1. Check for low battery: Connect the charger and observe whether the charging animation appears. If the animation appears, charge for 15-30 minutes before attempting to power on. If no animation appears, extend the charging time and check again.
2. Force Restart Procedure: If the bike computer freezes, simultaneously press and hold the two physical buttons at the bottom for 20 seconds. After hearing a "beep" sound, check whether it powers on normally.
3. After-Sales Support: If the above methods fail to resolve the issue, please contact after-sales support for assistance.
