* When the battery charge is low, first the front derailleur will stop operating, and then the rear derailleur will stop operating.
When the battery charge has been fully spent, the derailleurs will be fixed at the last gear shifting position. If the battery
indicator is illuminated red, it is recommended that you recharge the battery as soon as possible.
$ Protection function
* Rotate the front chainwheel while restoring operation after the protection function has been activated.
If the bicycle receives a strong impact, the 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 rear derailleur adjustment button on junction (A) of the SM-EW67-A-E for 5 seconds
or more. This will restore the connection between the motor and the link and clear the protection function for the rear derailleur.
If the connection is not restored, push/pull the cage sideways or move it forward and backward by hand. Operate the shifting
switches to check that the connection has been restored.
