Health-related information about
computer use
Muscle soreness, eye fatigue, and other discomforts and injuries
sometimes associated with using computers can occur from
performing any number of activities. In fact, misuse of the same
muscles during multiple activities can create a problem that might
not otherwise exist. For example, if you engage in nonwork
activities that involve repetitive stress on the wrist—such as
bicycling—and also use your computer’s keyboard improperly,
you may increase your likelihood of developing wrist problems.
Some individuals are at greater risk of developing these problems
because of their health, physiology, lifestyle, and general exposure
to stress. Work organization and conditions, such as workstation
setup and lighting, also play a part in your overall health and
7
comfort. Preventing health problems is a multifaceted task that
requires careful attention to the way you use your body every
hour of every day.
The most common health effects associated with using a
computer are musculoskeletal discomfort and eye fatigue. We’ll
discuss each area of concern below. For information about electric
and magnetic emissions, look in the reference material that comes
with your computer.

as rain, snow, and so on.
n Protect your Macintosh from dampness or wet weather, such

RSIs did not suddenly arise when computers were invented;
tennis elbow and writer’s cramp, for example, are two RSIs that
have been with us for a long time. Although less common than
other RSIs, one serious RSI discussed more often today is a wrist
problem called carpal tunnel syndrome, which may be aggravated
by improper use of computer keyboards. This nerve disorder
results from excessive pressure on the median nerve as it passes
through the wrist to the hand.
This section offers advice on setting up your work area to
enhance your comfort while you use your computer. Since the
effects of repetitive movements associated with using a computer
can be compounded by those of other work and leisure activities
to produce or aggravate physical problems, proper use of your
computer system must be considered as just one element of a
healthy lifestyle.
No one, of course, can guarantee that you won’t have problems
even when you follow the most expert advice on using computer
equipment. You should always check with a qualified health
specialist if muscle, joint, or eye problems occur.
Musculoskeletal discomfort
As with any activity that involves sitting for long periods of time,
using a computer can make your muscles sore and stiff. To
minimize these effects, set up your work environment carefully,
using the guidelines that follow, and take frequent breaks to rest
tired muscles. To make working with your computer more
comfortable, allow enough space in your work area so that you
can change position frequently and maintain a relaxed posture.
Another type of musculoskeletal concern is repetitive stress
injuries (RSIs), also known as cumulative trauma disorders
(CTDs). These problems can occur when a certain muscle or
tendon is repeatedly overused and forced into an unnatural
position. The exact causes of RSIs are not totally understood, but
in addition to awkward posture, such factors as the amount of
repetition, the force used in the activity, the individual’s
physiology, workplace stress level, and lifestyle may affect the
likelihood of experiencing an RSI.

Here are some guidelines for adjusting the furniture in your office

be relaxed. Your upper arm and forearm should form an
approximate right angle, with your wrist and hand in roughly
a straight line.
You may have to raise your chair so your forearms and hands
are at the proper angle to the keyboard. If this makes it
impossible to rest your feet flat on the floor, you can use a
footrest with adjustable height and tilt to make up for any gap
between the floor and your feet. Or you may lower the
desktop to eliminate the need for a footrest. Another option is
to use a desk with a keyboard tray that’s lower than the
regular work surface.

Eye fatigue
Eye fatigue can occur whenever the eyes are focused on a nearby
object for a long time. This problem occurs because the eye
muscles must work harder to view an object that’s closer than
about 20 feet (6 meters). Improper lighting can hasten the
development of eye fatigue. Although eye fatigue is annoying,
there’s no evidence that it leads to permanent damage.
Whenever you’re engaged in an activity that involves close-up
work—such as reading a magazine, doing craft work, or using a
computer—be sure to have sufficient glare-free lighting and give
your eyes frequent rest breaks by looking up and focusing on
distant objects. Remember to have your eyes examined regularly.
To prevent discomfort and eye fatigue:

Installing an expansion card
The Macintosh comes with a slot inside called a processor-direct
slot in which you can install a processor-direct expansion card for
special purposes. Some expansion cards are designed so that you
can install them yourself. Others can be installed only by an Apple-
authorized representative. To install a card, use the
documentation supplied with the card you plan to install, or
follow the instructions in this section.
s Warning: If you have installed a floating-point unit (FPU) on
card, do not attempt to install any expansion card without
first checking the documentation for that card. If the
documentation specifies that an Apple-certified technician
must install the card (usually because the installation requires
special training or tools), consult the service and support
information that came with your computer for instructions on
how to contact an Apple-authorized service provider or Apple
for assistance. If you attempt to install the card yourself, any
your Macintosh may not work properly.

Using a RAM disk for temporary storage
For improved performance, you may want to set aside part of your
random-access memory (RAM) to use as a temporary hard disk.
Using a RAM disk improves performance because the computer
can get data from a RAM disk much faster than from a hard disk or
floppy disk.
You use a RAM disk exactly as you would use a hard disk or floppy
disk, except that you save your work onto another disk before you
shut down the computer.
To set up a RAM disk:
1. Choose Control Panels from the Apple (K) menu.
2. Open the Memory control panel.

Remember that the more RAM you allot as a RAM disk, the
less you will have available for running application programs.

Starting up your computer
from an external hard disk
To start up your Macintosh from an external hard disk, the hard
disk must contain a System Folder, and the System Folder must
contain a System Enabler for your Macintosh. (A System Enabler
file contains software necessary to start up a specific Macintosh
model.)
If you are unable to start up your Macintosh from an external disk,
the appropriate System Enabler file may be missing from that disk.
Use the Installer program on the Install Me Firstdisk that came
with your computer to install system software on the external
disk.
