User Manual

While typing, observe whether you have a heavy or light touch. Use the minimum force needed to
depress the keys. Avoid holding unnecessary tension in your thumbs and fingers. You may be
surprised to find tension in a thumb or finger that is not being used for typing, pointing or touching.
Hold the pointing device loosely. Use your whole arm and shoulder to move the pointing device, not
just your wrist. Keep your wrist straight and your hand relaxed and click the buttons using a light
touch. To give your pointing hand a break, you may periodically control the pointing device with the
opposite hand. Use the device software to switch the button assignments. Use the software control
panel to adjust the properties of the pointing device. For example, to reduce or eliminate mouse-
lifting, try increasing the acceleration setting. When you are not using the pointing device, do not hold
on to it; let it go.
You may find that supports for your hands allow you to be more relaxed and comfortable. A palm rest
may be used to provide support during pauses, but keep your wrists free to move while typing or
using a pointing device.
