4. Maintenance
4.1 Cleaning
To maintain optimal performance and appearance:
- Wipe the lights with a soft, damp cloth.
- Avoid using abrasive cleaners or solvents, as these can damage the casing or lenses.
- Ensure charging ports are free of dirt and debris.
4.2 Water Resistance
The Blinder 600 Front Light has an IP67 rating, meaning it is dust-tight and protected against immersion in water up to 1 meter for 30 minutes. The Blinder Plus Rear Light has an IP66 rating, protecting against powerful water jets. While highly water-resistant, avoid prolonged submersion or high-pressure washing.
4.3 Storage
When not in use for extended periods, store the lights in a cool, dry place. It is recommended to charge the lights periodically (e.g., every 3-6 months) to maintain battery health.
5. Troubleshooting
- Light not turning on: Ensure the battery is charged. Connect to a power source and check the charging indicator.
- Light not charging: Verify that the USB cable is securely connected to both the light and the power source. Try a different USB port or cable. Ensure the charging port on the light is clean.
- Light flickering or dim: This may indicate a low battery. Recharge the light.
- Mounting issues: Ensure the strap is correctly positioned and tightened. If the light is still loose, check for any obstructions or damage to the mounting mechanism.
