6. Maintenance

• Cleaning: Wipe the flashlight body with a soft, damp cloth. Do not use abrasive cleaners or solvents. Keep the lens clean for optimal light output.
• Battery Replacement: When the battery is depleted and no longer holds a charge, replace it with a new, high-quality 18650 rechargeable battery following the correct polarity (+/-) procedure.
• Storage: If storing the flashlight for an extended period, remove the battery to prevent leakage and store it in a cool, dry place.
• Water Resistance: The flashlight is waterproof, but avoid prolonged submersion or use in extremely harsh wet conditions. Ensure the charging port cover is securely closed when not in use.

7. Troubleshooting

• Failure to Turn On:
  • Verify correct battery installation and ensure the insulating paper has been removed.
  • Check if the battery is charged.
• Dim Light Output:
  • May indicate low battery charge. Recharge the flashlight.
  • Ensure the lens is clean.
• Unresponsive Switch:

  • Ensure the battery is properly seated.
  • If issues persist, the battery may need replacement.
• Flashlight Gets Warm:
  • It is normal for the flashlight body to become warm after extended use, especially on high settings. This is due to heat dissipation from the LED.
