Troubleshooting
- Device not powering on:
- Ensure the device is fully charged. Press and hold the left button for several seconds until it powers on. If it still doesn't turn on, try charging it for a longer period.
- No GPS signal/inaccurate readings:
- Ensure you are in an open outdoor area with a clear view of the sky. The GPS symbol should be steady, not blinking. If issues persist, try restarting the device. For greater precision or in areas with poor GPS signal, consider connecting an external speed sensor.
- Cannot connect to OnelapFit App:
- Ensure Bluetooth is enabled on your smartphone and the CC400. Make sure the app is updated to the latest version. Try restarting both the device and your phone. If pairing fails, try unpairing and re-pairing the device in the app's settings.
- Data not synchronizing to Strava/TrainingPeaks:
- Verify that your Strava and TrainingPeaks accounts are correctly linked within the OnelapFit App. Ensure you have an active internet connection on your smartphone when attempting to synchronize data.
