Comfort and Safety Checklist
• If you are using a scrolling mouse, be sure to keep your fingers and hand in a
relaxed, neutral position when activating the scroll wheel. Also, this type of mouse
features software that can minimize the number of mouse movements or button
clicks.
• When using a mouse, trackball, stylus and graphics tablet, or other input device,
position it as close to the keyboard as possible, and keep it at the same level so you
do not have to stretch while using it.
• Use a good quality mouse pad to enable the mouse to work most effectively and
reduce unnecessary hand and wrist movements.
• Be sure to keep your mouse and trackball clean. Regular removal of accumulated
dust and dirt helps ensure proper tracking and reduces unnecessary hand and wrist
motions.
Headphones and Speakers
Listening to loud sounds for prolonged periods may permanently damage your
hearing. To avoid discomfort from unexpected noise, always turn down the volume
before connecting headphones or speakers to your HP equipment. When you put on
the headphones, slowly increase the volume until you find a comfortable listening
level, then leave the volume control in that position.
