CAUTION
Entering a room or area with strong magnetic fields (e.g. magnetic resonance tomographs, 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 strong magnetic fields.
► Make sure that the patient takes off the product before entering the room or area and stores the product out
side this room or area.
► Damage to the product caused by exposure to strong magnetic fields cannot be repaired.
CAUTION
Remaining in areas outside the allowable temperature range
Falling due to malfunction or the breakage of load-bearing product components.
► Ensure that the patient is not in areas outside the permissible temperature range (see Page 39) during trial fit
ting.
4.8 Information on Use
CAUTION
Walking up stairs
Falling due to foot being placed incorrectly on stair as a result of changed damping behaviour.
► Inform the patient that the handrail always has to be used when walking up stairs, and that most of the sole of
the foot has to be set onto the stair surface.
► 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.
► Inform the patient that the handrail always has to be used when walking down stairs, and that the patient has
to roll over the edge of the step with the middle of the shoe.
► The warnings and error signals have to be observed (see Page 42).
► Notify the patient that resistance in the flexion and extension direction can change in case of warnings and
error signals.
► Particular caution is required when carrying children down the 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 when pulsating vibration signals start. They indicate the risk of overheating.
► As soon as these pulsating vibration signals begin, the activity level has to be reduced 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. In this case, the product should be
inspected by an authorised Ottobock Service Centre.
