8. Fehlerbehebung
If you encounter issues with your ROCKBROS Bike Handlebar End Plugs Light, refer to the following common solutions:
- Licht geht nicht an: Stellen Sie sicher, dass der Akku geladen ist. Halten Sie den Ein-/Ausschalter 2 Sekunden lang gedrückt.
- Lights not syncing: Ensure both lights are powered on. Double-tap the button on one light to initiate sync mode. Make sure they are within close proximity.
- Kurze Akkulaufzeit: Ensure the lights are fully charged. Check if they are accidentally left on in a mode with higher power consumption. Verify the intelligent sensing is functioning correctly to prevent unnecessary power drain.
- Licht fällt vom Lenker: Re-check the installation steps. Ensure the light is twisted to expand and fit snugly, and any securing screws are tightened. Consider adding a small amount of friction tape inside the handlebar if the fit is still loose.
- Bremssensorik funktioniert nicht: Ensure the light is firmly mounted and not loose, as movement can interfere with the sensor.
