Additional Operating States (Modes); Empty Battery Mode; Mode For Charging The Prosthesis; Safety Mode - Otto Bock Kenevo 3C60 Instructions For Use Manual

INFORMATION
If too much time passes between connecting and disconnecting (e.g. a vibration signal is already emitted), the
process of connecting and disconnecting 3 times has to be repeated.
Switching on
1) Connect the power supply with battery charger to the outlet.
2) Connect the battery charger to the product.
→ The correct connection of the battery charger to the product is indicated by feedback (see Page 38).

9 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.

9.1 Empty battery mode

The joint emits beeps and vibration signals when the charge level is 15% or less (see Page 37). 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 37).
You can switch back to basic mode from empty battery mode by charging the product.

9.2 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 battery is charged.

9.3 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 switching (see Page 37).
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.

9.4 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.
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 30)
• Battery level indication (see Page 19)

10 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.

11 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 ser­
vice inspections.
