Audio problems

Problem Solution

The audio cannot be heard on the Windows

operating system.

• If you are using powered external speakers that have an On/Off

control, ensure that:

– The On/Off control is set to the On position.

– The speaker power cable is connected to a properly grounded,

functional ac electrical outlet.

• If your external speakers have a volume control, ensure that the

volume is not set too low.

• Click the volume icon in the Windows notification area on the

taskbar. Check the speaker and volume settings. Do not mute the

speaker or set the volume at a very low level.

Ergonomic information

Good ergonomic practice is important to get the most from your personal computer and to avoid discomfort.

Arrange your workplace and the equipment you use to suit your individual needs and the kind of work that

you perform. In addition, use healthy work habits to maximize your performance and comfort when using

your computer.

Working in the virtual office might mean adapting to frequent changes in your environment. Adapting to the

surrounding light sources, active seating, and the placement of your computer hardware, can help you

improve your performance and achieve greater comfort.

This example shows someone in a conventional setting. Even when not in such a setting, you can follow

many of these tips. Develop good habits, and they will serve you well.

General posture: Make minor modifications in your working posture to deter the onset of discomfort caused

by long periods of working in the same position. Frequent short breaks from your work also help to prevent

minor discomfort associated with your working posture.

Appendix A. Accessibility and ergonomic information 63

Display: Position the display to maintain a comfortable viewing distance of 510 mm to 760 mm (20 inches to

30 inches). Avoid glare or reflections on the display from overhead lighting or outside sources of light. Keep

the display screen clean and set the brightness to levels that enable you to see the screen clearly. Press the

brightness control keys to adjust display brightness.

Head position: Keep your head and neck in a comfortable and neutral (vertical, or upright) position.

Chair: Use a chair that gives you good back support and seat height adjustment. Use chair adjustments to

best suit your comfort posture.

Arm and hand position: If available, use chair arm rests or an area on your working surface to provide

weight support for your arms. Keep your forearms, wrists, and hands in a relaxed and neutral (horizontal)

position. Type with a soft touch without pounding the keys.

Leg position: Keep your thighs parallel to the floor and your feet flat on the floor or on a footrest.
