6 Charging the battery
The following points must be observed when charging the battery:
• Use the 757L16-4 power supply / 757L43 charging adapter and 4E50* battery charger to charge the battery.
• With uninterrupted walking, the capacity of the fully charged battery is sufficient for at least 16 hours. It lasts
about 2 days with average use.
• We recommend charging the product once a day when used by the patient on a daily basis.
• For the maximum operating time with one battery charge, disconnecting the battery charger from the product
only immediately before using the product is recommended.
• The battery should be charged until the yellow LED on the battery charger turns off prior to initial use, and for
at least 4 hours. This calibrates the charge level indicator via the Cockpit app and by turning over the prosthes­
is.
If the battery charger is disconnected from the prosthesis too soon, the charge level indicator via the Cockpit
app and by turning over the prosthesis may not correspond to the actual charge level.
• The battery may discharge while the product is not being used.
