5. Întreținere
Proper maintenance ensures the longevity and optimal performance of your Sofirn C8L flashlight.
- curatenie: Wipe the flashlight body with a clean, soft cloth. For stubborn dirt, use a slightly damp pânză. Evitați curățarea abrazivă.
- Lubrifiere: Aplicați periodic vaselină siliconică pe inelele O și filetul șuruburilor pentru a menține rezistența la apă și funcționarea netedă.
- Îngrijirea bateriei: Recharge the battery regularly, especially if the flashlight will not be used for an extended period. Store the flashlight with a partially charged battery (around 50%) if storing for several months.
- Rezistenta la apa: The C8L is rated IPX8 water resistant, meaning it can be submerged up to 2 meters. Ensure all seals (like the USB-C port cover and tail cap) are properly closed and tightened before exposing to water. This rating is for incidental submersion, not for diving.
- Durabilitate: Constructed from aerospace-grade aluminum, the C8L is designed to resist scratches, abrasion, and corrosion. Avoid dropping the flashlight from significant heights or subjecting it to extreme impacts.

6. Depanare
If you encounter issues with your Sofirn C8L flashlight, please refer to the following common problems and solutions:
- Lanterna nu se aprinde:
- Ensure the battery is correctly inserted with the positive (+) terminal facing the head.
- Verificați dacă bateria este încărcată. Reîncărcați-o dacă este necesar.
- Tighten the tail cap and head assembly securely. A loose connection can prevent operation.
- Clean the battery contacts and flashlight contacts with a clean cloth.
- Lumina este slabă sau pâlpâie:
- Bateria poate fi descărcată. Reîncărcați bateria.
- Ensure the battery is fully inserted and contacts are clean.
- Check for any debris in the head or tail cap threads.
- Lanterna se încălzește în timpul utilizării:
- High brightness modes (especially Turbo) generate significant heat. This is normal. The C8L features Advanced Temperature Regulation (ATR) technology to automatically adjust output to prevent overheating.
- If the flashlight becomes uncomfortably hot, reduce the brightness level.
- USB-C charging not working:
- Ensure the USB-C cable is fully inserted into both the flashlight and the power source.
- Încercați un alt cablu USB-C sau un adaptor de alimentare.
- Verificați dacă portul de încărcare nu prezintă resturi.
