Avoid remaining in the vicinity of visible or concealed theft prevention systems at the
►
entrance/exit of stores, metal detectors/body scanners for people (e.g. in airports) or other
sources of strong magnetic and electrical interference (e.g. high-voltage lines, transmitters,
transformer stations...).
If this cannot be avoided, make sure to at least have a safeguard when walking or standing
(e.g. 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.
In general, monitor the product for unexpected changes in the damping behaviour when
►
electronic or magnetic devices are in the immediate vicinity.
CAUTION
Entering a room or area with strong magnetic fields (e.g. magnetic resonance tomo
graphs, MRT (MRI) equipment...)
>
Falling due to unexpected restriction of the product's range of motion caused by metallic
objects adhering to the magnetised components.
>
Irreparable damage to the product due to the effect of a strong magnetic field.
Take off the product before entering a room or area with strong magnetic fields and store the
►
product outside this room or area.
Damage to the product caused by exposure to a strong magnetic field cannot be repaired.
►
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 84).

4.7 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 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 warnings/error signals (see page 88).
►
Be aware that resistance in the flexion and extension direction can change in case of warn
►
ings and error signals.
Particular caution is required when carrying children down stairs.
►
CAUTION
Overheating of the hydraulic unit due to uninterrupted, increased activity (e.g. extended
walking downhill)
>
Falling due to unexpected behaviour of the product because of switching into overheating
mode.
