spective error code is indicated in text indicator d.
To return to the standard indicator, press any button on the

Depending on the type of error, the drive unit is automati-
cally shut off, if required. Continued travel without assis-
tance from the drive unit is possible at any time. However,
have the eBike checked before attempting new trips.
Troubleshooting actions may be performed by the
