power to reset.

„ Connection and communication with PC

and an E-TUBE PROJECT can be used to carry out tasks such as customizing single

If your versions of E-TUBE PROJECT software and firmware for each component are not
up to date there could be problems operating the bicycle. Check the software version
and update it to the latest one.
