Working in Comfort with Your HP
Pavilion PC
Thank you for selecting HP computing equipment.
To optimize your comfort and productivity, it is
important that you set up your work area correctly
and use your HP equipment properly. With that in
mind, we have developed some setup and use
recommendations for you to follow, based on
established ergonomic principles.
Improper and prolonged use of keyboards and input
devices are among those tasks that have been
associated with repetitive strain injury (RSI) to soft
tissues in the hands and arms. If you experience
discomfort or pain while using any computing
equipment, discontinue use immediately and consult
your physician as soon as possible. For more
information on RSI, you may wish to consult About
Repetitive Strain Injury on page 4.
Please study the recommendations offered here and
consult the Information Sources listed on page 24.
Included there are references to relevant parts of
international standards, regulations, and guidelines,
such as ISO 9241 and the European Community
Display Screen Equipment directive. You may also
wish to consult your employers human resources
department or other relevant departments for
guidance specific to your company. For a quick
summary of the recommendations, refer to the
Comfort and Safety Checklist on page 21.
Note that the recommendations and quoted
dimensions in this guide are designed to
accommodate a broad range of people. If you fall
outside this range, you may need to adapt the
recommendations accordingly. For example, if you
are very tall, your work surface may need to be
higher than indicated in this guide.

Thank you, again, for choosing HP computing
equipment.
About Repetitive Strain Injury
Because your comfort and safety are our primary
concern, we strongly recommend that you use HP
computing equipment in accordance with established
ergonomic principles and recommendations.
Scientific literature suggests that there may be a
relationship between injury to soft tissues
especially in the hands and arms and prolonged
improper use of keyboards or other equipment
requiring repeated motions of the hands and
forearms. This literature also suggests that there are
many other risk factors that may increase the chance
of such injury, commonly called Repetitive Strain
Injury.
What is RSI?
Repetitive Strain Injury (RSI also known as
cumulative trauma disorder or repetitive motion
injury) is a type of injury where soft tissues in the
body, such as muscles, nerves, or tendons, become
irritated or inflamed. RSI has been a reported
problem for those who perform repetitive tasks such
as assembly line work, meatpacking, sewing, playing
musical instruments, and computer work. RSI also
has been observed in those who frequently engage in
activities such as carpentry, knitting, housework,
gardening, tennis, windsurfing, and lifting children.

What causes RSI?
What can I do to avoid RSI?
The specific causes of RSI have not been established.
Nevertheless, the incidence of RSI has been
associated with a variety of risk factors, including:
Too many uninterrupted repetitions of an activity
•
or motion.
Performing an activity in an awkward or
•
unnatural posture.
Maintaining static posture for prolonged periods.
•
Failing to take frequent short breaks.
•
Other environmental and psychosocial factors.
•
In addition, there have been reports associating the
occurrence of RSI with the use of computer
keyboards, mice, and other input devices. Also,
certain medical conditions, such as rheumatoid
arthritis, obesity and diabetes, may predispose some
people to this type of injury.
Some people who use computers may experience
physical discomfort during their use. This discomfort
may be a symptom of a repetitive strain injury.
Properly setting up and using computing equipment
can help to minimize your chances of experiencing
this discomfort. Well-designed and properly adjusted
equipment alone may not be sufficient to eliminate
all potential problems. Maintaining good posture and
positioning when working on computers also has a
significant bearing on your comfort.
What if I experience discomfort?
If you are experiencing any discomfort, seek
professional medical advice immediately. Typically,
the earlier a problem is diagnosed and treated, the
easier it is to resolve.

