QUICK START GUIDE

MITSUBISHI PEDION QUICK START GUIDE

This Quick Start Guide gives you the minimum amount
of information needed to start working with your new
Pedion.

More detailed in formation is provided in the Owner’s
Handbook (the second part of this book).

Throughout this book “Windows” means Microsoft
Windows 95. If Windows 98 or Windows NT is
installed on your Pedion, certain procedural details may
change. Consult your Windows documentation
(manual or help files) for assistance.

For your own safety

Read through the Safety & Regulatory Notices section at the
start of this manual before using the computer for the first time.

1

QUICK START GUIDE

Connecting to the AC power supply

AC
outlet

Begin by connecting the P edion to the AC power supply.
This is necessary becuase the Pedion's internal battery is
initially uncharged.

1. Connect the AC adapter to the DC-IN connector on
the rear of the Pedion.

2. Connect the power cord to the AC adapter , and plug
the power cord into a nearby AC outlet.

Warning

Use only the AC adapter that comes with y our Pedion. Do not
attempt to use an adapter from any other equipment.

Caution

Use only with a 120-240 volt A C po wer supply.
Place both the computer and the Pedion on a stable surface (e.g.

desktop or floor). If the AC adapter becomes detached from the
system because, for example, the adapter falls off of a desktop, the
power will be cut off, which may cause data loss.

2

Charging the internal battery

QUICK START GUIDE

The Pedion's internal battery begins to charge as soon as
you connect the P edion to the AC power supply.

We recommend that you let the battery fully charge
before using the Pedion for the first time. This should
take about 3 hours. (If you use the Pedion while the
battery is charging, it could take up to 12 hours.)

A fully charged battery should enable the computer to be
used without an AC power supply for about 1.8 hours.

The Pedion's B attery Status light (the middle of three lights
on the right-hand side) is orange while the battery is
charging, green when it is charged.

A new battery may run down relatively quickly. This is
quite normal. If you fully recharge the battery each time it
runs down, it will soon achieve its optimum performance.

For more information, see the chapter on “Battery and
Power Management” in the Owner’s Handbook.

Note

The batteries in the optional Battery Pack are also initially
uncharged. If the Battery Pack is attached to the P edion, both
the Battery Pack and the Pedion's internal batter y can be
recharged at the same time.

3

QUICK START GUIDE

Attaching the Multimedia Pack

Once the Pedion’s battery has been fully charged, you
can connect the Multimedia Pack.

1. Ensure the Pedion is turned off.

2. Close the LCD panel and turn the Pedion over.

3. Slide open the battery and multimedia connector
covers on the underside of the Pedion.

4. Align the two small holes on the rear of the Pedion
with the two raised catches on the rear edge of the
Multimedia Pack.

5. Gently press down on the front edge of the Pedion
until it clicks into place. Do not use excessive force.

For more information, see the “Welcome” chapter in
the Owner’s Handbook.

4

Starting the Pedion

QUICK START GUIDE

To start the Pedion

1. Slide the latches on the sides of the P edion forward
to release the LCD panel, then open it.

2. Adjsut the angle of the LCD panel until you can
view the display comfortably.

3. Press the Power button. The Power Status light
turns green and Windows starts.

5

QUICK START GUIDE

Using the touchpad

The touchpad consists of a touch-sensitive tablet and
two buttons, which together perform the same function
as a mouse. The left and right touchpad buttons
correspond to left and right mouse buttons.

For more information, see the chapter on “ Touchpad
and Keyboard” in the Owner’s Handbook.

Be careful!

Don’t use the touchpad if your fingers are wet.
Don ’ t press too hard on the tablet ’ s surface. You could break it or

hurt yourself.

To move the cursor

♦ Slide your fingertip over the surface of the tablet.

To move the cursor a large distance, move your
finger in the required direction several times in
succession. Only slight movement is needed for
more accurate positioning of the cursor.

To left-click

♦ Tap once with your finger tip.

T o double-left-click

♦ Tap twice with your finger tip.

T o click-and-drag

♦ T ap twice, but hold your finger on the tablet’ s surface

on the second tap, then slide your finger tip across
the tablet’ s surface.

OR

♦ Press and hold down the left touchpad button, then

slide your finger tip accross the tablet’ s surface

6

Registering and configuring Windows

QUICK START GUIDE

Registering Windows

Your computer has the Microsoft Windows operating
system already in place or pre-installed, so that it is ready for
you to set up when you turn the computer on.

The first time you start the Pedion you must tell W indows
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. It also gives you the
opportunity to install a printer. Ho wever , you do not have
to install a printer at this time if you don ’ t want to.

Y ou only register once

All of this only happens the first time you turn on your computer .
After that Windows starts normally, except that you may be
reminded if you haven’t made any back-up diskettes yet.

