4. Maintenance
4.1 Cleaning
Regularly clean the flashlight's body with a soft, damp cloth. Avoid using harsh chemicals or abrasive materials. Keep the threads and O-rings clean and lubricated with silicone grease to maintain water resistance.
4.2 Water Resistance
The Sofirn Q8 Plus is IPX8 rated, meaning it is protected against continuous immersion in water up to a specified depth (typically 2 meters for 30 minutes). Ensure all parts are securely tightened before exposing the flashlight to water. Do not operate the flashlight underwater for extended periods or at depths exceeding its rating.
4.3 Battery Care
To prolong battery life, avoid fully discharging the batteries. Recharge them promptly when the low battery indicator appears. If storing the flashlight for an extended period, remove the batteries or activate lockout mode to prevent parasitic drain. Store batteries in a cool, dry place.
5. Troubleshooting
- Flashlight gets hot in Turbo mode: This is normal for high-output flashlights. The Q8 Plus has thermal regulation to prevent overheating. Reduce brightness if it becomes too hot to handle.
- Light does not turn on: Ensure batteries are correctly inserted and fully charged. Check that the safety piece has been removed. Deactivate lockout mode if it is active.
- Indicator light behavior: Flashing blue to steady blue indicates charging completion. Steady orange to flashing orange indicates low battery when used as a power bank.
- Reduced brightness or runtime: Batteries may be low or nearing end of life. Recharge or replace batteries. Ensure good contact between batteries and terminals.
