• Attach Velcro to the socket and the corresponding surface on the battery. (Figure C)
• Press down the battery pack for secure attachment.
• Reinforce the attachment of the battery module by wrapping the battery to the socket with electrical tape
or similar.
Make sure the connection cable lies flat against the surface of the prosthesis because a loose cable can get
caught. Observe the cable position during walking and make changes to the assembly if necessary.
DEFINITIVE SOCKET: BATTERY ASSEMBLY
• Mark the best suitable position of the battery pack identified during diagnostic socket fitting (see chapter
“Diagnostic socket: battery assembly”).
• Recommendation: Position the battery pack as proximal as possible on the rear aspect of the socket.
• Check the position using the dummy (Figure D).
• Follow the common lamination guidelines and position the lamination dummy as marked, with the curved
side facing towards the socket before applying the final layer.
• Proceed with lamination as usual.
• After the lamination has cured expose and remove the dummy (Figure E).
• Apply double-sided tape on the imprinted area and attach the battery pack by pressing both surfaces
together.
• Wrap any excess length of the battery connection cable around the pylon or socket connector. Make sure
that the connection cable does not interfere with actuator motion. Observe the cable position during
walking and make changes if necessary to the assembly.
BENCH ALIGNMENT (Figure F)
Overview
• Fit the foot with the selected cover and shoe.
• Power ON (see chapter “Power ON”).
• Adjust the Heel Height to the preferred shoe (see chapter “Heel Height Adjustment”).
• Proceed with alignment and corrections above the foot level.
• Establish the correct height of the prosthesis using the appropriate components.
• Ensure that the alignment is correct in the sagittal and coronal planes. In the sagittal plane, the alignment
reference line should bisect the center of the socket at MPT and pass through the posterior middle /
mark on the foot module.
DYNAMIC ALIGNMENT AND USE OF HEEL WEDGES
Optimum functional benefits will only be achieved when the rollover function is optimized. The heel wedge
can influence the heel- to-toe function. Start changing the heel resistance to improve foot response adding a
heel wedge. The °, ° & ° wedges can be interchanged to customize the stiffness of the heel and achieve
the desired functional characteristics. A combination of wedges may be used. Have the user walk on even
ground and assess proper heel-to-toe function.
Temporary Wedge Placement (Figure G)
• Cut the wedge to the width of the foot module.
• Roughen the upper and lower surface of the wedge with abrasive paper.
• Place the wedge in the angle of the heel and foot module.
• Secure the wedge in position with tape wrapped around the foot module.
Permanently fix wedges when ® is used for more than a couple of days.
Temporarily fitted wedges will move out of position and cause functional issues.
Failure to do so can void the warranty.
10
Permanent Wedge Placement (Figure H)
• Apply adhesive to the upper side of the wedge only.
• Locate it in the foot/heel junction and position it before the adhesive sets.
• For split toe feet first install the heel wedge, then remove a thin slice in the middle by cutting with a sharp
knife through the split in the carbon foot module.
• Complete the dynamic alignment by performing calibration. (See chapter “Calibration”)
HEEL DIVIDER
The heel divider should be placed in the posterior portion of the split heel. To secure its position, a drop of
instant adhesive can be used on one side.
Flex-foot sock FCX63007 (Figure I)
To protect the cover a Flex-Foot sock is fitted over the foot module before applying the cover. The sock
should fit loosely in the heel area. To hold the Flex-Foot® sock in place attach the self adhesive velcro tabs to
the sides and front of the ankle. Press the Flex-Foot® sock firmly onto the tabs to hold in place.
It is important that the Flex-Foot® sock doesn’t slip down as this will cause interference with the
® function and performance.
FOOT COVER REMOVAL (Figure J)
To remove the foot cover, grasp and pull on the Flex-Foot Sock. Hold down the cosmetic cover with a hand
on the rear aspect of the cosmetic cover. The heel module will snap out of the heel clip. Continue to pull and
remove the foot completely.

