10 Additional operating states (modes)

10.1 Empty battery mode

Beeps and vibration signals are emitted if the available battery charge level is less than 5% (see
Page 89). During this time, damping settings are set to their safety mode values. 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 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 error occurs (e.g. failure of
a sensor signal) or when the battery is empty. 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 89).
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 indicated by a brief vibration every 5 seconds.
