Additional Operating States (Modes); Empty Battery Mode; Mode For Charging The Prosthesis; Safety Mode - Ottobock Kenevo 3C60 Gebrauchsanweisung

8 Additional operating states (modes)

The product automatically switches to special operating states (modes) when an error occurs, in
case of an empty battery or while charging. Functioning of the prosthesis is limited due to its
altered damping behaviour.

8.1 Empty battery mode

The joint emits beeps and vibration signals when the charge level is 15% or less (see Page 62).
Then the damping settings are set to high flexion resistance and low extension resistance, and the
product is switched off. Before switching to empty battery mode, warning signals are emitted at a
battery charge level below 35% (see Page 62).
You can switch back to basic mode from empty battery mode by charging the product.

8.2 Mode for charging the prosthesis

The product is non-functional during charging.
To switch to basic mode, the battery charger for the product must be disconnected after the bat­
tery is charged.

8.3 Safety mode

The product automatically switches to safety mode if a critical fault occurs (e.g. failure of a sensor
signal). Safety mode remains in effect until the error has been rectified.
A setting for high flexion resistance and low extension resistance is applied in safety mode. This
makes limited walking possible for the user even though the product is not active.
The switch to safety mode is indicated by beeps and vibration signals immediately prior to switch­
ing (see Page 62).
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.

8.4 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.
The hydraulic unit cannot overheat in activity mode A or B. Therefore, no overheating mode is
triggered in these two activity modes.
Overheating mode is indicated by a long vibration every 5 seconds.
The following functions are deactivated in overheating mode in activity mode C:
• Joint lock for use of a wheelchair (see Page 55)
• Battery level indication (see Page 48)

9 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.

10 Maintenance

INFORMATION
This component was tested for three million load cycles in accordance with ISO 10328.
Depending on the patient's 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 making
use of regular service inspections.