Preparing Your Work Environment
Your Workspace
When using HP computing equipment, its important
that your work environment contribute to your
comfort and productivity. To help you achieve the
proper environment, we have developed
recommendations for optimizing your workspace,
seating, work surface, and lighting arrangements.
You, or both you and your employer, can best
determine your specific needs.
GettingStarted
6
Sufficient workspace should be available to allow
you to set up your equipment in a convenient,
comfortable arrangement.
•
The work environment should be as quiet and
free of distraction as possible.
•
For better eye comfort, you should avoid
reflective coverings on the ceiling, walls, and
floor as well as excessive contrast between the
screen and its surroundings.
As with any indoor environment, your workspace
•
should be well ventilated. If possible, adjust the
temperature to whatever is comfortable for you.
If you cant adjust the temperature, wear
appropriate clothing. Try to avoid working close
to air-conditioning or heater vents.
To prevent muscle stiffness, you must have
•
enough space to move around and vary your
position. Try not to remain in one position for
extended periods of time.
Your Chai r
Its very important that your chair provides a
comfortable sitting position and offers the following
features:
A stable base, such as five legs with casters.
•
Make sure the casters are designed for the type
of floor you have in your workspace, whether it is
bare or carpeted.
Chapter1•PreparingtoUseYourComputer
7
•
A height- and tilt-adjustment feature. It should
be easy to adjust your chair height from 40 cm
to 52 cm (15.5 inches to 20.5 inches) as measured
from the top of the seat pan to the floor. If you
are much taller or shorter than average, you may
need a chair that can be adjusted beyond this
range. Adjust your chair so that the work surface
or keyboard tray is at elbow height and your feet
are flat on the floor with your knees slightly bent
below your hips. Ideally, the seat pan should be
able to tilt both forward (minimum of 5 degrees)
and backward (minimum of 10 degrees). If the
chair has an adjustable seat pan, inclining the
seat slightly forward will transfer some of the
pressure from the spine to the thighs and feet.
This will relieve pressure on your back.
•
A curved seat edge. The front of the seat should
be curved and finished in a waterfall edge.
•
An adjustable back support in both height and
forward and backward tilt. It is important that the
backrest correctly supports the lower part, or
lumbar curve, of the back.
•
A freely rotating swivel so you can move easily
from side-to-side.
•
Fully adjustable and padded armrests. The
chair arms should not interfere with adjusting the
chair or moving it close to your work surface.
GettingStarted

Your Work Surface
Ideally, you should be able to adjust the height of
your work surface.
A simple way to ensure your work surface is at the
correct height is to first adjust the height of the seatpan of your chair. With your chair properly adjusted
and your feet firmly on the floor, adjust the work
surface height until your forearms are parallel to the
floor when you have your fingers on the keyboard or
other input device.
If possible, choose a work surface with cable
management capabilities. This will keep your cables
and wires orderly, off the floor and out of your way.
Its also best to choose a non-reflective work surface
to minimize eye discomfort from reflections and
glare.
Chapter1•PreparingtoUseYourComputer

Lighting
Work Environment Specifications
•
For better eye comfort in your work environment,
you should avoid reflective surface coverings.
The ceiling, walls, and floors should have a
medium level of reflectance (approximately
75 percent, 40 percent, and 30 percent,
respectively). Try to avoid excessive contrast
between the screen and its surroundings.
Proper lighting can help you avoid eye discomfort.
Lighting in your area should allow easy reading of
documents and keyboard legends. If more light is
needed for a particular task, use individual task
lighting rather than increasing the general lighting.
Incoming light should be shielded or diffused to
prevent glare and reflection. In cases where strong
sunlight is a problem, curtains, adjustable shades,
anti-glare filters, or monitor hoods are possible
solutions.
GettingStarted

•
The work environment should be as quiet and
free of distraction as possible, with background
noise below 55 dBA.
•
Where possible, relative air humidity should be in
the range of 40 to 60 percent.
•
The recommendation for room temperature is
19 to 23 degrees C (66 to 73 degrees F). The
workplace should be well ventilated, as with any
indoor environment.
Recommended work surface space is 160 cm
•
wide by 80 to 90 cm deep (63 inches by 32 to
36 inches deep), or a corner unit of 91 to 107 cm
deep (36 to 42 inches). The recommended
vertical adjustment range is 66 to 77 cm (26 to
30 inches). If the height is fixed, it should be
between 72 and 75 cm (28.5 to 29.5 inches).
There should be at least 6 cm (2 inches) between
•
your thighs and the work surface. If the surface
has a kneehole, it should be at least 58 cm
(23 inches) wide, 65 cm (25.5 inches) high, and
60 cm (24 inches) deep.
Recommended lighting levels are between
•
300 and 500 lux (30 to 50 foot-candles). Values
over 1000 lux (100 foot-candles) are considered
to be too bright. For work on the screen, 300 lux
(30 foot-candles) is enough for most work.
When documents are to be read, 500 lux
(50 foot-candles) is recommended.
Your Work Posture
Sitting in one position for long periods can be
uncomfortable. To minimize the potential for
physical discomfort or injury, its important that you
maintain proper posture.
Chapter1•PreparingtoUseYourComputer
11
•
Back While sitting at your work surface, make
sure your back is supported by the chairs
backrest in an erect position or angled slightly
backwards.
•
Arms Your arms should be relaxed and loose,
elbows close to your sides, with forearms and
hands approximately parallel to the floor.
•
Wrists Your wrists should be as straight as
possible while using the keyboard, mouse, or
trackball. They should not be bent sideways, or
more than 10 degrees up or down.
•
Legs Your thighs should be horizontal or
angled slightly downward. Your lower legs
should be near a right angle to your thighs. Your
feet should rest flat on the floor. If necessary, use
a footrest, but double check that you have your
seat height adjusted correctly before getting a
footrest.
•
Head Your head should be upright or tilted
slightly forward. Avoid working with your head or
trunk twisted.
•
Overall Change your position frequently and
take regular breaks to avoid fatigue.

