Take note of the following tips when selecting a location for your computer: · Do not put your computer near any equipment that might cause electromagnetic or radio frequency interference such as radio transmitters, televisions, copy machines, or heating and airconditioning equipment. You may place your computer beside your desk or under your table, as long as it does not block the space that you need for working and moving. · · Positioning your monitor Place your monitor at a comfortable viewing distance, usually 50 to 60 centimeters away. Adjust the display in such a way that the top of the screen is at or slightly below eye level. Positioning your keyboard The location of the keyboard is a very important factor to your posture. Placing it too far away will make your body lean forward forcing you to sit in an unnatural position. Adjust the keyboard height by flipping the folding stands located under the keyboard. If you feel any shoulder or neck strain, stop for a while and check your posture. Putting your keyboard beside your monitor will make you turn your head while you type which could add tension to your neck muscles that may later result in neck strain. · · 30 3 Setting up your computer Positioning your mouse · · · The mouse should be placed on the same surface as your keyboard so that you can reach it with ease. Adjust its position to allow enough space for movement without making you stretch or lean over. Do not rest your wrist on the table when moving the mouse. 31 Connecting peripherals Setting up your computer is easy.
