8. Further information
Cleaning: Protect your headlight against exposure to water under high pressure.
For example, never point a water hose or high-pressure cleaner directly at the headlight.
Transport: If you transport your bike on your car in the rain, cover the headlight, with a plastic bag, for
example, to prevent moisture penetration.
Radio speedometers: The electronics of radio speedometers and LED headlights may interfere with
each other. Interference can be reduced by maximising the distance between the LED headlight and
the radio speedometer and minimising the distance between the transmitter and receiver of the radio
speedometer.
Disposal: Electronic components must not be handled as household waste but are to be disposed of as
hazardous waste.
Repairs: In case of defects, please contact your specialist bicycle dealer or our service department at
service@bumm.de oder +492354 915-7111.
