11 Additional operating states (modes)

11.1 Empty battery mode

Beeps and vibration signals are emitted if the available battery charge level is less than 5% (see Page 91). 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.

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 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 switching (see Page 91).
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.

11.4 Overheating mode

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 indicated by a brief vibration every 5 seconds.

12 Cleaning

1) Clean the product with a damp cloth and mild soap (e.g. Ottobock 453H10=1 Derma Clean) when needed.
Ensure that no liquid penetrates into the system component(s).
2) Dry the product with a lint-free cloth and allow it to air dry fully.

13 Maintenance

Depending on the activity level, this corresponds to a service life of three to five years.
The duration of use can be individually extended depending on the intensity of use by performing regular service
inspections.
Regular service inspections are recommended in the interest of the patient's safety and in order to maintain operat­
ing reliability and protect the warranty. These service inspections include an inspection of sensors and replacement
of worn parts.
