Advanced Temperature Regulation (ATR)
The SP35 incorporates ATR technology, which automatically adjusts the brightness level when the driver temperature reaches 55°C (131°F) to prevent overheating. This ensures stable performance and extends the lifespan of the flashlight. Once the temperature decreases, the brightness will automatically increase again.
Strømindikator
The LED indicator on the side switch provides real-time battery status:
- Solid grøn: Battery is between 50% and 100% charged.
- Fast rød: Battery is between 25% and 49% charged.
- Blinker rødt: Battery is below 25% charged and needs recharging.
Opretholdelse
- Clean the threads and O-rings regularly with a clean cloth. Lubricate them with silicone grease to maintain water resistance.
- Hvis lommelygten ikke bruges i længere tid, skal batteriet fjernes for at forhindre lækage.
- Opbevar lommelygten på et køligt, tørt sted væk fra direkte sollys og ekstreme temperaturer.
- Avoid dropping the flashlight or subjecting it to strong impacts, as this may damage internal components.

Fejlfinding
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Lommelygten tænder ikke | Battery not inserted correctly or insulating paper not removed. | Ensure battery is inserted with positive (+) end towards the head. Remove insulating paper if present. |
| Flashlight flickers or turns off unexpectedly | Low battery, loose tail cap, or dirty contacts. | Recharge the battery. Tighten the tail cap. Clean battery contacts and threads. |
| Cannot change brightness modes | Lommelygten er i låst tilstand. | Triple-click the side switch to exit lockout mode. |
| Flashlight gets hot quickly | Drift i turbotilstand i længere perioder. | This is normal due to ATR (Advanced Temperature Regulation). The flashlight will reduce brightness to prevent damage. Reduce brightness manually if desired. |
