light button (3).
If the light is switched on, a symbol is displayed in the status
bar of the display.
Switching the bike lights on and off has no effect on the
backlighting of the display.

Powering external devices via the USB port
The USB port can be used to operate or charge most devices
that can be powered via USB (e.g. various mobile phones).
Charging requires the on-board computer to be mounted
and a sufficiently charged battery to be inserted in the eBike.
Open the protective cover (17) for the USB port on the on-
board computer. Use a Micro-A – Micro-B USB charging
cable (available from your Bosch eBike dealer) to connect
the USB port on the external device to the USB port (6) on
the on-board computer.
Once the electrical load has been disconnected, the USB
port must be carefully resealed with the protective cover
(17).
USB connections are not waterproof. When cycling in
u
the rain, do not connect any external devices and
make sure that the USB port is fully sealed by the pro-
tective cover (17).
Important: If electrical loads are connected, this can affect
the range of the eBike.
Error code display
The eBike system's components are continuously and auto-
matically monitored. If an error is detected, the correspond-
ing error code is displayed on the on-board computer.
The drive may be automatically shut down, depending on the
type of error. However, if you wish to continue cycling, you
will always be able to do so without assistance from the
drive. Before undertaking any other journeys, the eBike
should be checked.
Have all repairs performed only by an authorised bike
u
dealer.
