Additional operating states (modes)
→ 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 cor
rectly kept still or mute mode (silent mode) is activated. Repeat the process to correctly switch to the
required mode. For more information about mute mode, see the section "Mute mode" (see Page 96).
11 Additional operating states (modes)
11.1 Empty battery mode
Beeps and vibration signals are emitted if the available battery charge level is 5% (see Page 107). 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.
11.2 Mode for charging the prosthesis
The product is non-functional during charging.
The product is set to safety mode damping. This may be low or high depending on the setting in the adjustment
software.
11.3 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 switching (see
Page 107).
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 functionality is available:
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.
Severe error: Safety mode flexion resistance is configured. This may be low or high depending on the setting
•
in the adjustment software. Depending on the type of error, the product may also be blocked entirely in the flex
ion direction.
The following functions are deactivated in safety mode:
•
OPG function
•
Stairs and obstacles function
•
Stance function
•
Sitting function
11.4 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), damp
ing is increased along with the rising temperature in order to counteract the overheating. 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:
•
Sitting function
•
Display of the battery charge level without additional equipment
•
Switching to a MyMode