Increasing the resolution and colours
displayed by the LCD panel

At first, Windows is configured for a display setting of 800
by 600 pixels in High Colour (16 bit).

The Pedion’s LCD panel can do better than this setting.
You should therefore change the display setting to get
the best performance from your system.

1. Move the cursor into an unoccupied area of the
Windows desktop and press the right touchpad
button, then select Properties from the pop-up
menu.

2. Click the Settings tab of the Display Properties dialog.

3. You can now select the Desktop Area (resolution)
and Colour Palette (number of colours). We
suggest 800 by 600 pixels in True Colour (24 bit).

7

QUICK START GUIDE

Conserving battery power

Tips on conserving battery power

♦ Whenever possible, work with the AC adaptor

connected and plugged in to the supply. That way,
the Pedion’s internal batter y recharges while you
work.

♦ To pause briefly when working, close the LCD

panel. This puts the Pedion to sleep (Memory
Suspend mode). To resume working, open the
LCD panel and press the Power button.

♦ For more lengthy interruptions in your work, press

the Power button and wait for everything to be
saved to disk (Disk Suspend mode). To resume
working, press the Power button again.

♦ When you’ve finished work, shut down Windows

in the normal way. This automatically turns off
the Pedion.

For more information, see the chapter on “B attery and
Power Management” in the Owner’s Handbook.

How long can I work on battery
power?

Internal battery only

Lasts for up to................................................ 1.8 hours

Recharge (while working) .............................12.0 hours

Recharge (while turned off)............................3.0 hours

Internal battery plus optional Battery Pack

Lasts for up to................................................ 7.2 hours

Recharge via P edion (while working).............30.0 hours

Recharge via P edion (while turned off)............8.0 hours

Recharge directly via AC adaptor .................... 8.0 hours

These times depend on the programs you are running and
how much use you make of the hard disk and CD-ROM
drive.

8

Shutting down the Pedion

QUICK START GUIDE

Normal shutdown

To shut down the Pedion safely:

1. Wait until all the activity indicators on the Pedion
and Multimedia Pack show ‘not busy’.

2. Remove any diskettes and CDs from the
Multimedia Pack.

3. Turn off any attached peripherals.

4. Click the Start button in the Windows task bar,
then click Shutdown.

5. Select Shut down the computer and click Yes.
Windows shuts down. The P ower S tatus light goes

out.

Emergency shutdown

In exceptional circumstances you can insert the tip of a
pencil (or similar non-metallic object) into the
Emergency OFF hole below the left side of the keyboard.
This turns off the Pedion without shutting down
Windows first. Any unsaved work will be lost.

Use the emergency shutdown procedure only if the
Pedion stops responding, and pressing Ctrl + Alt + Del
doesn’t restart Windows.

Make sure it is an emergency!

In an emergency shutdown, you may lose any recent changes
made to the files you are working on. The Microsoft ScanDisk
program will run automatically when the computer next
starts, to check for disk errors.

9

QUICK START GUIDE

Where to get more information

There are various help files available on the computer.
In particular, you should use Windows Help, which
can be accessed from the Start menu, to help with
Windows-related problems. We also recommend that
you double-click the Important Apricot User
Information icon on the Windows desktop for late­breaking information relating to your computer.

Backing up the pre-installed software

Creating an emergency startup disk

We strongly recommend that you create an emergency
startup disk. This will enable you to start Windows in
the event of your existing Windows software
becoming corrupted.

1. On the Start menu, point at Settings, then click
Control Panel.

2. In the Control Panel, double click the
Add/Remove Programs icon.

3. On the Startup Disk tab of the Add/Remove
Programs Properties dialog, click Create Disk.

4. Insert a formatted, 1.44 Mbyte diskette into the
diskette drive. Follow the on-screen instructions.

Backing up your system

We also recommend that you copy or ‘back-up’
Windows and any other pre-installed software soon
after setting up the system. This is particularly
important for systems supplied without installation
disks 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 utility

allows you to create installation diskettes from
disk images pre-installed on the hard disk.

♦ To back up other pre-installed software (and

your own files) use the Backup tool. Click the

Start button in the Windows taskbar, then
Programs, Accessories, System Tools and
Backup.

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. You are not allowed to
use installation diskettes created from disk images to
install the software onto another computer.

1/8 Welcome

General advice

OWNER’S HANDBOOK

As a portable computer, this machine is designed to
be used in various environments. The following
paragraphs contain guidelines in caring for yourself
and your computer.

♦ Place the computer on a firm, level surface if

possible, away from vibration.

♦ Use 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).

♦ In winter, moving the computer from outdoors

to the warm indoors can cause moisture to
condense inside the system. Allow time for the
computer to dry out before turning it on.

