up to date. Ensure a strong GPS signal. Try restarting Golf Mode. |
| Battery drains quickly | Frequent GPS usage, old battery. | Ensure the watch is fully charged before use. GPS mode consumes more power; standby mode offers longer battery life. |
