Preface

Maintenance Safety Precautions

Preface

Observe safety rules when working inside the system and when handling computer components. Avoid electric shock or personal injury by observing the following warning.

Hazardous Voltage

Warning: before removing the system unit cover, turn off the power and unplug the system

power cable (and remove the main battery in portable computers). Power is removed only when the power cable is unplugged.

Electrostatic Discharge

Warning: your computer's internal components are highly susceptible to risk of damage from

electrostatic discharge (static electricity, which occurs naturally on your body due to friction). To avoid damaging your equipment, always earth yourself to your computer system before opening the computer's chassis or handling any internal component(s).

To do this, use the following procedure:

1. For best results, we strongly recommend you purchase

an anti-static wrist strap (available at electronic supply stores). To use it, connect the strap's metal “alligator clip” to an unpainted metal portion of your computer's chassis.

2. Then connect the elastic wrist band to the strap, and

slide the wrist band onto your wrist.

Note: if you do not have a wrist strap, you can earth yourself by touching (and maintaining

continuous contact with) an unpainted metal part of the computer's chassis while handling any of your computer's internal components or working inside the system.

Safety Rules

• Select a suitable work space

 Avoid carpets in cool, dry areas.  When you work on a carpet where static electricity is likely to be generated, make sure you take

anti-static measures beforehand.

• Cloth

 Do not wear a wool or synthetic cloth to work inside the computer.  Wear anti-static shoes to work inside the computer.  Take off any jewels (a ring, bracelet, or wrist watch) before working inside the computer.

• Handling of components

 Keep any component in an anti-static bag until you actually install it to the computer.  Hold a component by its edge to avoid touching any terminals or parts.

Preface

 To store or carry any component, place it in an anti-static bag.  Turn off and disconnect all peripherals.  Do not disassemble parts other than those specified in the procedure.  Label any cable connectors before disconnecting. Note where the connector goes and in what

position it was installed.

 Take care when connecting or disconnecting cables. A damaged cable can cause a short in the

electrical circuit.

 When installing a cable, route the cable so it is not pinched by other components and is out of the

path of the system unit cover.

 Prevent damage to the connectors by aligning connector pins before you connect the cable.

Misaligned connector pins can cause damage to system components at power-on.

 When disconnecting a cable, always pull on the cable connector or strain-relief loop, not on the

cable itself.

Chassis Cover Removal and Replacement

When working inside your computer, you must replace the chassis cover and secure it with the screws before plugging in the power cable and turning it on.

Preface

Setting Up a Healthy Work Environment

Preface

Warning: prolonged or improper use of a computer workstation may pose a risk of serious

injury (see "Potential Medical Conditions"). Please note that some people are more susceptible to developing these disorders due to pre-existing conditions or psychosocial factors (see "Pre-

Existing Conditions and Psychosocial Factors"). To reduce your risk of injury, set up and use

your computer in the manner described in the "Arrange Your Equipment" section. Please note that precautions can be taken in order to prevent physical discomfort (see "Reducing The Risk of

Injuries").

Potential Medical Conditions

Computers are everywhere. More and more people sit in front of computers for longer periods of time. Some nerve, tendon and muscle disorders (musculoskeletal disorders) may be associated with repetitive activities, improper work environments, and incorrect working habits. Examples of musculoskeletal disorders that may be associated with certain forms of repetitive activities include: carpal tunnel syndrome, tendinitis, tenosynovitis, de Quervain's tenosynovitis and trigger finger, as well as other nerve, tendon and muscle disorders.

Although some studies have shown an association between increasing hours of keyboard use and the development of some musculoskeletal disorders, it is still unclear whether working at a computer causes such disorders. Some doctors believe that using the keyboard and mouse may aggravate existing musculoskeletal disorders.

Note: contact a doctor if you experience pain, tenderness, swelling, burning, cramping, stiffness,

throbbing, weakness, soreness, tingling and/or numbness in the hands, wrists, arms, shoulders, neck, back and/or legs.

Repetitive Strain Injury (RSI)

Repetitive Strain Injury is caused by a constant tension of the muscles in your arms and by making the same repetitive movements with fingers, wrist and elbow when controlling the mouse. The symptoms of RSI are pain and stiffness in neck, shoulders, arms, wrists and hands. Other symptoms are cramps, tingling and exhaustion in these areas.

From Monks to Video Games Users

Repetitive Strain Injury might seem a modern age disease, caused by the increasing use of computers at work and at home, but monks already caught it in the Middle Ages. In the 16th century the Italian doctor Ramazini described the same symptoms among monks writing bibles day in day out in cold and dark rooms. In later centuries similar symptoms like knitting-, telegrapher-, hairdresser- and violin arms occurred more often. The latest versions of RSI are caused by minor movements of the thumb when operating the joystick of a game console.

Preface

The Three Stages of Repetitive Strain Injury

Real RSI-pain implies that the problems persist for a longer period of time, normally for a minimum of three months. The development can be divided into three stages:

• Stiffness, numbness, irritation, sometimes in combination with light or sharp pains. These problems

disappear, but return when similar work is done.

• The problems do not disappear overnight. Continuous light pain, also after a period of rest. After a

longer period of rest (holidays) the pain does go away, but returns easily when similar work is done.

• Continuous pain often combined with reduced strength and less accurate control. At work, the pain

intensifies. When rested, the pain remains.

Pre-Existing Conditions and Psychosocial Factors

Pre-existing conditions that may cause or make some people more susceptible to musculoskeletal disorders include the following: hereditary factors, vascular disorders, obesity, nutritional deficiencies (e.g., Vi tamin B deficiency), endocrine disorders (e.g., diabetes), hormonal imbalances, connective tissue disorders (e.g., arthritis), prior trauma (to the hands, wrists, arms, shoulders, neck, back, or legs), prior musculoskeletal disorders, aging, fluid retention due to pregnancy, poor physical conditioning, dietary habits and other conditions.

Psychosocial factors associated with these disorders include: workplace stress, poor job satisfaction, lack of support by management and/or lack of control over one's work.

Reducing The Risk of Injuries

The precautions described below can be taken in order to prevent physical discomfort.

Vary Your Workday

If you use your computer for prolonged periods, follow these instructions.

• Vary your tasks throughout the day.

• Take frequent short breaks that involve walking, standing, and stretching. During these breaks, stretch

muscles and joints that were in one position for an extended period of time (refer to "Practice Some

Stretching Exercises" below). Relax muscles and joints that were active.

• Use a timer or reminder software to remind you to take breaks.

• To enhance blood circulation, alter your sitting posture periodically and keep your hands and wrists

warm.

Practice Some Stretching Exercises

The daily exercises described below can be very effective in stopping Repetitive Strain Injury development or minimising its effects. They can easily be carried out behind your PC.

Preface

• Bend wrists, stretch and close fingers - stretch your arms and wrists with closed fingers; keep this

pose for 8 seconds. Repeat the exercise 3 times. You can repeat the same exercise with your finger stretched.

• Lift shoulders - lift your shoulders straight up, hold that pose for 8 seconds and repeat the exercise 3

times.

• Rotate shoulders - rotate both your shoulders clockwise and counter-clockwise for 8 seconds. Repeat

this exercise 3 times.

• Stretch neck and shoulders - bend your head to the left, right, front and back. Keep each position for

8 seconds. Repeat this exercise 3 times.

• Stretch the flexors - fold your hands into a praying position; palms flat against each other in front of

your chest. Pull your hands gently downwards along your chest towards the stomach, keeping the elbows in the same position. Repeat the exercise 3 times and keep the pose for 8 seconds.

• Stretch the extensors - stretch your arm straightforward. Rotate your hand 90 degrees and keep your

thumb down. Grab your hand with your other hand, and gently pull your hand towards you. Hold this pose for 8 seconds and repeat this exercise 3 times.

Arrange Your Equipment

You will find below explanations on how to set up your computer to fit your physical needs. This information is based on ergonomics - the science of making the workplace fit the needs of the worker.

Note: To increase your comfort and safety when using your notebook computer as your

primary computer system at your home or office, note the following recommendations:

• use a separate, external keyboard attached to your notebook computer

• use a separate, external monitor attached to your notebook computer.

Arrange your equipment so that you can work in a natural and relaxed position. Place items that you use frequently within easy reach. Adjust your workstation set-up to the proper height (as described below) by lowering the table or stand that holds your computer equipment or raising the seat height of your chair. Position your computer directly in front of you for increased safety and comfort.

