Steps to take in the event of a failure
If the rear light is defected, it must be immediately replaced.
If you ride with the seat post low, it may be the case that the seat clamp covers one of the lenses. Please ensure that the clamp area is not directly tightened on to the lens as per the illustration below.
When fitting the saddle, please make sure that the small transparent rubber cap for the microUSB connection is clamped under the strut.
Do not pull on the charging cable excessively.
If the USB connector is exposed to heat, it may lose its shape.
We recommend using the supplied USB cable to ensure proper battery charging.
If the USB plug has deformed, it must be replaced.
