The battery charger is designed for maintenance-free and
low-maintenance batteries. The charger can operate along
two characteristic curves to charge the respective battery
types. The power wheelchair is delivered with the appropri-
ate characteristic curve set in accordance with the battery
type. If the battery charger is to be used with another power
wheelchair or if new batteries are installed, the setting has
to be checked.
The battery type can be selected by means of a switch lo-
cated on the bottom of the battery charger (covered by a
green adhesive label). It is indicated by the green flashing
LED at the beginning of the charging process.
