► CAUTION! Since there is a risk of falling when the switching threshold is not adjusted cor­
rectly, allow the patient to walk only with safeguards in place.

cannot be enabled.
INFORMATION: The purpose of this setting and the subsequent decrease of the switching
threshold is to prevent the stance phase flexion resistance from being deactivated too soon or
not at all, and for the patient to gain confidence in the function.
► Subsequently, decrease the switching threshold in especially small increments (max. 15°)
until the swing phase can be initiated. Do not further reduce the switching threshold value
after the appropriate setting is found.
► Adjust the settings first at normal walking speed, then with short, quick steps and finally with
long, fast steps.

heel strike. After making adjustments (
test the settings while walking with support (e.g. between parallel bars) at different walking
speeds, because the switching threshold may have been changed so that stance phase flex­
ion resistance is deactivated under heel load. In this case, increase the switching threshold
setting clockwise correspondingly.
