Bosch Nyon BUI350 - On-Board Computer Power Supply; Using the USB Port; eBike Battery Charge Indicator

English – 13
Energy supply of the on-board computer
If the on-board computer is in the holder(4), a suffi-
ciently charged eBike battery is inserted into the
eBike and the eBike system is switched on, then the
on-board computer battery is powered and charged
by the eBike battery.
If the on-board computer is removed from the
holder(4), the power is supplied by the on-board
computer battery. If the on-board computer battery's
charge is running low, a warning message appears on
the display.
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 sys-
tem will automatically switch off after 10 minutes if it
is not activated. If this happens, the on-board com-
puter battery will also stop charging.
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 included 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 com-
puter battery, it should be recharged for one hour ev-
ery three months.
USB Port
The on-board computer can be charged via the USB
port.
To do so, open the protective cap(2) on the USB
port(8) of the on-board computer. Use the Micro A–
Micro B USB charging cable (available from your
Bosch eBike dealer) to connect the USB port of the
external device to the USB port(8) of the on-board
computer.
Following use, the USB port must be carefully re-
sealed with the protective cap(2).
A USB connection is not a watertight plug connec-
tion. 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.
Battery Charge Indicator
The battery charge indicator of the eBike batteryg
(see "<Ride Screen>", pageEnglish – 18) can be
read in the status bar. The eBike battery's state of
charge is also indicated by the LEDs on the eBike bat-
tery itself.
Color of the indicator Meaning
White The eBike battery is over
30% charged.
Yellow The eBike battery is
charged between 15%
and 30%.
Red The eBike battery is
charged between 0% and
15%.

the drive has been used
up, and assistance is
switched off. The remain-
ing capacity will be pro-
vided for the bike lights
and the on-board com-
puter.
If the eBike battery is being charged on the bike, a
corresponding notification will be displayed.
If the on-board computer is removed from the
holder(4), the state of charge that was last displayed
for the battery is saved.
