There are no field-serviceable parts inside the
Vacuum Pump. Opening the Vacuum Pump or
charger may result in injury or death and will
void the warranty.
Unauthorized changes or modifications to the
LimbLogic pump or accessories may; impair their
function resulting in injury or death, will void the
warranty, and may prevent their compliance with
relevant standards.
This pump is only designed to move air; use of
Vaseline®or similar lubricating creams inside the
socket will clog the pump. Do not allow foreign
substances to be pulled through the Vacuum Pump.
This may impair function of your vacuum system.
Do not allow acetone to contact the Vacuum Pump or fob.
All LimbLogic components have passed safety
testing for use as medical devices. Radio enabled
devices comply with United States and international
guidelines for low power transceivers. If LimbLogic
components will be used around safety critical
devices such as pacemakers or defibrillators, consult
the manufacturer for appropriate usage instructions.
Failure to do so may result in injury or death. Consult
the section on Regulatory Information for more
information on safety and compliance.
LimbLogic is designed for use by a single patient only.
Use on more than one patient may result in cross-
contamination potentially causing a serious infection.
Charge the Vacuum Pump in a well-ventilated area
at a temperature between 5 °C (41 °F) and 33 °C
(90 °F). Failure to do so may result in prolonged or
incomplete charging of the Vacuum Pump and
may damage the Vacuum Pump.
A Vacuum Pump enclosed by a cosmetic cover will
retain heat, but in most cases should charge
normally at temperatures below 27 °C (80 °F). The
battery may not fully charge at higher temperatures.
Use of the LimbLogic at temperatures above 41 °C
(106 °F) may heat the surface of the product to
unsafe temperatures which could cause burns with
extended contact. Use care when operating the
LimbLogic at high temperatures.
LimbLogic has been constructed using polymer
materials to create a durable, lightweight, water-
tight, and radio-transparent design. These materials
have all been certified to an inflammability rating of
at least HB per UL 94. However, polymers can melt
or burn if exposed to high temperatures or flame.
Do not expose your LimbLogic product to these
conditions. Doing so may result in ignition resulting
in injury or death.
LimbLogic pumps cannot compensate for failures in
the associated prosthetic socket or sealing system.
Only use LimbLogic pumps with commercially proven
socket and sealing systems. Use with other sealing
systems may result in loss of suspension resulting in
injury or death.
Electrical equipment can interact. Do not operate
the fob, charger, or either LimbLogic pump design
while they are stacked upon, or in close proximity
to, other electrical equipment without monitoring
performance. Doing so may result in equipment
malfunction or failure.

Overview
INSTALLING THE FOB BATTERY
The fob uses a commercially available CR2032 coin cell battery.
The battery that is shipped with the system must be installed prior
to using the fob.
The battery will normally have to be replaced every 3 months
depending upon how much the fob is used.
The fob case can be pried open using a small flat blade screw-
driver, then snapped back together starting at the battery end
and working back toward the opposite end.
The fob battery could cause serious injury or death
including choking. Keep coin cell type batteries away
from children.
After the battery is replaced, the system does a quick
check by illuminating all the LED indicators. If all of the
LEDs do not illuminate, then either the battery or the
LEDs are not working, or the battery has been installed
upside-down.

