4.8 Information on Use

CAUTION
Walking up stairs
Falling due to foot placed incorrectly on stair as a result of changed damping behaviour.
► Always use the handrail when walking up stairs and place most of the area of the sole of your foot on the stair
surface.
► Particular caution is required when carrying children up stairs.
CAUTION
Walking down stairs
Falling due to foot 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 warnings/error signals (see Page 74).
► If pulsating vibration signals start (overheating mode activated), stop walking down stairs immediately and
check whether stance phase control is active.
► Particular caution is required when carrying children down stairs.
CAUTION
Overheating of the hydraulic unit due to uninterrupted, increased activity (e.g. extended walking down­
hill)
> Falling due to unexpected behaviour of the product because of switching into overheating mode.
> Burns due to touching overheated components.
► Be sure to pay attention to pulsating vibration signals. They indicate the risk of overheating.
► As soon as these pulsating vibrations begin, you have to reduce the activity level so the hydraulic unit can cool
down.
► Full activity may be resumed after the pulsating vibration signals stop.
► If the activity level is not reduced in spite of the pulsating vibration signals, this could lead to the hydraulic ele­
ment overheating and, in extreme cases, cause damage to the product. The product should be inspected by
an authorised Ottobock Service Centre.
CAUTION
Overloading due to unusual activities
> Falling due to unexpected product behaviour as the result of malfunction.
> Falling due to breakage of load-bearing components.
> Skin irritation due to defects on the hydraulic unit with leakage of liquid.
► The product was developed for everyday use and must not be used for unusual activities. These unusual activ­
ities include, for example, extreme sports (free climbing, paragliding, etc.).
► Careful handling of the product and its components not only increases their service life but, above all, ensures
the patient's personal safety!
► If the product and its components have been subjected to extreme loads (e.g. due to a fall, etc.), then the
product must be inspected for damage immediately. If necessary, forward the product to an authorised
Ottobock Service Centre.
CAUTION
Improper mode switching
Falling due to unexpected behaviour of the product because of changed damping behaviour.
► Ensure that the patient stands securely during all switching processes.
► Inform the patient that the changed damping characteristics have to be verified after switching and feedback
from the acoustic signal emitter must be observed.
► Switching back to basic mode is mandatory once the activities in MyMode have been completed.
► If required, take the weight off the product and correct the switching.
