Safety Mode; Cycling Mode - Ottobock 3E80 Instrucciones De Uso

3) Place the extended, unloaded prosthesis on an underlying base.
4) Connect the battery charger to the prosthetic knee joint.
→ A signal tone will be emitted. The resetting process will start automatically after the signal
tone ends.
→ Three signal tones will confirm the process has ended. The control settings for the pros­
thetic knee joint are now reset to their factory settings.
5) Disconnect the battery charger from the prosthetic knee joint.
6) Insert the battery into the prosthetic knee joint (see Page 15).
→ A signal tone will be emitted to indicate the prosthetic knee joint is ready for operation. The
control unit has to adjust to the patient by means of trial walking.

6.1 Safety mode

NOTICE
Contact of the product with a magnet
Functional limitations due to sensor malfunction
Do not bring the product into contact with magnets.
►
Safety mode is activated when the battery is almost drained or a system error occurs. Safety
mode activates stance phase damping permanently and thereby allows walking safely.
Switching to safety mode is indicated by signals (light, sound, vibration).
If safety mode has been activated due to an empty battery or a minor fault, the prosthetic knee
joint switches back to normal mode when the battery charger is plugged in.

6.2 Cycling mode

Cycling mode makes it possible to ride a bicycle with low flexion damping. Switching between the
modes (normal mode, cycling mode) is triggered by a movement pattern.
1) Bounce up and down on the forefoot 3x in quick succession while maintaining continuous
ground contact (see fig. 15). In this process, apply load to the foot to mimic walking then
noticeably ease the load in between steps without removing the foot from the floor.
→ Vibration signals and signal tones will indicate the upcoming change to the desired mode.
2) To switch modes, lift up the prosthesis for at least 2 seconds then extend it toward the rear
without making contact with the floor (see fig. 16).
→ The prosthetic knee joint confirms the switching process and switches to the other mode.
A dropping signal tone indicates a fault in the switching process.
