•Please read this instruction manual thoroughly before using.
•Failure to comply with safety precautions can result in the
QUATTRO malfunctioning and risk of injury to the user.
•Initial operation of the QUATTRO should take place in the
presence of a trained care professional.
•Do not open or modify any component(s) and DO NOT make
repairs on the QUATTRO unless otherwise directed in this IFU.
•If any issues or concerns with the QUATTRO arise, contact
your Prosthetist for assistance.
•Improper and unsafe use of QUATTRO may result in injury.
•Do not use the QUATTRO while the battery is charging via the
wall charger. Be sure to disconnect from the charger prior to
putting on the prosthesis.
- Do not submerge Quattro while charging using the
Quattro Booster Battery Pack.
•If unusual movement or wear is detected in a structural part
of the prosthesis at any time, immediately discontinue use
of the device and consult your Prosthetist.
•The QUATTRO contains a Lithium-ion battery that is not eld
replaceable and requires factory service for repair. Lithium-ion
batteries contain hazardous metals and should never be
disposed of in residential or commercial garbage. They
should never be incinerated because they may explode.
Reference local regulations for proper disposal of product.
•If power is lost from the QUATTRO knee, it will default to
the Power-O Flexion resistance setting.
•When the battery is depleted, use extreme caution when
descending ramps and stairs.
•The QUATTRO contains small parts and cords that can be
potential choking hazards.
•If the QUATTRO has been stored outside its Operating
Temperature Range, allow the knee to acclimate to the
operating environment for a minimum of 30 minutes
before use.
•Avoid running or other intense physical exercise above the
specied operating temperature limit (45 °C [113 °F]). This
can damage your QUATTRO.
•The proximal connection to the patient is the Applied Part of
the device. All other external surfaces of the device, including
the power supply and cord, are the Accessible Parts.
•Failure to comply with the instruction for use will void the
warranty.

11.10. Modes
Sitting Mode:
The QUATTRO features two available behaviors when sitting, and
the adjustment is found under the “Tools” tab along the bottom
of the GaitLab and Freedom Innovations apps. With Sitting Mode
turned on (default), when the knee is unweighted and the thigh
reaches a 90 degree angle or greater, the knee exes without
resistance. With Sitting Mode o, the knee will continue to have
hydraulic resistance to exion independent of thigh exion angle.
Note: if Sitting mode is turned o, it will also disable Cycle Mode
and Obstacle Assist.
Obstacle Assist:
Obstacle Assist can be turned o or on during full programming,
and in the GaitLab App under “Setup” and “Adjust” after full
programming is completed. With Obstacle Assist turned on
(default), the knee will ex with no resistance when the thigh
reaches 35 degrees of exion or greater and is unweighted. This
is helpful for stepping over tall objects or entering a high vehicle.
When Obstacle Assist is turned o, the knee will ex slowly with
hydraulic resistance when unweighted independent of thigh
exion angle. Note: if Sitting Mode is turned o, it will also disable
Obstacle Assist.
Cycling Mode:
In Cycling Mode, the Knee will enter in low resistance when the user’s
thigh is near the horizontal plane (this position occurs when getting
on the bike or during normal pedaling). The Knee will remain in low
resistance until the user puts weight on the unit in full extension
(triggering the QUATTRO to return to normal walking mode).
Note: if Sitting mode is turned o, it will also disable Cycle Mode.
Golf Mode:
Golf Mode allows you to limit the amount your knee exes while
playing golf. After selecting golf mode in the Freedom app as the
alternate mode, navigate to the adjustment screen. On this screen you
will have 3 choices for dierent degrees of exion that will be allowed.

PROTEOR | FREEDOM QUATTRO | Instructions for Use
17
Each of these can be customized by pressing the“+”or“-“.This allows
you to have 3 custom settings for the amount of exion needed for
a particular golf swing.
!IN GOLF MODE THE KNEE WILL ONLY FLEX TO
THE DEGREE THAT HAS BEEN CHOSEN IN THE APP. DESCENDING
STAIRS AND SLOPES SHOULD BE AVOIDED WHEN IN GOLF MODE.
Stance Lock:
The QUATTRO features a Stance Lock for stability on a exed knee.
When the user stops the thigh at a exion angle and weights
the knee, it will automatically lock further exion. The lock will
automatically disengage when the thigh moves in an extension
moment or the knee is unweighted.
Note: Stance Lock is available from 0-70°of exion.
Engaging the Flexion Lock:
To engage exion lock, in any Activity Mode, double click the
mode button to engage the exion lock. The button lights up
with a solid white light to indicate that the Flexion Lock is engaged.
When the lock is engaged, the knee can straighten but
it cannot bend any further than the current angle. If the knee
is straightened to a more upright position, the lock re-engages
at the new angle.The knee will remain locked at this position
until the knee is straightened or the exion lock is disengaged.
The solid white light remains on as long as the Flexion Lock is
engaged.
Note:When theFlexionLockis engagedandtheknee isunweighted,
it will be locked in both exion and extension.
Disengaging the Flexion Lock:
With the lock engaged, double click the mode button to disengage
the Flexion Lock. The solid white light now turns o, indicating
that the Flexion Lock has disengaged.The knee returns
to the currently selected Activity, i.e. Walking.
Note: Stance Lock is available from 0-70° of exion.

Removing the Knee Cap
a. Use a 3/32”Hex Key to
remove the two socket head
cap screws from the Knee
Installing the Knee Cap
b. Install Knee Cap as indicated
below. Tighten the 2 socket

11.11. Power-O Behavior
When the battery is depleted or the knee has been put into
storage mode, a Power-O Flexion resistance is used. The
power-o exion resistance can be adjusted to accommodate
dierent user preferences and weights.
!
PLEASE HAVE YOUR PROSTHETIST ADJUSTTHIS
SETTING FOR YOU.
Making an Adjustment:
With the QUATTRO knee fully extended, insert a 3mm
hex wrench into the power-off flexion resistance screw: CW
adjustments provide more exion resistance and CCW
adjustments provide less exion resistance.

Note: The knee ships with

13 | AlignmentandSetup
Follow the Clinician User Guide and the GaitLab smartphone
app to properly align and setup the device. GaitLab is required
to calibrate and optimize the microprocessor settings for
each patient. Verify the smartphone requirements before app
installation. Download Apps from the App Store or Google Play
Store.
GaitLab App (
for Clinicians )
Freedom Innovations (
for Patients ):
14 | Cleaning
Use clean tap water to rinse o your QUATTRO knee. A soft-
bristled brush (such as a toothbrush) is acceptable to dislodge
stuck dirt on the outside of the knee only. Using any other
chemicals or soaps on the QUATTRO may void the warranty.
Dry the knee thoroughly with a towel after rinsing. Do not use
a hairdryer, which may damage the electronics and void the
warranty.
15 | Transferring Settings/Resetting to Factory
Defaults
1. Connect to the knee you’d like to transfer the program
from. Once connected, go to the “Tools” tab along the
bottom of the app, then tap “Manage Settings”. Tap
“Copy settings” to save the settings to your device. You
can now disconnect from the programmed knee.
2. Connect to the knee you’d like to transfer the program
to. Go to the “Tools” tab along the bottom of the app,
tap “Manage Settings”, and tap “Paste settings”. You will
get a conrmation message “Are you sure you want to
replace all settings?” Tap “OK” to transfer all settings, and
“Cancel”to cancel the paste and keep the settings as is.
• Reset to factory defaults: this will reset all of the settings
in the knee to factory settings.
• Recommendation: Have the patient sitting while
transferring the program or resetting the knee for safety.
