4.1.1 Power-on self test – initial battery installation
After all cables are connected, the battery can be inserted. The contacts have to face up and in. In order to do so,
insert the battery into the receptacle at an angle and press it against the orthosis. One can hear the battery lock
into place when it is properly inserted.
This initiates the system self-test, which runs each time the battery is inserted. Three different audible signals may
be emitted:
1) If the joint is locked when the battery is inserted, the system reports "OK" by briefly illuminating the LEDs and
with a short rising tone.
2) If the joint is open, the green and white LEDs flash accompanied by a continuous alternating tone sequence
(tone, pause, tone). Once the joint is extended, the system reports "OK" as described under 1.
3) Sensor error. Continuously illuminated (red) and continuous sound. Remove and then reinsert the battery.
4.1.2 Initial walking in test mode
Initial walking attempts (see fig. 43) should definitely be made between parallel bars or at least with the help of
crutches. In order to make the joint easy to unlock, test mode can be activated so that the system does not look for
an optimised setting but opens the joint in a defined toe-off position (provided the patient's knee joint is extended).
1) Press the T button for at least 5 seconds until the system reports that it is ready.
2) The patient takes a step forward to simulate heel strike. The technician pushes the top button B. Confirmation
is indicated by a white light and low-high tone.
3) The patient takes a step back to simulate the end of the stance phase, i.e. shortly before toe-off. The technician
confirms by pushing the bottom button C. Once again, confirmation is indicated by a white light and low-high
tone. In parallel to controlling the joint, switching processes of the electronics are also confirmed by an audible
tone. INFORMATION: These settings are not saved and are intended for test purposes only!
4) Test mode is deactivated by removing the battery.
