Charging the knee joint
INFORMATION
Charging the knee completely before use is strongly recommended�
INFORMATION
Charging the battery is only possible at temperatures over 0 °C�
Fully charging the battery in the knee joint takes approx� 6 - 8 hours� The better the connection
between the charger and receiver on the knee joint (not interrupted e�g� by a sock), the shorter
the charging time�
CAUTION
Charging the prosthesis without taking it off. During charging of the prosthesis the damp-
ing characteristics of the knee joint change because the adjustable safety mode is activated� In
certain situations, this can cause the user to fall� For safety reasons, take the prosthesis off before
charging the battery�
1
Connect the power cord to the charger with the correct polarity (Figure 1)�
1� Start the inductive charging process by connecting the charger to the receiver on the back of the
knee joint� The charger is held in place by a magnet (Figure 2a / 2b)� Verify the battery capacity
using the LEDs on the side (Figure 3) and the charging process based on the colour of the illu-
minated ring (Figure 2b) (see tables below)�
2� End the inductive charging process by disconnecting the charger from the receiver� The knee
joint performs a self-test and is then ready for operation, provided it is connected to the AXON
Tube Adapter� This is indicated by a single vibration signal and beep� If this is not the case, an
error has occurred� In that case please send the knee joint to your prosthetist or an authorised
Ottobock Service Centre�
INFORMATION
After disconnecting the charger the knee joint will conduct a self test� Be sure not to move the
knee joint during this brief self test, since it can cause an error� If you encounter this error, the
problem can be corrected by reconnecting and then disconnecting the charger�
INFORMATION
Charging is not possible if the distance between the transmitter and receiver is greater than 2
mm� However, charging should proceed normally if, for example, a sock or Superskin between
transmitter and receiver of the charger (also see the Charging Process table)�
