  • Page 6: Hello

    HELLO!
  • Page 7 Congratulations on your new Boston Digital Arm system! The following guide will provide you information, tips, warnings and troubleshooting to help you get the most out of your new arm every day.
  • Page 8: Fitting & Operation

    FITTING & OPERATION:...
  • Page 9 Your socket and harness are very important in allowing you to get the most out of your Boston Digital Arm. The Digital Arm relies on myoelectrodes, touch pads, switches, or a combination of all of them. If your socket and harness do not fit well, it will be difficult to control your Digital Arm.
  • Page 10: Strength

    STRENGTH - HOW MUCH CAN IT LIFT? Active Lift Your Boston Digital Arm is designed for an active lift of 10lbs. (4.5kg) when the forearm is one foot (30.5cm) long. This weight includes any devices attached to the end of the arm, such as wrist rotators and hands.

    ON-OFF SWITCH The on-off switch for your Boston Digital Arm is located on the left side of the removable battery. To turn your system on, press the button until it clicks and stays depressed. To turn it off, simply press the button again. Tip: Be sure to switch your Digital Arm off whenever you remove your prosthesis.
  • Page 13: Free Swing Feature

    FREE SWING FEATURE The Free Swing feature of your Boston Digital Arm allows you a natural swing for activities such as walking, when you don’t need the elbow motor to operate. The lever to operate this feature is located on the right side of the Digital Arm. To allow Free Swing, slide the lever away from the joint.

    BATTERY & BATTERY CHARGING:...
  • Page 15: Battery

    BATTERY Your Boston Digital Arm comes supplied with two removable and interchangeable Lithium-Ion batteries. For most users, one battery is adequate to last an entire day of normal use. Battery life will vary depending on the frequency of use, as well as the additional components drawing from it, such as wrist rotators and hands.
  • Page 16: Battery Installation & Removal

    BATTERY INSTALLATION & REMOVAL To remove the battery, simply press the release tab and gently lift the front edge of the battery. There are hinge pins on the end towards the elbow, so keep lifting until the battery comes off the hinge. To install the battery, just place the end opposite the tab into the opening.
  • Page 17: Battery State Of Change Indicator

    BATTERY STATE OF CHARGE INDICATOR Your Boston Digital Arm battery has an LED indicator telling you how much charge is left in the battery. To check the charge of your battery, just power on the Arm and the LED will blink, indicating the amount of charge remaining.
  • Page 18: Battery Charger

    BATTERY CHARGER Your Boston Digital Arm is supplied with a Fast Charger for the Digital Arm batteries. Unlike old batteries, your Digital Arm batteries have no “memory” and can be charged at any state and will retain its full capacity potential. The Fast Charger is recommended for daily use and will ensure a full charge.

  • Page 20: Charging The Battery

    CHARGING THE BATTERY We recommend you recharge your Boston Digital Arm battery daily. If the battery begins to emit the “low battery” alarm sounds, immediately power off your prosthesis and charge the battery, or replace it with a charged one. The battery can be charged with the included Fast Charger, or in the Digital Arm itself.
  • Page 21 Tip: Try to remember to turn off your Digital Arm when it is not in use. Leaving the arm on idle can affect the life of the battery. Lithium-Ion batteries will lose power after time even when not in use, so be sure to charge your batteries before you need them if you haven’t used them in a while.
  • Page 22: Maintenance

    MAINTENANCE:...
  • Page 23 Your Boston Digital Arm requires little maintenance. Once you’ve been successfully fit, the system won’t need to be adjusted often. Due to changes in your body and socket, you will probably need to visit your prosthetist for an adjustment every six months or so to ensure you’re making the correct myoelectric connection to your Digital Arm.
  • Page 24: Warnings

    Warnings Never allow your Digital Arm to be immersed in water. If your prosthesis does become immersed in water, power it down and remove it immediately and contact your prosthetist. Your Boston Digital Arm system does not require any additional lubrication.

  • Page 28: System Difficulties

    IF THE SYSTEM IS DIFFICULT TO CONTROL Make sure you are properly aligned in your socket/prosthesis Check to make sure the Free Swing lock is engaged (pulled toward you) Make sure your socket is not too loose. Weight loss can affect your connection with the electrodes in your socket, so make sure your electrodes are leaving a slight imprint on your skin for a proper connection.
  • Page 29: Low Battery Warning

    LOW BATTERY WARNINGS • A single “beep” may occur during elbow operation, usually during elbow flexion. This indicates that the battery is getting low and should be immediately recharged or replaced with a charged battery. Continued operation with a low or discharged battery can result in hyper-extension or hyper-flexion which can damage the elbow.