gait. During calibration, ® recognizes the user’s specific gait parameters, allowing for accurate and
consistent terrain detection. For calibration the user must walk on level ground for at least consecutive strides
without interruption.
• Have the user stand still.
• Make sure the keypad is active.
»The LED blinks green and yellow (The keypad will lock
automatically after 60 sec. of use).
• Make sure the user has access to a path on level ground long
enough to complete at least strides without interruption.
• To enable Calibration, hold down and press nine times.
»The system confirms with a beep and a vibration.
»The LED blinks green and yellow.
• Have the user walk on level ground at a self-selected walking
speed until completion of calibration is confirmed by a beep
and vibration.
»The LED blinks green.
»The system is now properly calibrated to the user and enabled for
normal adaptive functions.
: Make sure the surface is completely flat. It is
recommended that calibration is performed on an indoor surface. No sharp turns should be taken during
calibration.
: The user may take gentle turns during the calibration walk. If the calibration is not completed after
approximately strides, see below.
TROUBLESHOOTING
• Ensure the correct alignment.
• Ensure there are no extreme gait deviations, such as significant circumduction or rotation, as this may
prevent the completion of calibration.
• Ensure consistent walking speed.
• Avoid walking in a circle or sharp curves.
• If calibration is not confirmed after strides, you must perform calibration again.
• If the alignment is changed you must perform the calibration again.

FUNCTIONS
INCLINES/DECLINES
• During ramp ascent, ® gradually raises the toe of the prosthetic foot. Adaptation begins on
the second step and makes small changes until it reaches the gradient of the ramp. ®
continuously adapts on every step.
»Dorsiflexion of the foot during ramp ascent reduces socket pressure and strain on the ligaments.
• During the swing phase, ® will raise the toe to provide additional ground clearance.
• It is not necessary to lead with a particular limb when ascending ramps.
• During ramp descent, ® lowers the toe of the prosthetic foot.
»This helps to increase safety and gives better support during roll over of the prosthetic side.
: Steep inclines or declines (above °) may trigger stair response resulting in unexpected
ankle adaptation.
STAIRS
• During stair ascent, ® will raise the toe.
This will facilitate stair ambulation and improve gait
symmetry.
• When leading with the prosthetic side,
® will adapt to this position after the second
prosthetic step on the stairs.
: Pay attention to transitions from and to
stairs.
When ® is activated for the first time, the
default manufacturer settings will be enabled. In the
default manufacturer settings, the stair response is
preset to ° dorsiflexion.

MODE hold down and press five times.
»The system confirms with a single beep and vibration.
• Initiate RELAX MODE in a sitting position by
extending the knee for at least seconds.
»This provides a more natural ankle position when sitting
with the lower leg extended.
Following the Relax Mode the ® will move
into CHAIR EXIT MODE.
To initiate this use one of the following methods:
. Tap the heel of the foot.
. Flex the knee and place the foot beneath the chair. Lift the foot to allow the adjustment to take place.
The ankle will move to dorsiflexion that will enable the user to bring the leg further back, providing more
controlled transition from sitting to standing. The ankle will move back to neutral after the first step.
Tapping on the heel will move ® to the next mode, i.e. tapping the heel when in RELAX MODE
will move ® direct into CHAIR EXIT MODE. A second tap on the heel will move
® further to neutral ready for walking.

TRAINING TIPS
Start the training after the ® is aligned and calibrated.
Ensure full function with all connections secured.
Charging: Train the user on how to charge the unit.
Heel height
adjustment:
Encourage the user to switch shoes or try out barefoot walking using the heel height adjustment.
Curbs: Ask the user to take a long step onto and down a curb. This will limit the ankle adaptation. This will
prevent false ankle adaptation.
Note: Walking across high curbs may initiate the stair response!
Sitting: Ask the user to sit down and position the shank at over ° relative to the ground (stretch legs). To allow
for the Relax Mode the prosthesis has to be slightly unloaded PROPRIO FOOT will move into a plantar
flexed position (toe down).
Chair Exit Mode: Ask the user while in a seated position to move the prosthesis under or close to the chair. PROPRIO FOOT
will dorsiflex (toe up) to facilitate standing up.
Level ground: Ask the user to walk at slow and fast speed. Observe the dorsiflexion in swing.
Ramps: Ask the user to walk up and down on a shallow and steep ramp. Observe the ankle adaptation and ask
whether the user can sense it.
Stairs: Ask the user to walk up and down on stairs. Advise to lead with the prosthetic side upstairs and to lead
with the prosthetic side when going down. This will provide stair adaptation after the first step on stairs.
Note: Instruct the user to be careful walking downstairs for the first time, since they will not be used to the
dorsiflexed ankle position. Encourage the user to switch shoes or try out barefoot walking using the heel
height adjustment.
Toe lift: Very slow walking speed won’t trigger toe lift.
Half step: Sharp turns, zigzagging or stepping up high curbs may cause dorsiflexion.
Power loss: Results in plantarflexion.
Motor stuck: Light tapping on the toe or heel can free it up.
