SAFETY AND REGULATORY NOTICES

General

Electrical

The system employs a safety ground

Das System benötigt aus Sicherheitsgründen einen Masseanschluß

Le système doit être mis à la terre

Dette system bruger en sikkerhedsjordforbindelse

Apparaten skall anslutas till jordat uttag när den anslutas till ett nätverk

The system unit AC power cord is its ‘disconnect device’. Ensure that the system

unit is positioned close to the AC power outlet and that the plug is easily accessible.

The power cord packed with the computer complies with the safety standards

applicable in the country in which it is first sold. Use only this power cord. Do not

substitute a power cord from any other equipment.

To prevent fire and electric shock, do not expose any part of the computer to rain or

moisture. Turn off the computer and unplug all power cords before moving or

cleaning the system unit, or removing the system unit top cover.

Battery

This product contains a lithium battery.

Do not use a metal or other conductive implement to remove the battery. If a short-

circuit is made between its positive and negative terminals the battery may explode.

Replace a discharged battery with one of the same type; another type may explode

or ignite. Follow the instructions contained in the Owner’s Handbook to replace the

battery. Dispose of a discharged battery promptly and in accordance with the

battery manufacturer’s recommended instructions. Do not recharge, disassemble or

incinerate the discharged battery. Keep away from children.

Laser products

Any CD-ROM drive fitted in this system is classified as a CLASS 1 LASER

PRODUCT according to IEC825 Radiation Safety of Laser Products (Equipment

Classification: Requirements and User's Guide). The CLASS 1 LASER PRODUCT

label is located on the underside of the system unit.

The CD-ROM drive contains a laser system which is harmful to the eyes if exposed.

Do not attempt to disassemble the CD-ROM drive; if a fault occurs, call an

authorised maintainer.

Use the CD-ROM drive only as described in this manual. Failure to do so may

result in exposure to hazardous radiation.

Safety & Regulatory Notices

NOTICES/ii

Ergonomic

When positioning the system unit, monitor and keyboard, take into account any

local or national regulations relating to ergonomic requirements.

Anti-static precautions

Warning

Static electricity can cause permanent damage to electronic components. You

should be aware of this risk, and take precautions against the discharge of static

electricity into the computer.

The computer is at risk from static discharge while the top cover is off. This is

because the electronic components of the motherboard are exposed. Memory

modules, expansion cards and replacement processors are examples of electrostatic

sensitive devices (ESSDs).

All work that involves removing the cover must be done in an area completely free

of static electricity. We recommend using a Special Handling Area (SHA) as defined

by EN 100015-1: 1992. This means that working surfaces, floor coverings and

chairs must be connected to a common earth reference point, and you should wear

an earthed wrist strap and anti-static clothing. It is also a good idea to use an ionizer

or humidifier to remove static from the air.

When installing any upgrade, be sure you understand what the installation

procedure involves before you start. This will enable you to plan your work, and so

minimise the amount of time that sensitive components are exposed.

Do not remove the system unit cover, nor the anti-static bag or wrapping of any

upgrade, until you need to.

Handle static-sensitive items with extreme care. Hold expansion cards and add-on

components only by their edges, avoiding their electrical contacts. Never touch the

components or electrical contacts on the motherboard or on expansion cards. In

general, do not handle static-sensitive items unnecessarily.

Keep all conductive material, and food and drink, away from your work area and the

open computer.

Thermalcote bonding compound

The thermal bonding compound used between the system processor and its heat

sink can cause skin irritation and stain clothing. Avoid prolonged or repeated

contact with skin. Wash thoroughly with soap and water after handling. Avoid

contact with eyes and inhalation of fumes. Do not ingest.

Safety & Regulatory Notices

NOTICES/iii

Maintenance

Switch off and disconnect all cables before attempting to clean the computer.

Do not use sprays, solvents or abrasives that might damage the system unit surface.

Do not use cleaning fluids or sprays near air vents, ports, or the diskette and CD-

ROM drives.

Occasionally wipe the system unit with a soft, slightly damp, lint-free cloth.

Occasionally wipe over the air vents on the rear and sides of the system unit. Dust

and fluff can block the vents and limit the airflow.

Occasionally clean the diskette and CD-ROM drives using a proprietary head

cleaner.

Occasionally wipe the monitor with a soft, slightly damp, lint-free cloth. It is best to

use anti-static glass cleaner on the monitor screen, but do not spray glass cleaner

directly onto the screen; it could run down inside the case and damage the circuitry.

Transporting

Use common sense when handling the computer; hard disks in particular can be

damaged if the computer is dropped or handled roughly. As a precaution, back up

the contents of the hard disks to tape or diskettes before moving the computer.

Switch off and disconnect all cables before attempting to move the computer,

particularly do not try to move the computer while it is plugged into the AC power

supply.

When lifting and carrying the computer, use the metal sides of the system unit and

never attempt to lift the system unit with a monitor still on top.

If you need to transport the computer any great distance, use the original packing

materials.

If you are planning to use the computer in another country, it may not be suitable,

check with your supplier, particularly on the availability of the correct AC power

cords.

Note

Any existing maintenance or warranty agreement may not be supportable in another

country. The system may have to be returned to the supplier.
