7.4 Safety Mode/Empty Battery Mode

7.4.1 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 circuit 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 Damp­
ing') 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 53).

7.4.2 Empty Battery Mode

CAUTION
Danger when empty battery mode is activated
Depending on the settings established by the CPO, the orthosis either selects "high flexion
damping" (high safety/reduced comfort) or "low damping" (less safety/higher activity) when
empty battery mode is activated.
In certain situations, this can lead to falling caused by:
► Altered damping behaviour of the orthosis.
→ The CPO has to inform the user of the selected damping behaviour in empty battery mode.