INTRODUCTION
LimbLogic is a remote-controlled vacuum
suspension system that is completely
integrated into the prosthesis without the
annoyances of tubes in the socket. The
Side Mount pump mounts on the side
of the patient’s socket, while the Distal
Mount pump mounts inline on the pa-
tient’s socket. LimbLogic operates quietly
and features “Set and Forget” monitoring,
which means that the system monitors
the level ofvacuum in the socket so as to
maintain a secure and comfortable fit.
The miniaturized LimbLogic fob provides the user with control
and status information for the LimbLogic System. The fob uses
lights or digits to display the Vacuum Pump’s current usage
mode, the battery level, the current vacuum level, and leak
indicators. The vacuum level and range can be changed using
the buttons located on the fob.
VACUUM SYSTEM FUNCTION
The system monitors the vacuum level and draws more vacuum
as needed to maintain the level within a designated Vacuum
Range. The desired vacuum level, also known as the Vacuum
Set Point, is the upper limit of this range, and can be adjusted
by the patient; however, the Vacuum Set Point is limited by the
User Maximum setting.
The system is shipped with the Vacuum Range set at 4 and
the User Maximum set at 20, but if those settings are not
suitable for your patient, you may adjust them as desired.
The User Maximum cannot be set higher than the system
maximum of 20.
The optimum vacuum setting is dierent for each amputee.
Keep in mind that a higher vacuum level is not always better.
Higher vacuum levels require that the Vacuum Pump use
more power and will therefore discharge the battery faster.
PATIENT BRIEFING
The LimbLogic pump has been designed and tested for durability and
usage in common environments. While unlikely to result in unsafe
performance, there are extreme conditions which may affect the
LimbLogic’s function.
Be sure to train patients:
• Not to use their LimbLogic in corrosive environments, such as
salt water.
• Not to use the LimbLogic outside of its specified range of
environmental conditions. (Refer to “Performance
Characteristics” on page 31.)
• How to start, stop, and reset their pump in the event of
malfunctions caused by unusual conditions such as Electrostatic
Discharge, such as experienced after walking across carpet;
or extreme electric fields, such as those caused by power
transformers, or large electric equipment.
• How to release the vacuum in their socket.
• To obtain medical attention in the even of an open wound on
their residual limb.
• How to contact you, as WillowWood’s representative to this
patient, in the event that they have questions about the
configuration, use, or maintenance of their LimbLogic.

4. When charging is complete, the Node LED will flash.
Disconnect the Charger from the Vacuum Pump and from
the power outlet.
When you are ready for the pump to begin regulating the
vacuum, either turn on the fob (refer to page 11) or press the
on/o button on the Vacuum Pump. The pump will operate
until the preselected vacuum level is reached.
Note: Your pump can be used while charging. If the pump has
just been unplugged from the Charger, it will be in Standby State
(refer to page 11). To resume vacuum regulation, press the on/o
button one time for Active State. Press again to turn the pump o.
Walking while charging your pump may cause you to trip
and fall. Do NOT walk while your LimbLogic is plugged into
the charger.
Use ONLY a WillowWood Charger. Use of any other charger
may result in damage to the Vacuum Pump or the charger
or both and may negatively aect EMC performance and/
or compliance and may result in serious injury or death.
The charger may pose both a strangulation and/or
electrocution hazard and should not be handled by children.
Do not use the Charger near water. The Charger is
not waterproof. Use of the charger near water may
result in serious injury or death.

installed:
1. Remove the existing tube from the Exhaust Tube Fitting.
2. Cut the existing tube just past the Muer.
3. Connect the Exhaust Tube Fitting to the section of tube that
does not have the Muer. The pump will function normally,
but at a slightly higher noise level.
POTENTIAL HOME USE CHALLENGES
Your pump, fob, and charger are unlikely to be damaged by
exposure to lint, dust, or light. However, charging the pump
while it is sitting in direct sunlight or near a furnace vent may

not beep when
the on/o button
is pressed and
the Charger is
not connected to
the pump.
• The pump’s internal battery may not
be charged. Charge the pump with the
Charger for at least 30 minutes and try
again.

your product. However, if the plug is too
loose, replace the rubber ring.
The pump makes
a “zip zip zip”
sound as it
controls the
vacuum.
The system is leaking, but not yet at a
rate that triggers the Leak Detector light.
Wash debris from sealing surfaces, and
remove any dirt or debris from the sealing
surface for the sealing gasket and the
pump’s sealing surface. If the leak is still
present, use the Diagnostic Disc or Sheet
to determine the source of the leak. Refer
to the manufacturer of your socket system
for further suggestions on locating leaks.

Problem Action
Pressing the
center button of
the fob does not
cause the yellow
LEDs to light in a
“chasing”
pattern.
The battery is likely dead and must be
replaced per the instructions on page 5.
The fob does not
communicate
with the pump.
The “chasing”
pattern of LEDs
ends after 6
seconds, and the
LEDs turn o.
• Wait one minute for the fob screen to
turn o. Make sure the pump is on by
pressing the on/o button and verify
that the pump beeps once. Listen for
about 30 seconds to make sure that the
pump doesn’t quickly beep several times
and turn o, which indicates a battery
problem. Press the fob center button
again.
• The fob may be too close or too far
from the pump. Place the fob about
2 feet away from the pump, and press
