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 safety mode damping. This may be low or high depending on the setting in
the adjustment software.

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.
Default damping values are activated in safety mode. This makes limited walking possible for the
user even though the system is not active.
The switch to safety mode is indicated by beeps and vibration signals immediately prior to switch­
ing (see Page 81).
Safety mode can be disabled by connecting then 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.

10.4 Overheating mode

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:
• Sitting function
• Display of the battery charge level without additional equipment
• Switching to a MyMode
• Changes to the prosthesis setting

11 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).

12 Cleaning

1) Clean the product with a damp cloth (fresh water) when needed.
2) Dry the product with a lint-free cloth and allow it to air dry fully.

13 Maintenance

INFORMATION
This component was tested for three million load cycles in accordance with ISO 10328.
Depending on the activity level, this corresponds to a service life of three to five years.
