NOTICE
Risk of damage to the battery charger / risk of damage caused by the battery charger. Please
note the following when using the charger:
• Only use a battery charger supplied by Otto Bock which has been tested and approved by Otto
Bock for the respective batteries (observe information on the charger). Failure to do so can result in
a battery explosion and possible impairment of health due to contact with battery acid.
• The information on the nameplate of the charger must match the country-specific voltage of the re-
spective power supply network.
• Only use the battery charger within the specified ranges of temperature and humidity.
• Place the rubber feet of the battery charger on a level surface.
• When setting the charger up close to a window, protect it against direct sunlight.
• Keep the charger from overheating. The vent openings on the back of the charger must not be covered.
• Turn off the control unit during the charging process so that the entire charging current flows to the
battery.
• Avoid dust and dirt. Only clean with a dry cloth.
The remaining battery capacity determines the range of the power wheelchair. The following
factors affect the battery capacity:
❒ Ambient temperature
❒ Age of the batteries
❒ Amount of use
❒ Charging process
Driving for an extended period of time in the lower range of the battery indicator will result in deep
discharge and therefore battery damage. The control unit of the power wheelchair switches to
power-saving creep speed when driving once the battery capacity is low.
