Switching From A Mymode Back To Basic Mode; Additional Operating States (Modes); Empty Battery Mode; Mode For Charging The Prosthesis - Otto Bock C-Leg 3C98-3 Instructions For Use Manual

Additional operating states (modes)

10.3 Switching from a MyMode back to basic mode

Information on switching
• Regardless of the configuration of additional MyModes in the adjustment software, it is always possible to
switch back to basic mode (mode 1) with a motion pattern.
• It is always possible to switch back to basic mode (mode 1) by connecting/disconnecting the battery charger.
• Before the first step, always check whether the selected mode corresponds to the required motion type.
If the Volume parameter is set to "0" in the Cockpit app, there are no beep signals (see page 39).

Switching process
3x – 5x 1s
ð
1) Position the prosthetic leg back slightly.
2) While maintaining constant contact with the floor, bounce on the forefoot at least 3 times but not more than
5 times.
3) Keep the prosthetic leg still in this position (lunge position) for about 1 second without lifting the leg. Taking the
weight off is no longer necessary.
→ A beep and vibration signal will occur to confirm that the movement pattern has been recognised.
INFORMATION: If this beep and vibration signal is not emitted, the requirements were not met
while bouncing.
4) Move the prosthetic leg in next to the contralateral leg, set it down and keep it still for approx. 1 second.
→ A confirmation signal will sound to indicate that the prosthesis has successfully switched over to basic mode.
INFORMATION: If this confirmation signal does not sound, the leg with the prosthesis was not cor­
rectly repositioned and kept still. Repeat the process to correctly switch to the required mode.
11 Additional operating states (modes)

11.1 Empty battery mode

Beeps and vibration signals are emitted if the available battery charge level is 0% (see page 51). 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 the safety mode resistance values. These 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 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 product is not active.
The switch to safety mode is indicated by beeps and vibration signals immediately prior to switching (see page 51).
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), the
flexion resistance 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 settings that existed prior to overheating mode.
