[. . . ] M Getting Started Microsoft® Pointing Devices www. microsoft. com/mouse Health Warning Use of a keyboard or pointing device may be linked to serious injuries or disorders. When using a computer, as with many activities, you may experience occasional discomfort in your hands, arms, shoulders, neck, or other parts of your body. However, if you experience symptoms such as persistent or recurring discomfort, pain, throbbing, aching, tingling, numbness, burning sensation, or stiffness, DO NOT IGNORE THESE WARNING SIGNS. PROMPTLY SEE A QUALIFIED HEALTH PROFESSIONAL, even if symptoms occur when you are not working at your computer. [. . . ] Consider the following types of low forces: · Dynamic force, or a force that you exert through movement. For example, pressing the keys while typing or clicking the mouse buttons. · Static force, or a force that you maintain for a period of time. For example, holding your mouse or cradling the phone. · Contact force, or pressure that occurs when you rest on an edge or hard surface. For example, resting your wrists on the edge of your desk. Consider the following suggestions to reduce the effects of low forces on your body: · Type with a light touch, keeping your hands and fingers relaxed, as it takes little effort to activate keyboard keys. Also, use a light touch when clicking a mouse button or when using a joystick or other gaming controller. · Avoid resting your palms or wrists on any type of surface while typing. The palm rest, if provided, should only be used during breaks from typing. · Relax your arms and hands when you are not typing. Do not rest on edges, such as the edge of your desk. · Hold the mouse with a relaxed hand. · Adjust your chair so the seat does not press into the back of your knees. 7 Take Breaks Taking breaks can go a long way in helping your body recover from any activity and may help you avoid MSDs. The length and frequency of breaks that are right for you depend on the type of work you are doing. Stopping the activity and relaxing is one way to take a break, but there are other ways, also. For instance, just changing tasks--perhaps from sitting while typing to standing while talking on the phone can help some muscles relax while others remain productive. To vary your daily activities and to work productively, consider the following: · Plan your work and play so that one activity is not performed for extended periods of time. · Use different input devices, such as your mouse and keyboard, to accomplish the same task. For example, to perform a scrolling task, you can use the wheel on the mouse or the arrow keys on the keyboard. · Work more efficiently by using software and hardware features to reduce your effort and increase your productivity. For example, you can press the Windows® logo key to open the Start menu. [. . . ] The term "Hardware Device" means the enclosed Microsoft Hardware Device.
