Notes On The Safety Modes - Otto Bock 1B1-2 Meridium Instructions For Use Manual

CAUTION
Walking down stairs
Falling due to foot being placed incorrectly on stair as a result of changed damping behaviour.
► Ensure that the patient uses the handrail when walking down stairs and places most of the sole of the foot on
the stair surface. Rolling the foot over the edge of the stair is not necessary.
► Inform the patient that particular caution is required when carrying children while walking down 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 overheating.
► 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 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.
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.

4.9 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 34) have to be observed.
CAUTION
Safety mode cannot be activated due to malfunction caused by water penetration or mechanical damage
Falling due to unexpected product behaviour because of changed damping behaviour.
► Using the product when it is defective is prohibited.
► The product must be inspected by an authorised Ottobock Service Centre.
