To charge the on-board computer battery, put the on-board computer back
in the holder
(4) . Note that if you are not charging the eBike battery, the
eBike system will automatically switch off after 10 minutes if it is not acti-
vated. If this happens, the on-board computer battery will also stop charg-
ing.
You can also charge the on-board computer via the USB port
(8) . To do this,
open the protective cap (2) . Use a Micro USB cable to connect the USB port
on the on-board computer to a commercially available USB charger (not in-
cluded with the product as standard) or to the USB port of a computer (max.
5 V charging voltage; max. 1500 mA charging current).
If the on-board computer battery is not recharged, the date and time will be
retained for approx. six months.
Note: To maximize the lifespan of the on-board computer battery, it should
be recharged for one hour every three months.
Following use, the USB port must be carefully resealed with the protective
cap
(2) .
A USB connection is not a watertight plug connection. When cycling in
wet conditions, ensure no external devices are connected and that the
USB port is fully covered by the protective cap
(2).
It is not possible to charge external devices via the USB port.
