Otto Bock C-Leg 3C98-3 Instructions For Use Manual page 21

If there is contact between the socket and the joint (hydraulic unit, frame) at maximum flex­
►
ion, then the joint must be fitted with a flexion stop (e.g. in the case of voluminous residual
limbs).
If contact between the socket and joint (hydraulic unit, frame) occurs anyway at maximum
flexion, the socket has to lie flat on the frame (with the help of soft padding on the socket).
CAUTION
Insufficient insertion depth of the tube adapter
Falling due to breakage of load-bearing components.
Insert the tube adapter at least 40mm to ensure operational safety.
►
The patient must be seated for length adjustments.
►
CAUTION
Operator errors when adjusting settings using the adjustment software
Falling due to unexpected prosthesis behaviour.
Do not charge the prosthesis battery during the adjustment process since the prosthesis is
►
not functional while the battery is being charged.
During the adjustment process, the prosthesis must not remain unattended when connected
►
to the adjustment software while being worn by the patient.
Observe the maximum range of the Bluetooth connection and note that obstacles may limit
►
this range.
During the data transfer (PC to prosthesis), the prosthesis wearer should sit or stand still,
►
and the BionicLink PC must not be removed from the computer.
If you want to make only temporary changes to the settings while connected to the adjust­
►
ment software, you must reverse these changes before disconnecting the adjustment soft­
ware.
You must also ensure the patient does not leave the range of the Bluetooth connection if set­
tings have been changed temporarily.
Inform the patient immediately if the data connection is accidentally interrupted during the
►
adjustment process.
The connection to the prosthesis must always be disconnected after adjustments have been
►
completed.
Successful participation in an Ottobock product training course is mandatory prior to initial
►
use. Additional product training courses may be required to qualify for software updates.
The correct input of the foot size, prosthesis dimensions, body weight and calibration are
►
important criteria for achieving a quality fitting. If the values are too high, the prosthesis may
not switch to the swing phase. If the values are too low, the prosthesis may trigger the swing
phase at the wrong time.
If the patient uses walking aids (e.g., crutches or walking canes) during the adjustment pro­
►
cess, you will need to readjust the settings when the patient no longer requires these aids.
Use the online help function integrated into the software.
►
Do not disclose your personal access data.
►
CAUTION
Safety mode flexion resistance set too low
Falling due to unexpected product behaviour as the result of switching into safety mode.
Safety mode flexion resistance should be configured so that it is possible to stand safely
►
without the knee joint buckling.
