sively on traffic, you run the risk of being involved in an accident. While driving, check
the displayed elements, change the support level, activate the sliding aid and switch the
light on or off. To change the settings, stop and enter the appropriate data.
Do not open the Comfort control unit. The Comfort control unit may be damaged if it is
opened and the warranty is void.
Do not use the Comfort control unit as a handle. If you lift the pedelec by the Comfort
control unit, you may irreparably damage the Comfort control unit.
