2) While maintaining constant contact with the floor and with the leg extended, bounce on the
forefoot at 3 times or more.
3) Keep the prosthetic leg still in this position with no load.
→ A beep and vibration signal will sound to confirm that the movement pattern has been
recognised.
INFORMATION: If this beep and vibration signal does not sound, the requirements
were not observed when bouncing the foot or mute mode (silent mode) is activ
ated. For more information about mute mode, see the section "Mute mode" (see
Page 88).
4) After the beep and vibration signal sounds, keep the prosthetic leg extended and still for 1
second.
→ A confirmation signal will sound to indicate that the prosthesis has successfully switched over
to basic mode.
INFORMATION: If this confirmation signal does not sound, the leg with the prosthesis
was not correctly kept still or mute mode (silent mode) is activated. Repeat the pro
cess to correctly switch to the required mode. For more information about mute mode,
see the section "Mute mode" (see Page 88).
10 Additional operating states (modes)
10.1 Empty battery mode
Beeps and vibration signals are emitted if the available battery charge level is 5% (see Page 100).
During this time, damping settings are set to their safety mode values. This may be low or high
depending on the setting in the adjustment software. The prosthesis is then switched off. You can
switch back to basic mode (mode 1) from empty battery mode by charging the product.
10.2 Mode for charging the prosthesis
The product is non-functional during charging.
The product is set to the flexion resistance of safety mode. This may be low or high depending on
the setting configured by the prosthetist.
10.3 Safety mode
The product automatically switches to safety mode if a critical system fault occurs (e.g. failure of a
sensor signal). Safety mode remains in effect until the error has been rectified.
The switch to safety mode is indicated by beeps and vibration signals immediately prior to switch
ing (see Page 100).
Safety mode can be disabled by connecting and disconnecting the battery charger. If the product
switches into safety mode again, this means a permanent error exists. The product must be
inspected by an authorised Ottobock Service Centre.
Depending on the type and severity of the error, different remaining functionality is offered in
safety mode. This makes limited walking possible for the user depending on the type of error.
The following remaining functionality is available:
Minor error: Continuous stance phase flexion resistance is set, with the ability to initiate the
•
swing phase.
Moderate error: Continuous stance phase flexion resistance is set, with the ability to initiate
•
the swing phase. The swing phase control and stance phase extension resistance may be
available or not depending on the type of error.
•
Safety mode flexion resistance is configured. This may be low or high depending on the set
ting configured by the prosthetist.
The following functions are deactivated in safety mode:
•
OPG function
•
Stairs and obstacles function
