► Extending the knee joint and placing load on the toes may cause the product to switch to the
swing phase (no damping).
Always take the first step from a standing position with the contralateral leg.
►
CAUTION
Risk of falling when walking backwards
Falling due to unexpected product behaviour because of changed damping behaviour.
► Extending the knee joint and placing load on the toes may cause the product to switch to the
swing phase (no damping).
► When walking backwards, take smaller steps and put a consistent load on the foot in order
to prevent unintentional buckling due to switching to the swing phase.
CAUTION
Walking up stairs
Falling due to foot being placed incorrectly on stair as a result of changed damping behaviour.
► Always use the handrail when walking up stairs and place most of the sole of your foot on
the stair surface.
► Always step down with the contralateral leg, followed by the leg with the product. Support
from the spring element while walking up stairs (bouncing with the product extended) is not
allowable and must be avoided. This type of load can cause the product to switch to the
swing phase (no damping).
Particular caution is required when carrying children up the stairs.
►
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 roll over the edge of the step with the
middle of the shoe.
► Observe the warning/error signals (see Page 65).
► If the audible alarm sounds, stop walking down stairs immediately and check whether
stance phase control is active.
► Particular caution is required when carrying children down stairs.
CAUTION
Walking down stairs and ramps
Falling due to unexpected, high stance phase damping during the transition from a level surface
to stairs or ramps.
► Pay attention to the changed product behaviour.
► Verify changed stance phase damping before walking on stairs or ramps.
CAUTION
Overheating of the hydraulic unit due to uninterrupted, increased activity (e.g. extended
walking downhill)
> Falling due to product malfunction caused by overheating of the hydraulic unit
> Hydraulic unit defects with associated leakage of liquid.
> Burns due to touching overheated components
Observe the recurring beep signals emitted by the product. They indicate the risk of over­
►
heating.
