6. Fejlfinding
If you encounter issues with your ThruNite TN12 Pro, please refer to the following common solutions:
- Lommelygten tænder ikke:
- Ensure the battery is correctly inserted with the positive (+) terminal facing the head.
- Kontroller om batteriet er opladet. Genoplad om nødvendigt.

- If it becomes uncomfortably hot, switch to a lower mode.
- Opladning virker ikke:
- Sørg for, at USB-C-kablet er korrekt tilsluttet både lommelygten og strømkilden.
