INFORMATION
If 4 short beep signals are emitted after the switching process, this means switching could not be completed. The
most frequent cause of this is that the weight was not taken off the orthosis after the first beep signal.

8.5 Safety Mode/Empty Battery Mode

8.5.1 Safety Mode

CAUTION
Safety mode cannot be activated
This may lead to falling caused by:
► Altered damping behaviour of the orthosis because of failure to activate safety mode (e.g. in case of short cir­
cuit due to water penetration).
→ Visit the CPO promptly.
→ If possible, actively secure the orthosis with the residual musculature upon heel strike until reaching the CPO.
CAUTION
Danger when activating safety mode.
In certain situations, this can lead to falling caused by:
► Altered damping behaviour of the orthosis (stance phase damping is active and swing phase is not triggered).
→ As soon as the audible signal is emitted, stop all activities involving the orthosis immediately.
→ After approximately 10 seconds and from a secure standing position, check to see if stance phase resistance
is active by slightly bending the knee joint repeatedly under controlled weight bearing.
CAUTION
Safety mode cannot be deactivated
If the orthosis is in safety mode, it is probably defective.
This may lead to falling caused by:
► Altered damping behaviour of the orthosis.
→ If safety mode cannot be deactivated by recharging the battery, an error has occurred.
→ Contact the CPO to have the error corrected.
→ Do not use a defective orthosis.
In addition to the 1st, 2nd, LOM and STA modes, the orthosis also has a safety mode.
The orthosis automatically switches to safety mode if a critical system error occurs.
In this mode, the orthosis sets the stance phase damping value (parameter 'STP Flexion Damping') but does not
trigger a swing phase. This allows the user to walk even though the system is not active.
The switch to safety mode is announced by audible signals immediately prior to the switch (see Page 74).
