6. Maintenance
To ensure the longevity and optimal performance of your AXA Riff LED Taillight, follow these maintenance guidelines:
- Cleaning: Wipe the light housing with a soft, damp cloth. Do not use abrasive cleaners or solvents, as they may damage the plastic material.
- Battery Replacement: When the light dims or stops functioning, replace the batteries. Open the battery compartment, remove old batteries, and insert new ones, observing correct polarity.
- Water Resistance: The taillight is water-resistant (IPX6 rated), meaning it can withstand strong jets of water. However, it is not designed for submersion. Ensure the battery compartment cover is securely closed to maintain water resistance.