Your Chair

Your chair should be adjustable and stable. Vary your posture throughout the day. Check the following:

• Keep your body in a relaxed yet upright position. The backrest of your

chair should support the inward curve of your back.

• Use the entire seat and backrest to support your body . Tilt the backrest

slightly (90° to 105°). The angle formed by your thighs and back should be 90° or more.

• Your seat depth should allow your lower back to comfortably contact

the backrest. Make sure that the backs of your lower legs do not press against the front of the chair.

Preface

• Extend your lower legs slightly so that the angle between your thighs and lower legs is 90° or more.

• Place your feet flat on the floor. Only use a footrest when attempts to adjust your chair and workstation

fail to keep your feet flat.

• Be sure that you have adequate clearance between the top of your thighs and the underside of your

workstation.

• Use armrests or forearm supports to support your forearms. If adjustable, the armrests or forearm

supports should initially be lowered while all the other adjustments discussed in this section are made. Once all these adjustments are completed, raise the armrests or adjust the forearm supports until they touch the forearms and allow the shoulder muscles to relax.

Yo u r De s k

There is no specific height recommended for your desk. This can vary between 60 to 70 cm, depending upon your size. The standard workaround is that it should be at approximately your elbow height.

The desktop should be clean and organized in such a way that frequently used objects are close enough without excessive reaching. If you use a document holder, it should be placed at approximately the same height as the monitor and at the same distance from the eyes to prevent frequent eye shifts.

The area underneath the desk should be clean to accommodate your legs and allow for stretching.

Your Input Devices

Note the following points when positioning your computer or any external input devices.

• Position your keyboard directly in front of you. Avoid reaching when using your keyboard or mouse.

• If you use a mouse, position it at the same height as the keyboard and next to the keyboard. Keep your

wrists straight and use your entire arm when moving a mouse. Do not grasp the mouse tightly. Grasp the mouse lightly and loosely.

• Adjust the keyboard height so that your elbows are near your body and your forearms are parallel to the

floor, with your forearms resting on either armrests or forearm supports, in the manner described previously. If you do not have armrests or forearm supports, your upper arms should hang comfortably at your sides.

• Adjust the keyboard slope so that your wrists are straight while you are typing.

• Type with your hands and wrists floating above the keyboard. Use a wrist pad only to rest your wrists

between typing. Avoid resting your wrists on sharp edges.

• Type with your wrists straight. Instead of twisting your wrists sideways to press hard-to-reach keys,

move your whole arm. Keep from bending your wrists, hands, or fingers sideways.

• Press the keys gently; do not bang them. Keep your shoulders, arms, hands and fingers relaxed.

Preface

Your Screen or Monitor

Correct placement and adjustment of the screen or external monitor can reduce eye, shoulder, and neck fatigue. Check the following when you position the screen or external monitor.

• Adjust the height of your screen or external monitor so that the top of the screen is at or slightly below

eye level. Your eyes should look slightly downward when viewing the middle of the screen or external monitor.

• Position your screen or external monitor no closer than 30 cm and no further away than 75 cm from

your eyes. The optimal distance is between 35 cm and 45 cm.

• Rest your eyes periodically by focusing on an object at least 6 metres away. Blink often.

• Position the screen or external monitor at a 90° angle to windows and other light sources to minimise

glare and reflections. Adjust the monitor tilt so that ceiling lights do not reflect on your screen or external monitor.

• If reflected light makes it hard for you to see your screen or external monitor, use an anti-glare filter.

• Clean your screen or external monitor regularly. Use a lint-free, non-abrasive cloth and a non-alcohol,

neutral, non-abrasive cleaning solution or glass cleaner to minimise dust.

• Adjust the screen or external monitor's brightness and contrast controls to enhance readability.

• Use a document holder placed close to the screen or external monitor.

• Position whatever you are looking at most of the time (the screen or reference material) directly in front

of you to minimise turning your head while you are typing.

• Get regular eye check-ups.

Your Sound Devices

Excessive sound pressure from earphones and headphones can cause hearing loss.

• Keep your computer’s sound level low.

• Get regular hearing check-ups.
