About the RD Protection function
* Rotate the front chainwheel while restoring operation after the RD Protection function has
been activated.
If the bicycle receives a strong impact, the RD Protection function operates and the connection
between the motor and the link is momentarily severed so that the rear derailleur will no longer
operate. This is done in order to protect the system at times such as if the bicycle falls over. If this
happens, press the button on junction (A) for 5 seconds or more. This will restore the connection
between the motor and the link and clear the RD Protection function for the rear derailleur. If
recovery cannot be performed through button operation, manual operation is also possible.
Consult with a distributor in advance.

Battery indicator
* When the battery charge is low, fi rst the front derailleur will stop operating, and then the rear
derailleur will stop operating. When the battery is fully spent, the derailleurs will stop at the
positions where they were last shifted to. If the battery indicator is illuminated red, it is
recommended that you recharge the battery as soon as possible.
