Comfort guide-important ergonomics Information
Whether you use a keyboard or mouse for five minutes or five hours, these suggestions help you stay comfortable and work efficiently.
Some researchers and experts said that improper workspace, incorrect body posture, and bad work habits may be related to physical discomfort and nerves, tendons, and muscle injuries. If you feel pain in your hand, wrist, arm, shoulder, neck or back, numbness, tingling, weakness, swelling, burning, convulsions or stiffness, consult a qualified health professional.
To get the most comfortable and reduce the chance of injury, follow these guidelines:
1. Make sure that your workspace is properly arranged.
- Place the keyboard and monitor directly in front of you, and place the mouse next to it.
- Place the elbows on both sides of the body.
- Adjust the height of the chair and table to make the keyboard and mouse as high as or below the elbow height.
- Place the mouse in a place that is easy to touch so that the elbow remains close to both sides of the body when you use the mouse. The Optical Mouse does not require a mouse pad. If a mouse pad is used, the mouse pad thickness must be taken into account when adjusting the height. Make your feet well supported and relax your shoulders. Place the documents required for typing close to the monitor to avoid frequent head rotation and eye viewpoint changes. You can use the document holder help.
- Place materials on the desktop according to the frequency of use:
Frequently Used-place the most commonly used materials to the nearest place.
Use occasionally-place the occasionally used materials within the length of an arm.
Rarely used-put seldom used materials further, but take convenience into account.
2. Relax your shoulders, arm, wrist and hands during work.
- Let your arms drop down for a short time, so that they can relax on the floor.

- When using a keyboard or mouse, avoid placing your wrist on a sharp edge or desktop:
- When using the mouse, make sure that the elbow is close to both sides of the body. Keep your wrist straight-do not bend up or down or toward any side. Keep your shoulders relaxed. Do not bow back or shoulders.
3. Adopt good work habits.
