Operation
For an optimal charging frequency the following applies:
n
The batteries can be charged at any time, regardless of
the remaining charge.
n
It takes about 10 hours until a discharged battery (lowest
segment in the battery symbol is ashing) is completely
charged. Subsequently, the power wheelchair can remain
connected to the charger without causing any problems;
the charger has a programmed recharge phase which
ensures that maximum battery capacity is maintained.
n
For daily use, it is recommended to connect the charger
overnight so that the full capacity is available every day.
n
When the power wheelchair is not used for an extended
period of time, the battery will become discharged over
time. It is therefore necessary to charge the battery at
least once a week to maintain full battery capacity. We
also recommend removing the fuse when the power wheel-
chair is not going to be used for an extended period of
time.
nTotal discharge of the batteries should be avoided.
n
When the batteries are charging, the controls on the
power wheelchair must be switched off to allow the charg-
ing current to be fed completely into the battery.
The following must be observed when charging the batteries:
n
Only the battery charger provided by Otto Bock may be
used for charging. Failure to comply with this requirement
will render the warranty null and void.
n
The voltage settings on the battery charger must corre-
spond to the voltage used in your country.
