7. At the top of the stairs hold the prosthesis on the ground for approx. 3 seconds to interrupt the stair ascent
function and avoid unwanted behaviour.
Always use the bannister or handrail when ascending or descending ramps and stairs.
WARNINGS & ERRORS
The prosthetic knee behaves abnormally
–
Action:
Stop walking and determine whether stance support is present.
–
Cause:
Steps are not properly detected.
–
Solution:
Hold the prosthetic foot in contact with the ground for approx. 3 seconds then resume your
current activity. If the problem persists, reset the prosthesis by powering it off then on again and check if it
returns to normal operation. If it does not, refrain from using the prosthesis and contact your Össur
representative.
The prosthesis vibrates/beeps and the LED flashes orange slowly
–
Cause 1:
“Low-battery warning”
: the battery is nearly depleted (battery charge reaches about 10%), leaving
you approx. 10 min of walking autonomy.
–
Solution:
Check the battery status to confirm if this is the cause of the problem. If it is, only the bottom LED
will go on when you press the battery status button. Replace the battery by a spare, fully charged.
–
Cause 2:
“Overheat warning”
: the prosthesis temperature is increasing.
–
Solution:
Stop your current activity, feel the prosthesis temperature with your hand to confirm if this is the
cause of the problem and let the prosthesis cool before resuming your current activity.
The risk of an
“overheat warning”
may increase due to high ambient temperature, especially if you are
performing an
“energy demanding”
activity like ascending stairs or standing up.
The prosthesis vibrates/beeps repeatedly and the LED flashes orange quickly
–
Action:
Stop walking and determine whether stance support is present.
The prosthesis motor will shut down soon, meaning that the prosthetic knee will no longer be functional
and will provide limited support.
–
Cause 1:
“Low-battery error”
: the battery charge has dropped below a critical level.
–
Solution:
Check the battery status to confirm if this is the cause of the problem. If it is, only the bottom LED
will go on when you press the battery status button. Replace the battery by a spare, fully charged.
–
Cause 2:
“Overheat error”
: the prosthesis temperature has reached a critical level.
–
Solution:
Stop your current activity and feel the prosthesis temperature with your hand to confirm if this is
the cause of the problem. Let the prosthesis cool. Reset the prosthesis by powering it off then on again and
check if it returns to normal operation. If it does not, refrain from using the prosthesis and contact your
Össur representative.
