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.

wash basins, bathtubs, shower stalls, and so on.

Be sure that you always do the following:

n Keep your Macintosh away from sources of liquids, such as

as rain, snow, and so on.

n Protect your Macintosh from dampness or wet weather, such

n Read all the installation instructions carefully before you plug

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

to accommodate your physical size and shape.

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.

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

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.
