70 AlphaSmart 3000 Maintenance and Safety Guidelines
Although a matter of some debate, there are studies that suggest the
following may be responsible for certain physical injuries: Typing for
extended periods, improper positioning of your body while using a
computing device, poor work habits, and/or individual health
problems. Physical injuries could include carpal tunnel syndrome,
tendonitis, and tenosynovitis. The warning signs of these injuries often
occur after some injury has been suffered.
The following may be symptomatic of this type of physical injury:
• Lack of feeling in the area
• A hot, burning feeling inside the area
• Tingling
• Throbbing
• Stiffness and/or aching
In particular, watch for these symptoms in the hands, wrists, arms or
neck. These symptoms may not occur during your use of the
AlphaSmart 3000, or occur during times when work has not been
performed for some time. In the event that these symptoms occur or
you experience any other physical difficulties (including pain, stiffness
or aching) that you think may be related, you should contact your
doctor promptly.
Caution: Please note that there may be a risk of physical injury due to
improper use of your AlphaSmart 3000. In order to help reduce this risk
of physical injury, read and follow the instructions in this section.
The remainder of this section provides further safety information and
advice about setting up your workstation, using proper posture, and
