Maintenance

• Cleaning: Wipe the flashlight with a clean, soft cloth. Avoid using harsh chemicals or abrasive materials.
• O-rings: Regularly inspect the O-rings for wear and tear. Lubricate them with silicone grease to maintain water resistance. Replace O-rings if damaged (spare O-rings are provided).
• Threads: Keep the threads clean and lightly lubricated to ensure smooth operation and proper sealing.
• Water Resistance: The SP36 Pro is IPX8 waterproof, meaning it can be submerged up to 2 meters. Ensure all caps and covers are securely tightened before exposing to water.
• Impact Resistance: The flashlight is impact resistant up to 1 meter. While durable, avoid unnecessary drops to prolong its lifespan.

Troubleshooting

If you encounter issues with your Sofirn SP36 Pro, please refer to the following common solutions:

• Flashlight Not Turning On:
  • Ensure the insulation paper has been removed from between the battery and the body.
  • Check if the batteries are properly inserted with correct polarity.
  • Verify that the batteries are charged. Connect the flashlight to the USB-C charger.
  • Confirm the tail cap and head are screwed on tightly. Loose connections can prevent operation.
  • Check if the flashlight is in lockout mode (4 clicks from OFF to unlock).
• Flashlight Gets Warm:
  • It is normal for the flashlight to generate heat, especially on higher lumen settings (e.g., Turbo mode). This is due to the powerful LED output.
  • The Anduril UI 2 includes thermal regulation to prevent overheating. If the flashlight becomes too hot, it will automatically reduce brightness.
  • Consider using lower brightness modes for extended periods to reduce heat generation.
