- Threads: Keep the threads of the tail cap clean and lightly lubricated to ensure smooth operation and good electrical contact.
- Storage: If storing the flashlight for an extended period, remove the battery to prevent leakage and damage. Store in a cool, dry place.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Flashlight does not turn on. | Low or depleted battery. Incorrect battery installation. Loose tail cap. | Recharge or replace battery. Ensure battery is inserted correctly (positive end towards head). Tighten tail cap. |
| Light output is dim or flickers. | Low battery. Poor electrical contact. | Recharge battery. Clean battery contacts and threads. Ensure tail cap is tight. |
| Flashlight gets hot during use. | High brightness modes generate heat. | This is normal for high-output flashlights. The SF-R26 has a heat sink design. If it becomes excessively hot, switch to a lower mode. |
| USB charging not working. | USB cable faulty. Power source issue. Battery not installed. | Try a different USB cable or power source. Ensure battery is correctly installed. |
