SECTION 1 SYSTEM OVERVIEW
Federal Law restricts that the Espire Elbow system is to be purchased,
configured and fit only by a board-certified prosthetist, licensed by the
state in which they practice. This device is intended for use in accordance
with the information contained in this document. Instruct the patient on
proper use of this device before transferring device to patient.
Intended Use Statement:
The Espire Elbow is to be used exclusively for external prosthetic fittings
of the upper limbs. The Espire Elbow processes the end-user’s input
signals to activate and control powered elbow movement.
1.1 INTRODUCTION
Thank you for purchasing the Espire Elbow system from College Park
Industries. The following pages will cover everything you need to know
about this system from setup to operation. If you have any questions,
concerns or comments, please contact our Technical Service team at
800 728 7950 (US/Canada), (+1) 586 294 7950 (International).
In the following document you will find information on everything from
fabrication to maintenance and care of the Espire Elbow system. Read
these instructions carefully and educate the end-user on all functions
of this product before final delivery. Espire is a tool designed to make
the lives of prosthetists and transhumeral (or above elbow) amputees
successful and productive.
The Espire Elbow is a state-of-the-art, internally powered, myoelectric
elbow prosthesis. Espire Pro uses electrical signals from muscles to
proportionally control a powered elbow and terminal devices, whereas
the Espire Hybrid uses electrical signals from muscles to control terminal
devices only. College Park does not recommend that the device contain
more than 3 degrees of freedom; the clinician should evaluate according
to the combination of terminal devices that are required by the patient.
The system’s versatility also allows many other control schemes such as
switches, linear transducers, pattern recognition systems, etc. Signals
from these inputs are processed by Espire’s internal microprocessor unit
and then sent to the respective devices.

SECTION 2
BATTERIES AND CHARGING
2.1 THE BATTERY
The Espire Elbow system is supplied with two removable lithium-ion
batteries. This battery supplies 3000 mAh at 11.1 volts for the elbow and
7.4 volts for the terminal device(s). It is advised to rotate use of these
batteries, keeping one as a spare for backup power. For most users, one
battery will last an entire day*, depending on the prosthetic components,
condition of the battery and the frequency of use.
The batteries are shipped with a partial-charge (up to 30%). We
recommend charging both batteries to 100% upon receiving the Espire
Elbow system.
*based on average use during an 8-hour period
Caution: Use only the College Park Industries manufactured Espire
Elbow battery pack and the provided battery charger with the Espire
Elbow system. Always follow the manufacturer’s instructions for proper
removal of and replacement of battery pack.
Note: If storing the Espire Elbow for an extended period without using,
remove battery pack from the elbow before storage.
2.2 BATTERY INSTALLATION AND REMOVAL
Batteries can be removed and replaced as necessary. To remove the
battery, simply push the battery cover clip and gently lift it o the
elbow. Use the pull tab to remove the battery.
Installing a battery is the reverse process. Insert the battery into the
elbow, ensuring that the pull tab is accessible for future removal. Then,
apply the battery cover. The battery cover clip will “click” into place
when seated.

2.3 LED INDICATOR
2.4 BATTERY CHARGER
The Espire Elbow is equipped with a state-of-charge indicator. This
indicator tells the user how much life is left in their current battery. The
Espire must be powered on to use this feature.
Press the power button for one second to activate the LED indicator light
on the forearm. The number of blinks indicates the state of the charge.

Yellow Solid Critically Low - Charge Battery
Espire Elbow systems are supplied with a Smart Charger for the
lithium-ion battery. The charger is recommended for daily use and will
assure that the battery will receive a full charge and provide maximum
running time. There are two charger types (single-bay or dual-bay) and
three power adapter options (US, UK, or European) to match the needs
of dierent regions. There is also a car charger available.
Caution: Using a dierent A/C adapter than the one provided with
your battery charger may cause damage to the Espire battery or
battery charger.

2.5 CHARGING THE BATTERY
Charging the Espire Elbow Battery
1. Place the charger on a flat, level sur face away from sources of heat and moisture.
Plug the A /C connector from the power supply into the back of the charger and
connect the power supply to the main A/C supply using the cable supplied.
2. If the battery you wish to charge is inside of the Espire Elbow, it must first be
removed from the batter y bay. Remove the battery cover via clip and remove the
batter y by using the pull tab.
3. Place the battery into the batter y bay ensuring that the 5-way connector is fully
seated. The LEDs in the status window will provide status information and the
charger will automatically begin charging.
Recharge time from empty is approximately 3.5 hours.

3.3 CONNECTING CABLES
TO THE INPUT BOARD
When attaching cables, note the proper orientation. The connectors
are “keyed” or asymmetrical to assure proper alignment. The connector
should plug in easily and is held in place with friction.
When removing cables, pull close to the connector to avoid pulling on the
wires. Wires that become loose could cause intermittent operation.
3.4 STRAIN RELIEF DISC
The strain relief disc prevents accidental disconnection of the input
wires and acts as a seal to prevent moisture and dirt from entering from
entering the area with the receptacles.
1. Thread the input wires through
the center hole of the disc, then
connect the wires to the board.
Apply silicone grease to the plug
connectors before inserting into the
board (see section 3.3).
2. Fasten the wires to the strain relief
disc using the provided zip-tie. This
is necessary to prevent accidental
wire disconnection.
Sealing the Input Board
3. Apply a small amount of silicone
grease at the perimeter seal
between the disc and the ring.
4. Line up the fastener holes on the
disc to the mounting threads on the
input board, then gently press the
disc to the board.
5. Use (2) M2 x 5mm fasteners and
washers to secure the disc to the
input board. A 1.3 mm Allen wrench
has been provided to tighten the
fasteners finger-snug
(2 in-lb / 0.23 N-m).
6. It is important to seal the holes
where the wires pass through
the strain relief disc before final
assembly of the socket. Apply RTV
silicone over the strain relief hole,
zip-tie hole, and wires.
