9.3 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 85).
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 which enables limited walking by the user.
The following remaining functionality is available:
•
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
•
Stance function
•
Sitting function
9.4 Overheating mode
INFORMATION
When mute mode (silent mode) is activated, no beep and vibration signals are generated.
When the hydraulic unit overheats due to uninterrupted, increased activity (e.g. extended walking
downhill), damping is increased along with the rising temperature in order to counteract the over
heating. When the hydraulic unit cools down, the product switches back to the damping settings
that existed before the overheating mode.
Overheating mode is not activated in the MyModes.
Overheating mode is indicated by a long vibration every 5 seconds.
The following functions are deactivated in overheating mode:
•
OPG function
•
Stairs and obstacles function
•
Stance function
•
Sitting function
•
Display of the battery charge level without additional equipment
•
Switching to a MyMode
10 Storage and bleeding
Air may accumulate in the hydraulic unit if the product is stored for longer periods and not in an
upright position. This is noticeable through sounds and irregular damping behaviour.
The automatic bleeding mechanism ensures that all functions of the product are again intact after
approximately 10 - 20 steps.
Storage
•
When storing the knee joint, press the top of the knee to the flexion stop.
•
Avoid extended disuse of the product (use the product regularly).
