6. Charging the Device

The XR01 taillight is equipped with a Type-C charging port for convenient recharging.

Locate the Type-C charging port on the taillight.
Connect the provided Type-C charging cable to the taillight and a standard USB power source (e.g., computer, wall adapter).
The indicator light will show charging status (e.g., red for charging, green for fully charged).
Ensure the charging port cover is securely closed after charging to maintain its IPX6 waterproof rating.

7. Care and Maintenance

Cleaning: Wipe the taillight with a soft, damp cloth. Do not use abrasive cleaners or solvents.
Water Resistance: The device is IPX6 waterproof, meaning it is protected against high-pressure water jets. However, avoid submerging it in water for extended periods. Always ensure the charging port cover is sealed.
Storage: Store the taillight in a cool, dry place when not in use. If storing for a long time, charge the battery periodically to maintain its health.
Battery Care: Avoid completely draining the battery frequently. Charge it regularly to prolong its lifespan.

8. Troubleshooting

Problem	Possible Cause / Solution
Light does not turn on	Battery is drained: Charge the taillight using the provided Type-C cable. Device is off: Press and hold the power button to turn it on.
Auto On/Off not working	Insufficient vibration: Ensure the bike is in motion for the vibration sensor to activate. Sensor obstruction: Check if anything is blocking the sensor area.
Brake sensing not activating	Sudden deceleration required: The sensor activates on significant changes in speed. Mounting angle: Ensure the taillight is mounted securely and relatively level to detect deceleration accurately.
Water ingress	Charging port cover not sealed: Always ensure the Type-C port cover is firmly closed after charging. Damage to casing: Inspect for any cracks or damage to the housing.

9. User Tips

For optimal battery life, utilize the auto on/off feature.
Regularly check the mounting brackets for tightness, especially after riding on rough terrain.
