4.1 LED control panel
The control panel on the handlebar has
EN
three or four buttons (depending on the
model) and two rows of LED indicators.
The Power button (on/off) is located on
the right hand side at the bottom. Press
this button to switch the control panel on
and off. After it has been switched on, the
system is always in the medium power-
assist mode "Sport".
The buttons used to control the level of
assistance are located on the left-hand
side of the control panel.
Above and to the right you can see the
row of LED indicators that shows which
level of assistance has been activated and
the current battery charge state.
If the model features pushing assistance,
the switch for this will be on the under-
side of the control panel.

4.2 Troubleshooting
The control panel will alert you if prob-
lems arise. In such a situation, the LEDs
on the battery display will show a particu-
lar flash pattern:
• If all of the LEDs on the battery display
flash simultaneously immediately after
switching the system on, this means
that there is a problem with the battery
communication.
In that case, switch the system off and
then back on again. If the problem oc-
curs again, put the battery in the charger,
so that the battery management can
eliminate an existing problem. You can
also use another approved battery. If the
flashing signal persists, have the system
checked by a specialist dealer.
