Information On Proximity To Certain Areas - Otto Bock C-Leg 3C98-3 Instructions For Use Manual

Safety
CAUTION
Operator errors during the adjustment process with the adjustment software
Falling due to unexpected behaviour of the product.
► Participation in an Ottobock product training course is mandatory prior to using the product. Additional
product training courses may become necessary to qualify for software updates.
► Correctly entering the foot size, the prosthesis dimensions and the body weight are important criteria for the
quality of the 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.
► Always enter the weight in the specified unit.
► Ensure that the required dimensions are selected and entered correctly.
► If the patient uses walking aids (e.g. crutches or walking canes) during the adjustment process, readjustment
is required as soon as the patient stops using these walking aids.
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.
CAUTION
Using the product without calibration
Falling due to unexpected product behaviour as the result of the swing phase being initiated too early/too late.
► Use the adjustment software to carry out calibration at the beginning of static alignment optimisation and at
the end of dynamic alignment optimisation.

4.7 Information on Proximity to Certain Areas

CAUTION
Distance to HF communication devices is too small (e.g. mobile phones, Bluetooth devices, WiFi
devices)
Falling due to unexpected behaviour of the product caused by interference with internal data communication.
► Therefore, keeping the following minimum distances to these HF communication devices is recommended:
• Mobile phone GSM 850/GSM 900: 0.50 m
• Mobile phone GSM 1800/GSM 1900/UMTS: 0.35 m
• DECT cordless phones incl. base station: 0.18 m
• WiFi (routers, access points,...): 0.11 m
• Bluetooth devices (third-party products not approved by Ottobock): 0.11 m
CAUTION
Proximity to sources of strong magnetic or electrical interference (e.g. theft prevention systems, metal
detectors)
Falling due to unexpected behaviour of the product caused by interference with internal data communication.
► Avoid remaining in the vicinity of visible or concealed theft prevention systems at the entrance/exit of stores,
metal detectors/body scanners for persons (e.g. in airports) or other sources of strong magnetic and electric­
al interference (e.g. high-voltage lines, transmitters, transformer stations, computer tomographs, magnetic
resonance tomographs, etc.).
If this cannot be avoided, ensure at least that you are able to walk or stand steadily (e.g. by using a handrail or
the support of another person).
► When walking through theft prevention systems, body scanners or metal detectors, watch for unexpected
changes in the damping behaviour of the product.
CAUTION
Remaining in areas outside the allowable temperature range
Falling due to malfunction or the breakage of load-bearing product components.
► Avoid remaining in areas with temperatures outside of the permissible range (see Page 76).
