Guidelines for safe operation
The equipment described in this guide is designed and manufactured to comply with
international safety standards IEC380 (BS5850), and is intended for use only as a
desktop computer. It must not be used for other purposes. It is most important that
unpacking and installation is carried out in accordance with the instructions given in
this Guide.
In the interests of continued safe and reliable operation, observe the following
guidelines:
• Keep the machine at a room temperature of 5-35° C (41-95° Fahrenheit) and a
relative humidity of 15-90% (non-condensing).
• Avoid sudden extremes in temperature, exposure to direct sunlight, heat sources (
such as an electric fan heater) or rain.
• Make sure that the equipment is standing on a suitable rigid horizontal flat surface,
allowing enough space for air to circulate when it is in use.
• Ensure that wires and cables are routed sensibly so that they cannot be snagged or
tripped over. Don't tug or twist any wires or cables, or use them to hang or lift any
of the units.
• Keep the original packaging in case you need to transport the computer, and avoid
bumping or jarring it in transit.
• DON'T attempt to open any display or monitor unit, whether supplied with the
equipment or not.
• DON'T spill liquids on the machine. If liquid does spill, turn the machine off
immediately and take it to your supplier for assessment.
• DON'T drop the equipment or subject it to excessive bumping and jarring.
• DON'T obstruct or poke objects through the ventilation openings in the computer
casing, or cover them with anything.
• DON'T exceed a maximum power consumption of 5 watts from the expansion
port supply.
• DON'T balance any objects, or stand equipment on top of the computer, except
when using an Acorn-approved monitor stand, available from your Acorn
supplier.
For United Kingdom
users
For all users
Warning: this computer must be earthed.
Important: The wires in the mains lead for the computer are coloured in accordance
with the following code:
Green and yellow: Earth
Blue: Neutral
Brown: Live
The moulded plug must be used with the fuse and fuse carrier firmly in place. The
fuse carrier is the same basic colour (though not necessarily the same shade of that
colour) as the insert in the base of the plug. Different manufacturers' plugs and fuse
carriers are not interchangeable. In the event of loss of the fuse carrier, the moulded
plug MUST NOT be used. Either replace the moulded plug with another conventional
plug wired as described below, or obtain a replacement fuse carrier from an Acorn
Computers authorised dealer. In the event of the fuse blowing, it should be replaced,
after clearing any faults, with a 3-amp fuse that is ASTA approved to BS1362.
If the socket outlet available is not suitable for the plug supplied, first check that the
outlet is not of a different mains voltage or frequency from the computer. Provided it
is the same, either a different lead should be obtained or the plug should be cut off
and the appropriate plug fitted and wired as noted below. The moulded plug which
was cut off must be disposed of as it would be a potential shock hazard if it were to be
plugged in with the cut off end of the mains cord exposed.
As the colours of the wires may not correspond with the coloured markings
identifying the terminals in your plug, proceed as follows:
The wire which is coloured green and yellow must be connected to the terminal in the
plug which is marked by one of the following: the letter E, the safety earth symbol,
the colour green, or the colour green and yellow.
The wire which is coloured blue must be connected to the terminal which is marked
with the letter N, or coloured black.
The wire which is coloured brown must be connected to the terminal which is
marked with the letter L, or coloured red.

Welcome to the A3000 computer
The first part of this Guide introduces your new A3000 computer; it
explains how to connect it together and how to start using it.
It doesn't matter if you've never used a computer before — the A3000
system is easy to use, and you need learn only a few simple techniques
and terms to get going. You can pick up the details as you go along.
Once you've set everything up and mastered the techniques described in
this guide, the User Guide will help you to get the best out of your
A3000 system and answer many other questions you may have about
the software side of things — the operating system and the applications
supplied with your computer.
The second part of the Guide gives you some advice about looking after
your computer. It also contains some more detailed information about
the A3000 computer, which you may need to refer to when you want to
use equipment such as printers.
At the end of the Guide there is a Glossary to help you with computer
terminology that you may find unfamiliar. Terms explained in the
glossary are printed in italics the first time they appear in the Guide.