Setting Up Your HP Computing
Equipment
Make sure that all the elements of your HP computer
system monitor, document holder, keyboard,
mice and other input devices, and headphones and
speakers are optimally arranged and adjusted to
meet your personal requirements. The recommendations that follow will help you achieve this.
Note that these recommendations apply only to the
use of HP desktop computers or HP notebook
computers that are used with a full-size keyboard,
monitor and mouse.
Your HP Monito r
It is important that your monitor screen be clean and
positioned correctly to improve readability and help
you work comfortably. Glare, high contrast,
reflections, dirt, and dust will interfere with what you
see on the screen. The recommendations that follow
can help you achieve a comfortable arrangement.
Chapter1•PreparingtoUseYourComputer
13
•
The top of your monitor screen should be at or
slightly below eye level. Most HP monitors come
with a tilt-and-swivel feature that makes it easy to
adjust the screen position. If your monitor doesnt
have this feature, consider acquiring an accessory
that provides this capability.
•
To avoid obscuring your view, the screen should
be positioned perpendicular to your line of sight;
that is, straight on.
•
To avoid glare or reflection, try to position the
monitor so the screen is at a right angle to your
window rather than in front of it. If reflection or
glare persists, tilting the screen forward may
help. If this adjustment is not sufficient, it may be
necessary to change either the position of the
monitor on your work surface, or the location of
your work surface. If reflection or glare is still a
problem, find out where it is coming from.
Common sources of glare are overhead lights,
windows, or reflections from shiny surfaces
including pictures or even bright clothing. See if
there is a way to control the source of the
problem (see Lighting on page 10). If that
doesnt work, try a high-quality anti-glare filter or
a screen hood.
•
Maintain a comfortable viewing distance to the
screen. Most people prefer a viewing distance of
approximately 46 to 76 cm (18 to 30 inches),
depending on monitor size. Character size and
the amount of space available on the work
surface can affect this distance.

