HOW TO TURN THE DEVICE OFF (Figure 1)
To turn the device off press the ON/OFF button and hold it down until you hear 4 short beeps and 1 long beep.
When the device is off, the light indicator on the user interface panel will also turn off.

CALIBRATING THE DEVICE

REQUIREMENTS FOR CALIBRATION
In order to calibrate the device, the accompanying software is required (RHEOLOGIC software for PCs, Össur
Logic app for iOS devices)
The accompanying software technical manuals give instructions on how to connect to the software and modify
adjustable parameters for the device.
HOW TO CALIBRATE THE DEVICE
1. Before starting make sure there is NO LOAD on the knee and DO NOT connect the socket to the knee.
2. Make sure the knee is FULLY extended.
3. Connect to the knee using the accompanying software.
4. Open the "Calibrate" tab in the accompanying software and press the "Calibrate" button.
5. When calibration is complete the device will provide a sound / vibration signal.
The following values are acceptable calibration ranges:
• Toe load (-2.5 to 2.5)
• Heel load (-2.5 to 2.5)
WARNING: Improper calibration (for example if load is applied on the knee or socket is connected) affects the
knee's ability to perform optimally and may compromise the user's safety.
RECOMMENDED ALIGNMENT OF THE DEVICE
RECOMMENDED COMPONENT SELECTION
Please refer to the list of recommended components for the device in the Össur catalog.
BENCH ALIGNMENT
1. Connect the device to the foot (with the foot cover on) using corresponding Össur adapters / connectors.
2. Establish knee center height.
3. Mount the socket to the device using corresponding Össur adapters / connectors.
4. The alignment reference line should pass through a sagittal plane bisection of the socket, the knee center and
the posterior 1⁄3 of the foot. (Figure 2)
NOTE: If stability modifications are desired after patient assessment; the reference line can be shifted up to 5 mm
(3/16") anterior or 5 mm (3/16") posterior to the knee center.
CAUTION: As the alignment reference line is positioned more posterior to knee center, the user will experience
more stance flexion during loading response. Additional voluntary control will be required to maintain knee
stability when the device is powered OFF.
PRECAUTION: At maximum flexion, maintain minimum distance of 3 mm (1⁄8") between the device and the
socket. At maximum flexion where contact cannot be avoided due to socket volume, make sure that the contact is
on the frame, directly below the user interface panel. For maximum pressure distribution maintain a flat and
cushioned contact surface (Figure 2).
STATIC ALIGNMENT
1. Ask the user to stand with equal weight on each foot and make sure that the pelvis is level (Figure 5).
