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 shortcircuit 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.

result in exposure to hazardous radiation.
NOTICES/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.
NOTICES/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 CDROM 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.

General advice
This computer is designed to be used in a normal home or office
environment. Here are a few hints for choosing a suitable site:
Place the system unit flat on a sturdy, level surface, free from
vibration.
Site the computer away from moisture, direct sunlight, and
extremes of heat and cold. Avoid situations in which the
surrounding temperature or humidity may change rapidly.
When the computer is in use, the temperature should be
between 10 and 35
o
C and humidity between 20% and 80%
(with no condensation).
When positioning the system unit, monitor and keyboard, take
into account any local or national regulations relating to
ergonomic requirements. For example, you should ensure that
little or no light is reflected off the monitor screen as glare, and
that the keyboard is placed in a comfortable position for
typing.
Give the computer plenty of room so that air can circulate on
all sides. Air is drawn into the system unit through vents at the
front and on the left-hand side, and expelled through the vent
on the back. Ensure that these vents are never obstructed.
Do not allow any cables, particularly power cords, to trail across the
floor where people walking past can snag them.
Warning
The computer uses the system unit AC power cord as its ‘disconnect
device’. Ensure that the system unit is positioned close to the AC power
outlet, and that the plug is easily accessible.
To prevent fire and electric shock, do not expose any part of the system
unit to rain or moisture.
1/6 OWNER’S HANDBOOK
Connecting the components
Use the following guidance to connect the components together. It
is important that you take each step in the order indicated.
1. Before connecting any components, ensure that the AC power
supply is switched off or disconnected, and that the system
unit, the monitor, and any peripherals are turned off.
2. Connect the components’ signal cables to their respective ports
on the system unit: keyboard, mouse, monitor, audio (where
appropriate) and any other peripherals. Where appropriate,
connect the computer to the network.
3. Connect the components’ power cords: monitor to system
unit, and system unit and any other peripherals to nearby,
grounded AC power outlets. Then switch on or connect the
AC power supply.
With AC power applied, the system unit is usually in Off mode
[LED unlit]. See the Getting Started chapter for more information
about power modes.
Some models incorporate a feature, controlled in BIOS Setup, that
automatically boots the PC to Power Controlled [green] mode if AC
power is restored, for example, after a power failure. The PC can
also be set to wake up from Power Minimised [amber] in the event
of incoming information from a modem or from the network. See
the BIOS Setup and POST chapter for more information.
Welcome
OWNER’S HANDBOOK 1/7
Getting Started
2 GETTING STARTED
You should read this chapter even if you do not read any other. It
provides important information to help you to use your Mitsubishi
Electric CX Series computer safely and efficiently.
Turning on the PC
To turn on the computer, simply press the P
Power Mode indicator lights up [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’.
Mitsubishi Electric PCs are typically supplied with either
Windows 3.11 (Windows for Workgroups), Windows 95,
Windows 98, or Windows NT 4.0 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.

working. However, during periods of inactivity it can
automatically reduce power consumption to idle
components. For example, the monitor screen may go
blank.
If a suitable modem is installed, you can tell the computer to wake
itself up from the Power Minimised or Off state when an incoming
call is received. A networked computer can also be woken up by
remote control, if it is fitted with a network card that supports
IBM’s “Wake On LAN” technology.
Power management and Windows
Mitsubishi Electric CX Series computers support the two types of
power management that may be used by Windows operating
systems: Advanced Power Management (APM) and Advanced
Configuration & Power Interface (ACPI).

Using the computer for the first time
First time with Windows 95/98 or Windows NT
The first time you turn on your computer you must tell Windows
your name (and the name of the company for which you work, if
applicable) and agree to the legal terms and conditions of the
Windows Licence Agreement. Windows then spends a few minutes
analysing your computer and configuring itself to take full
advantage of your computer’s components. Windows 95 and
Windows 98 also offer you the opportunity to install a printer.
First time with Windows 3.11
The first time you turn on your computer a message appears
explaining the legal terms and conditions that govern the use of the
software pre-installed on the computer’s hard disk. Once you have
read this message, you can press the <F3> key to continue. By doing
so you are acknowledging that you have read, understood and
accepted the terms and conditions.
Backing-up the pre-installed software
Getting Started
We strongly recommend that you copy or ‘back-up’ the operating
system and any pre-installed software soon after setting up the
system. This is particularly important for systems that are supplied
without installation diskettes for the software on the hard disk. A
back up copy will safeguard the pre-installed software against loss if
the hard disk fails or if you accidentally overwrite or delete files.
The Microsoft Create System Disks tool (Windows 95/98) or
the Disk Maker utility (Windows NT or Windows 3.11)
allows you to create installation diskettes from disk images preinstalled on the hard disk.
To back up other pre-installed software (and your own files)
use the Backup tool (Windows 95/98 and Windows NT) or
Backup for Windows (Windows 3.11).
In general, any copy you make of pre-installed software must be
used only as a back-up copy, in case the pre-installed version is lost.
OWNER’S HANDBOOK 2/5
Getting Started
You are not allowed to use installation diskettes created from disk
images to install the software onto another computer.
Improving your display settings
Your pre-installed copy of Windows is configured for a standard
monitor setting (640 x 480 pixels in a maximum of 256 different
colours), so that Windows is sure to display correctly whatever
monitor you have.
Most modern monitors, including Mitsubishi Electric monitors, can
display higher resolutions than standard VGA. You can change the
setting to one that more closely matches your own monitor, to get
the best performance from it.
Display settings in Windows 95/98 or Windows NT
The monitor setting is changed by using the Settings tab of the
Display Properties dialog. See Windows
changing display settings.

Getting Started
If your hard disk is larger than 2 gigabytes
If your Mitsubishi Electric PC is pre-installed with Windows 95 or
Windows 98, the entire hard disk is initially formatted as one
partition.
If you have Windows NT 4.0, the first 2 Gbytes are formatted
(using FAT) as a primary partition. The rest of the disk is
untouched. You can re-partition and reformat the disk using the
Disk Administrator tool in the Administrative Tools (Common)
folder.
If you have Windows 3.11 (Windows for Workgroups), the first 2
Gbytes are formatted as the primary partition. The remainder of the
disk is divided into formatted partitions of no more than 2 Gbytes
and no less than 512 Mbytes.

3 DISKETTES and CDs
Diskette drive
Your PC is fitted with a 1.44 Mbyte diskette drive. This accepts
either 1.44 Mbyte (HD) or 720 Kbyte (DD) diskettes.
Each diskette has a rigid plastic cover, with a metal shutter that
guards the disk surface. Never touch the exposed surface under the
shutter – you could deform the disk or leave a fingerprint that
might make the diskette difficult to read.
Keep diskettes away from dust, moisture, magnetic objects, and
equipment that generates magnetic fields. Also, avoid extremes of
temperature and exposure to direct sunlight. Otherwise, data
recorded on the diskette may become corrupted.
Inserting a diskette
1. Insert the diskette with the metal shutter foremost, and with
the label side facing upwards.

CD-ROM drive (optional)
The CD-ROM drive can retrieve multimedia data from CD-ROM
discs and multi-session Photo-CD discs. It can also play normal
music CDs (the drive has its own headphone jack and associated
volume control).
Keep CDs well away from dust and moisture, and avoid touching
the surface of the CD. Avoid extremes of temperature and exposure
to direct sunlight as these may cause the disc to warp.
