thing out of the box. Now you may be asking yourself, “OK, what
do I do?” Well, 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.
Make Sure You Have Everything
Your Portégé 650CT computer comes with everything you need
to get up and running quickly. However, before you rush off, it's a
good idea to make sure you received everything you were sup-
posed to. This information is listed on the Quick Start Card at the

If any items are missing or damaged, notify your dealer immedi-
ately. For additional help, contact Toshiba as described in “If You

Select a Place to Work
Your Portégé 650CT is a portable computer, designed to be used
in a variety of circumstances and locations. However, by giving
some thought to your work environment, you can protect the com-
puter and make your work hours more comfortable.
Keep the Computer Comfortable
Use a flat surface with enough room to operate comfortably. If
you're planning to use a printer or other external device, make sure
there's enough space for it as well.
To keep your computer in prime operating condition, make sure
your work area is free from:
❖dust, moisture and direct sunlight.
❖liquids and corrosive chemicals.
Don’t spill liquids into the computer. If you spill a liquid into
the keyboard, turn the computer off, unplug it from the AC
power source, and let it dry completely before turning it on
again.
If the computer does not operate correctly after you turn it
back on, contact a Toshiba authorized service provider.
❖objects that generate a strong electromagnetic field, such as
stereo speakers or speakerphones.
❖rapid changes in temperature or humidity and sources of tem-
perature changes such as air conditioner vents or heaters.
❖extreme heat, cold or humidity. Operate the computer within a
temperature range of 40 to 95 degrees Fahrenheit (5 to 35
degrees Celsius) and a relative humidity of 20 to 80 percent.

Keep Yourself Comfortable
Strain and stress injuries are becoming more common as people
spend more time using their computers. However, with a little care
and proper use of the equipment, you can work comfortably
throughout the day.
Using the computer keyboard incorrectly can result in dis-
comfort and possible injury. If your hands, wrists, and/or
arms bother you while typing, discontinue using the com-
puter and rest. If discomfort persists, consult a physician.
In addition to the hints provided in the following sections, there
are a number of books available on ergonomics, repetitive strain
injury, and repetitive stress syndrome.
Placement of the Computer
Proper placement of the computer and external devices is impor-
tant to avoid stress-related injuries:
❖Place the computer on a flat surface at a comfortable height
and distance. Your arms and hands should be in a relaxed posi-
tion with your forearms parallel to the floor. The top of the
LCD display should be no higher than eye level.
❖Maintain good posture with your body relaxed and your
weight distributed evenly. You should be able to type without
twisting your torso or neck, and see the display panel without
slouching.
❖Adjust the display panel to avoid glare.
❖Adjust the angle of the computer’s keyboard by unfolding the
keyboard legs.
❖If you use a paper holder, set it at about the same height and
distance as the computer.

Seating and Posture
Proper seating is one of the primary factors in reducing work
strain. Some people find an ergonomic (backless) chair more com-
fortable than a conventional chair. Whichever type you choose,
refer to the following guidelines to adjust your chair for maximum
computing comfort.
Correct posture and positioning of the computer
❖Position your chair so the keyboard is at or slightly below the
level of your elbow. You should be able to type comfortably
with your shoulders relaxed.
If you are using a conventional chair:
❖Your knees should be slightly higher than your hips. If neces-
sary, use a foot rest to raise the level of your knees and ease the
pressure on the back of your thighs.
❖Adjust the back of your chair so 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 legibility of the display and
reduce eye strain.
❖Position the display panel 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
could shine directly in your eyes.
❖If possible, use soft, indirect lighting in your computer work
area.
Arms and Wrists
❖Avoid bending, arching, or angling 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 repetitive strain is
to vary your activities. If possible, schedule a variety of tasks into
your work day. Finding ways to break up the routine can reduce
stress and improve your efficiency.
❖Take frequent breaks to change position, stretch your muscles,
and relieve your eyes.
❖Avoid performing repetitive activities for prolonged periods of
time. Vary activities from one task to another.
❖Focusing your eyes on your computer screen for long periods
of time can cause eye strain. Look away from the computer
frequently and focus your eyes on a distant object.
