The term eBike battery is used in these instructions to

from the system generation the smart system.
Read and observe the safety warnings and instruc-
u
tions contained in all the operating instructions for
the eBike components and in the operating instruc-
tions of your eBike.
Do not attempt to secure the on-board computer or
u
operating unit while riding!
Do not allow yourself to be distracted by the on-board
u
computer's display, particularly by text overlays
shown according to the situation. The display of riding
information does not absolve the rider of the need to ex-
ercise due caution. If you do not focus exclusively on the
traffic, you risk being involved in an accident. If you want
to make entries in your on-board computer other than
switching the riding mode, stop cycling and enter the rel-
evant details.
Do not use your smartphone while riding. If you do not
u
focus exclusively on the traffic, you risk being involved in
an accident. Only enter the relevant data having stopped
first.
Set the on-board computer brightness so that you can
u
adequately see important information such as speed
and warning symbols. Incorrectly set brightness on the
on-board computer may lead to dangerous situations.
Do not open the on-board computer. Opening the on-
u
board computer may damage it beyond repair and void
any warranty claims.
Do not use the on-board computer as a handle. Lifting
u
the eBike up by the on-board computer can cause irrepar-
able damage to the on-board computer.
Do not stand your eBike upside down on its saddle and
u
handlebars if the on-board computer or its holder pro-
trude from the handlebars. This may irreparably dam-
age the on-board computer or the holder. Also remove
the on-board computer before placing the eBike on a wall
mount to ensure that the on-board computer does not fall
off or become damaged.
The on-board computer Purion 400 contains a buzzer.
u
Loud signal tones may sound under certain circum-
stances. The loud sound can damage hearing. It is
therefore advisable to keep a sufficient distance from the
on-board computer.
