SAFETY AND REGULATORY NOTICES
General
Electrical
The computer uses a safety ground and must be earthed.
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.
i
SAFETY & REGULATORY NOTICES
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.
ii
Maintenance
Transporting
SAFETY & REGULATORY NOTICES
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.
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.

You should read this chapter even if you do not read any other. It
provides important information to help you to use your
Apricot server safely and efficiently.
Turning on the PC
To turn on the computer, simply press the P
colour of the Power Mode indicator turns from [red] to [green].
Remember that the monitor has its own power button or switch; see
the monitor’s User Guide for details.
Power-on self-test (POST)
Whenever the computer is turned on, a power-on self-test (POST)
routine tests various hardware components, and compares the actual
configuration of the computer with that recorded in its permanent
memory. During this time, BIOS sign-on and POST messages may
be displayed. These messages are not significant unless they report
errors – see the BIOS Setup & POST chapter.
Booting the operating system
Provided that POST succeeds without discovering any serious errors
or configuration discrepancies, the computer attempts to find an
operating system; that is, it attempts to ‘boot’.
Apricot PCs are typically supplied with either Windows 95,
Windows NT or MS-DOS/Windows for Workgroups already in
place or ‘pre-installed’ on the hard disk, so that the operating system
is ready for you when you turn on the computer.
NOTE
If a diskette is in the diskette drive when the computer is turned on, the
computer will attempt to boot using that diskette. This will succeed only
if the diskette is a ‘system diskette’; that is, one bearing at least the
rudiments of an operating system.
