Notes On The Safety Modes - Ottobock 1B1-2 Gebrauchsanweisung

CAUTION
Walking down stairs
Falling due to foot being placed incorrectly on stair as a result of changed damping behaviour.
► Always use the handrail when walking down stairs and place most of the sole of your foot on
the stair surface. Rolling the foot over the edge of the stair is not necessary.
► Particular caution is required when carrying children down the stairs.
CAUTION
High temperature of the hydraulic unit due to uninterrupted, increased activity (e.g.
extended walking downhill)
Falling due to unexpected behaviour of the product caused by use in overheating mode.
► Be sure to pay attention when pulsating vibration signals start. They indicate the risk of over­
heating.
► As soon as these pulsating vibration signals begin, you must reduce your level of activity so
the hydraulic unit can cool down.
► Please note that the range of motion in the ankle joint is reduced as the temperature
increases, and this may ultimately result in the ankle joint being locked completely. Special
caution is therefore required, especially when walking down stairs.
► Full activity may be resumed after the pulsating vibration signals stop.
CAUTION
Improper mode switching
Falling due to unexpected behaviour of the product because of changed damping behaviour.
► Ensure that you stand securely during all switching processes.
► Verify the changed damping characteristics after switching and observe the feedback from
the acoustic signal emitter.
► Switch back to basic mode once the activities in MyMode have been completed.
► Take the weight off the product and correct the switching, if required.
CAUTION
Using prosthetic foot without footshell
Falling due to slipping when walking on smooth floor surfaces (tiles).
► Do not use the prosthetic foot without the accompanying footshell.
CAUTION
Using prosthetic foot with a damaged foot shell
> Falling due to unexpected product behaviour as the result of malfunction.
> Falling due to breakage of load-bearing components.
► Do not use the prosthetic foot when the foot shell is damaged. Replace damaged foot shells
immediately, before using the product again.

4.8 Notes on the safety modes

CAUTION
Using the product in safety mode
Falling due to unexpected product behaviour because of changed damping behaviour.
► The warnings/error signals (see Page 79) have to be observed.
