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.
5.3.1.2 Initial walking in test mode
Initial walking attempts (see fig. 35) 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. Switching processes of the electronics are also confirmed by an audible tone in parallel to controlling the
joint. INFORMATION: These settings are not saved and are intended for test purposes only!
4) Test mode is deactivated by removing the battery.

5.3.1.3 Auto-calibration
INFORMATION
Auto-calibration requires the battery to be removed and reinserted after the test mode.
The purpose of auto-calibration is to adjust the electronics to the respective gait pattern of the patient. The settings
are independent from the position of the electronics on the orthosis, the design of the orthosis and the fitting side
of the patient. We recommend installing the electronics in the vicinity of the hip and the load line (i.e. vertical to the
load) in all cases. This allows the patient to easily switch the orthosis functions from the inside of the trouser pock­
et.
5.3.1.4 Auto-calibration adjustment
The electronics need to be calibrated prior to initial use on the patient. Once the settings have been successfully
established for the patient, the calibration process does not have to be repeated. However, calibration may be
repeated at any time if the patient's gait pattern changes (see fig. 36).
Calibration process:
1) During initial use, the patient should stand between parallel bars to ensure their safety at all times.
2) The O&P professional removes the battery and reinserts it. The technician then activates calibration mode by
pushing and holding the auto-calibrate button (see Page ) until an audible tone and light signal are emitted.
3) The patient is asked to start taking a step forwards with the leg that is fitted with the orthosis (position similar to
heel strike). The patient briefly remains in this position until the technician confirms the position by pressing the
top button B (see Page ). A brief audible tone combined with a white light indicates confirmation.
4) The patient is then asked to simulate toe-off by positioning the leg behind the body's centre of gravity. Once
again, the position is confirmed by pressing the lower button C. An audible tone and light signal follow.
