HP Pavilion N3210 Setup Manual page 43

You may use a palm rest to help keep your hands and wrists in a comfortable and
neutral position when you are not typing. Some HP keyboards come with an
integrated palm rest. If you use a palm rest, see that it is rounded and padded, and
flush in height with the front edge of the keyboard. Note that your palms—not your
wrists—should rest on the palm rest. If you don't have a palm rest, try not to rest your
wrists on a sharp edge, such as a work surface edge.
Mice and Other Input Devices
Various aspects of using mice and other input devices may increase your risk of
discomfort or injury. If you connect an external mouse to your computer, observing the
following recommendations may reduce that risk.
As with the keyboard, try to keep your hand, wrist, and forearm in a neutral position
while using your mouse or other input device.
When using a stylus or light pen with a graphics tablet, don't grip the stylus tightly.
Keep your hand and fingers relaxed and try to maintain a neutral posture in your
hand, wrist and forearm.
If you use your thumb to rotate the ball on a trackball or spaceball, keep it in a
relaxed, natural shape, and maintain a neutral posture in your hand, wrist, and
forearm.
Hold the mouse gently by draping your fingers over it. Keep your hand relaxed and
fingers loose. Do not grip the mouse tightly.
It takes very little pressure or force from your fingers to activate the buttons or scroll
wheel on your mouse, scrolling mouse, trackball, or other input device. Using too
much force can place unnecessary stress on the tendons and muscles in your hands,
wrists, and forearms.