GettingStarted
Text should be easy to read. To help ease
•
eyestrain, adjust text attributes such as character
size, spacing, and color. In addition, you will need
to use the controls provided with your monitor to
adjust the visual settings so that contrast and
brightness levels are comfortable for you. High
contrast and low brightness is usually the
preferable combination.
image on your screen is not stable, the monitor
may require repair or adjustment.
When possible, use a program that has a simple
•
user interface, such as easily identifiable icons
and pull-down menus. Also, screen information
should be displayed in a structured and wellorganized way.
Monitor use specifications
When viewing your monitor, your head should
•
not be tilted more than 15 degrees forward.
Optimum readability for monitor use is generally
•
considered to be 21 minutes of arc. This
corresponds to a character size of 3.7 mm
(0.15 inches) at a viewing distance of 60 cm
(24 inches).
You should not have to look up more than
•
5 degrees above horizontal or down more than
30 degrees below horizontal for normal work
tasks, such as typing or reading.
Chapter1•PreparingtoUseYourComputer
15
Document Holders
When keying in data from a hard-copy document,
placing it in a document holder rather than on a flat
surface will make it easier to read. The following
recommendations should be observed when using a
document holder:
•
The document holder should be at
approximately the same height and distance
from your eyes as the screen, and as close to the
monitor as possible to prevent neck twisting.
Some users prefer a document holder mounted
to the monitor, while others prefer the document
holder positioned between the screen and
keyboard.
•
If the primary task is to view documents rather
than using the monitor, the document holder
may be placed directly in front of the keyboard
with the monitor slightly to the side.
•
To help reduce stress on your neck and prevent
eye fatigue, try to minimize the movement of
your head and eyes while using a document
holder.
16
GettingStarted
Your HP Keyboard
The proper positioning and use of your HP keyboard
is important when using HP computing equipment.
Be sure to observe the following recommendations to
optimize your comfort and safety:
We recommend you place your keyboard in front
•
of the screen or document holder, whichever is
viewed the most. Your HP keyboard has long
cables, so you can place it in the position that is
most comfortable for you while you are using
your system.
Because HP keyboards vary in depth, youll want
•
to be sure that your work surface or keyboard
tray has sufficient room to accommodate your
model. The keyboard tray should be wide
enough to hold both the keyboard and mouse or
trackball: 66 to 71 cm (26 to 28 inches).
Your HP keyboard may have a kickstand that can
•
be opened or closed to raise or lower the
keyboard angle. If you are in the correct sitting
position with your elbows at about the same level
as the work surface, you may not need to use it.
However, if your elbows are below the work
surface, you may wish to use the kickstand to
raise the back of the keyboard.
Chapter1•PreparingtoUseYourComputer
17
•
An adjustable keyboard tray may be useful if you
cannot adjust your chair or work surface to the
proper height for typing. It should adjust in
height from 64 to 76 cm (25 to 30 inches) above
the floor and tilt forward and backward to help
you find the most comfortable position. Note
that research has shown that there may be less
muscle tension in shoulders and forearms with
the keyboard tilted away from you.
•
When using your HP keyboard, remember it takes
very little pressure or force from your fingers to
activate the keys. Improper typing style the
use of too much force can place unnecessary
stress on the tendons and muscles in your hands,
wrists, and forearms.
•
Make sure that your hands are in a neutral
position when you use your keyboard. This
means that your forearms, wrists, and hands
should be in a straight line.
•
The keyboard has a low profile to help prevent
excessive bending of your wrists while typing.
Literature suggests that you should not bend
your wrists sideways or more than 10 degrees up
or down. Keep your wrists straight by moving
your entire hand and forearm over to use the
function keys or numeric keypad.
•
You may use a palm rest to help keep your hands
and wrists in a comfortable and neutral position
when you are not typing. Some HP keyboards
come with an integrated palm rest. If you use a
palm rest, see that it is rounded and padded, and
flush in height with the front edge of the
keyboard. Note that your palms not your
wrists should rest on the palm rest. If you
dont have a palm rest, try not to rest your wrists
on a sharp edge, such as a work surface edge.
18
GettingStarted
Mice and Other Input Devices
Various aspects of using mice and other input devices
may increase your risk of discomfort or injury.
Observing the following recommendations may
reduce that risk:
As with the keyboard, try to keep your hand,
•
wrist, and forearm in a neutral position while
using your mouse or other input device.
When using a stylus or light pen with a graphics
•
tablet, dont grip the stylus tightly. Keep your
hand and fingers relaxed and try to maintain a
neutral posture in your hand, wrist, and forearm.
If you use your thumb to rotate the ball on a
•
trackball or spaceball, keep it in a relaxed,
natural shape, and maintain a neutral posture in
your hand, wrist, and forearm.
Hold the mouse gently by draping your fingers
•
over it. Keep your hand relaxed and fingers
loose. Do not grip the mouse tightly.
It takes very little pressure or force from your
•
fingers to activate the buttons or scroll wheel on
your mouse, scrolling mouse, trackball, or other
input device. Using too much force can place
unnecessary stress on the tendons and muscles
in your hands, wrists, and forearms.
If you are using a scrolling mouse, be sure to
•
keep your fingers and hand in a relaxed, neutral
position when activating the scroll wheel. Also,
this type of mouse features software that can
minimize the number of mouse movements or
button clicks.
Chapter1•PreparingtoUseYourComputer
19
•
When using a mouse, trackball, stylus and
graphics tablet, or other input device, position it
as close to the keyboard as possible, and keep it
at the same level so you do not have to stretch
while using it.
•
Use a good quality mouse pad to enable the
mouse to work most effectively and reduce
unnecessary hand and wrist movements.
Headphones and Speakers
•
Be sure to keep your mouse and trackball clean.
Regular removal of accumulated dust and dirt
helps ensure proper tracking and reduces
unnecessary hand and wrist motions.

Listening to loud sounds for prolonged periods may
permanently damage your hearing. To avoid
discomfort from unexpected noise, always turn down
the volume before connecting headphones or
speakers to your HP equipment.
When you put on the headphones, slowly increase
the volume until you find a comfortable listening
level, then leave the volume control in that position.
