The rechargeable battery charge level of the
electronic gearshift is also visible on the dis-
play. When the charge state is low (thus when
only one rechargeable battery bar is shown),
the rechargeable battery must be recharged.

removed as follows: the flap on the side is
opened and the push button is pressed-in (fig-
ure 28). Now the rechargeable battery can be
pulled out along the retaining rail and charged
using the charger included in the scope of
supply. During the charging procedure, an
