To BeginBegin

This chapter explains how to set up your computer, gives you tips on working comfortably, and takes you on a tour of the computer’s features.

Making sure you have everything

Before you do anything else, consult the Quick Start card (packed at the top of the box) to make sure you received everything.
If any items are missing or damaged, notify your network administrator.

Selecting a place to work

Your Tecra 8000 Series computer is portable, designed to be used in a variety of circumstances and locations. However, by giving some thought to your work environment, you can protect the computer and work in comfort
.
1
To Begin
2
Selecting a place to work
Keeping the computer comfortable
Place the computer on a flat surface that is large enough for the computer and any other items you need to use, such as a printer. Leave enough space around the computer and other equipment to give adequate ventilation; otherwise, they may overheat.
Make sure your work area is free from:
Dust, moisture, and direct sunlight.
Liquids and corrosive chemicals.
CAUTION: If you spill liquid into the computer, turn off the computer, unplug it from the AC power source, and let it dry out completely before turning it on again.
If the computer does not operate correctly after you turn it back on, contact your network administrator.
Equipment that generates a strong electromagnetic field, such
as large stereo speakers (other than speakers that are connected to the computer) or speakerphones.
Extreme heat, cold, or humidity. Operate the computer within
a temperature range of 41 degrees to 95 degrees Fahrenheit (5 degrees to 35 degrees Celsius) and 20 percent to 80 percent non-condensing humidity.
Rapid changes in temperature or humidity.
Sources of temperature change such as air conditioner vents
or heaters.
Part I: Getting to Know Your Computer
Keeping yourself comfortable
WARNING: Using the computer keyboard incorrectly can result in discomfort and possible injury. If your hands, wrists, and/or arms hurt while typing, stop using the computer and rest. If the discomfort persists, consult a physician.
This section provides hints on avoiding strain and stress injuries. For more information, consult books on ergonomics, repetitive­motion injury, and repetitive-stress syndrome.
Placement of the computer
Proper placement of the computer and external devices is important to avoid stress-related injuries. Consider the following when placing your computer.
To Begin
Selecting a place to work
3
Place the computer on a flat surface at a comfortable height
and distance.
You should be able to type without twisting your torso or neck
and look at the screen without slouching.
If you use an external monitor, the top of the screen should be
no higher than eye level.
If you use a paper holder, set it at the same height and distance
as the screen.
Seating and posture
When using the computer, maintain good posture with your body relaxed and your weight distributed evenly.
Proper seating is a primary factor in reducing work strain. Some people find a backless chair more comfortable than a conventional
Part I: Getting to Know Your Computer

To Begin
Selecting a place to work
chair. Whichever type you choose, use the following guidelines to adjust your chair for maximum computing comfort.
Below eye level
Approximately 90° angles
Footrest
Correct posture and positioning of the computer
Position your chair so that the keyboard is at or slightly below
the level of your elbow. You should be able to type with your shoulders relaxed and your forearms parallel to the floor.
If you are using a conventional chair:
Your knees should be slightly higher than your hips. If
necessary, use a footrest to raise the level of your knees and ease the pressure on the back of your thighs.
Adjust the back of your chair so that it supports the lower
curve of your spine. If necessary, use a cushion to provide extra back support. Lower-back support cushions are available at many office supply stores.
Sit with your back straight so that your knees, hips, and
elbows form approximately 90-degree angles when you work. Do not slump forward or lean back too far.
Lighting
Proper lighting can improve the readability of the display and reduce eyestrain.
Part I: Getting to Know Your Computer
To Begin
Selecting a place to work
Position the display panel or external monitor so that sunlight
or bright indoor lighting does not reflect off the screen. Use tinted windows or shades to reduce glare.
Avoid placing your computer in front of a bright light that
shines directly into your eyes.
If possible, use soft, indirect lighting in your computer work
area.
5
Arms and wrists
Avoid bending, arching, or twisting your wrists. Keep them in
a relaxed, neutral position while typing.
Exercise your hands, wrists, and arms to improve circulation.
Work habits
The key to avoiding discomfort or injury from strain is to vary your activities. If possible, schedule a variety of tasks into your working day. Finding ways to break up the routine can reduce stress and improve your efficiency.
Take frequent, short breaks to change position, stretch your
muscles, and relieve your eyes. A break of two or three minutes every half hour is more effective than a long break after several hours.
Avoid performing repetitive activities for long periods.
Intersperse such activities with other tasks.
Focusing your eyes on your computer screen for long periods
can cause eyestrain. Look away from the computer frequently and focus your eyes on a distant object for at least 30 seconds.
