Hero Arm and the diagrams in this manual. The Hero Arm comes with either a 3 Motor or 4 Motor Hand depending on the most suitable size of hand for your arm. The key differences are the reduced size of the 3 Motor version, and the number of tendons.

Every socket is designed and 3D printed for each individual based on a 3D scan of their residual limb, and comes in two different layouts: internal or external battery. The functionality of both layouts are the same, but they have some noticeable cosmetic differences as shown below:...
Health and Safety representative and conduct a formal risk assessment. You can use your Hero arm above -5 °C (23 °F) and below +50 °C (122 °F). You can use it at pressures equivalent to altitudes of up to 4000 m (16,400 ft, that’s 600 hPa to be exact), making it safe to use in the cabin of a commercial airliner.
Your Hero Arm has been designed to perfectly fit your arm, and comes with an adjustable BOA Fit System™ to reach the perfect balance of comfort and secure fit. You can easily adjust the fit of your Hero Arm throughout the day without removing it, simply by adjusting the BOA Dial.
Charging the Battery Your Hero Arm comes with a battery and Smart Charger. The battery life of your arm will vary depending on how heavily you use it, but we recommend charging it every night. You must remove the battery from the arm before charging. For safety reasons, only ever charge your battery using the Smart Charger provided with your arm.
Checking the Battery Status To check the status of the battery, with your Hero Arm switched on, hold the Hand Button down for 1 second. The battery life is indicated by the colour of the Hand Button: How to use your Hero Arm...

However, if you only have one suitable muscle site on your residual limb, your Hero Arm may only use a single EMG sensor. If this is the case, the way you control the arm will be different. The control scheme for...
The information on the following two pages (p11-12) only applies to users with a single muscle site. For the vast majority of Hero Arm users (with two muscle sites) the information in Controlling the Hand applies instead. Controlling the Hand - Single Site Users Only When you tense the muscles under your sensor, the Hero Arm swaps between opening, then closing the fingers.
Page 15
After picking it up, the hand will swap direction to opening, so your next muscle tense will release it. To tighten your grip on an object you must put it down (or otherwise support it), release it with your Hero Arm, then re-grip it from scratch.
Grip Modes The Hero Hand has 4 different grip patterns in the 3 motor version, and 6 different grips in the 4 motor version. These grips are grouped together in pairs to make switching between them quick and easy. Changing Grips To switch between grips within a group, move the hand into the open position, relax, then hold an open signal for more than a second (see Controlling the...
Group 1 - Fist and Hook The primary group contains the Fist and Hook grips: Fist This grip is useful for carrying round objects such as bottles or fruit, for holding utensils and handles, and can also be used for handshakes. First, the thumb closes, followed by all 4 fingers.
Group 2 - Tripod The secondary group contains two Tripod Grips. These are useful for picking up and manipulating small objects, such as car keys, coins, jar lids, pens etc. Tripod A The middle and index fingers close to meet the thumb. The ring and little fingers remain open.
Group 3 - Pinch The final group, only available on the 4 Motor versions of the hand, contains two Pinch Grips. The Pinch Grips are useful for manipulating small objects or picking things up off a table such as a coin or pen. The pinch grips work with the thumb knuckle in both the closed and open positions - if you’re finding it difficult to pick up a small object, try moving the thumb knuckle (see Thumb Flexion...
Freeze Mode Freeze Mode can be used with any of the grip patterns to temporarily freeze the position of the hand and disable the muscle control - this allows you to set a grip position without worrying about accidentally sending a muscle signal and releasing your grip.
In addition to the powered movement of the thumb, the knuckle can also be manually adjusted into either the open, middle or closed position. Fully closing the thumb makes it easier to pull the Hero Arm through the sleeves of clothing. The middle thumb position can be useful for picking up small objects:...
Calibration When you power on your Hero Arm for the very first time, the hand may perform a calibration routine - this will involve closing each of the fingers and the thumb in order to check everything is working correctly. It is important that the fingers are not obstructed during calibration, as this could cause the calibration to fail.
Covers Your Hero Arm can be customised with swappable covers, to match your style or mood. There are 3 types of cover: hand cover; arm covers (split into two halves) and battery cover. Each cover is custom designed to fit your Hero Arm perfectly.
Page 24
Depending on whether you have an internal or external battery style Hero Arm, your arm covers will look slightly different. Older versions of the Hero arm use a hook-and-loop pad to attach the covers. To attach the battery and arm covers, line up the fastening pads on your cover with those on your arm, and press the cover firmly into place - you should hear a click...
Hero Arm which might subject it to excessive impacts or force, we would recommend first discussing this with your prosthetist. Your Hero Arm can withstand splashes of water (such as light rain), however it is not water resistant. Do not submerge your Hero Arm in water - it should be protected from moisture at all times.
The Hero Arm can be cleaned using alcohol-free antibacterial wipes. In addition, the flexible internal socket is easily removable from the frame of your Hero Arm to make cleaning easy. You should clean the flexible socket using warm, soapy water on a regular basis.
We recommend you clean your socket daily, and the rest of the device as needed. If you find that you struggle to clean part of your Hero Arm, discuss the matter with your prosthetist.