♦ Make sure there is adequate space around the

computer for ventilation.

♦ Always handle the computer gently.

♦ Ensure that you maintain a healthy posture

when using the computer. Ideally, your feet
should be on the floor and your legs at right
angles, with your upper legs approximately
horizontal. Your back should be kept straight,
and your elbows should be about the same
height as the keyboard. Also, your eyes should
generally be approximately 0.5m from the
display, with the top of the screen as close to
your direct line of vision as possible.

0.5m

Welcome 1/9

OWNER’S HANDBOOK

♦ Avoid using the computer when placed directly

on your lap for long periods. It can generate
enough heat to cause low-temperature burns.
(redness or blisters)

♦ When positioning the computer, 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 screen as glare, and that the keyboard is
placed in a comfortable position for typing.

♦ You should be aware that in some places, the use

of a portable computer is strictly forbidden. For
example, you should check before using your
portable computer inside a hospital, or before
boarding an aircraft.

The touchpad consists of a touch-sensitive tablet and
two buttons, which together perform the same
function as a mouse. The left and right touchpad
buttons correspond to left and right mouse buttons.

How to use the touchpad

♦ Touch the tablet only with your finger tip.

Don’t use your fingernails or a pen, or wear a
glove.

♦ Touch only one place on the tablet’s surface.

Touching two or more places at the same time
confuses the software.

♦ Tapping the tablet’s surface acts like clicking a

left mouse button.

Caution

Don’t use the touchpad if your fingers are wet. Don’t
press too hard on the tablet’s surface; you could break it
or hurt yourself.

Touchpad gestures

The basic touchpad gestures are as follows

♦ To move the cursor: Slide your finger tip across

the surface of the tablet. To move the cursor a
large distance, move your finger in the required
direction several times in succession. Only slight
movement is needed for more accurate
positioning of the cursor.

♦ To left-click: Tap once with your finger tip.
♦ To double-left-click: Tap twice with your finger

tip.

♦ To click-and-drag: Tap twice, but hold your

finger on the tablet’s surface on the second tap,
then slide your finger tip across the tablet’s
surface.

4 BATTERY & POWER MANAGEMENT

Using battery power

OWNER’S HANDBOOK

The Pedion can operate from its internal battery for
up to 1.8 hours, depending on the programs you are
running and how much use you make of the hard disk
and CD-ROM drive.

An optional Battery Pack can be attached to the base
of either the Pedion or the Multimedia Pack,
extending the operating time to up to 7.2 hours.

You can recharge the internal battery and the Battery
Pack 300 to 500 times before their performance starts
to degrade. At this point you should contact your
Mitsubishi Electric PC dealer or maintainer.

General advice

♦ At first, the internal battery is not charged.

Before using your Pedion for the first time, you
must charge the battery. The same applies to the
optional Battery Pack.

♦ A new battery may be discharged in an

unexpectedly short time. Fully recharge it before
using it again.

♦ You should recharge and discharge fully each

time. Partial recharges/discharges will shorten
the battery’s lifetime.

♦ Extreme temperatures (high or low) will shorten

the battery’s lifetime.

♦ Neither the Pedion’s internal battery nor the

batteries in the Battery Pack can be removed. If
they become worn out, contact your Mitsubishi

Connecting an infrared device

The Pedion can use the same kind of infrared signal
as that used by a TV or video remote control to
communicate with another computer or peripheral
device. The Pedion supports the IrDA 1.0 and IrDA

1.1 Fast Infrared (FIR) standards promoted by the
Infrared Data Association.

When using the infrared port, it is important to
ensure that the two devices about 1 metre apart and
within an angle of 15 degrees of a clear line-of-sight
between the two ports.

General advice on IR communication

♦ Communication is one-to-one only.
♦ Communication under a fluorescent lamp may

decrease the speed of data transfer.

♦ Keep TV or VCR remote controls away from

the effective range of the infrared ports.

♦ During communication, do not move the two

communicating devices.

♦ The Pedion is configured at the factory to use

the IrDA 1.0 standard. If necessary, you can
change this to Fast Infrared with the BIOS
Setup utility and the Windows Control Panel.

Infrared Monitor

An Infrared Monitor program is provided to help you
keep track of the Pedion’s infrared activity. The
Infrared Monitor can normally be opened by double­clicking the Infrared icon in the Windows taskbar.

Infrared icon

The default settings of the Infrared Monitor ensure
that the Pedion searches for infrared devices within
range every 3 seconds. If a suitable device is found,
and provided that it is Plug and Play aware, its
associated software can be installed automatically and
communication can begin.

With the Infrared Monitor, you can:

♦ Find out what infrared devices are within range.
♦ Find out if the Pedion is currently

communicating with an infrared device, and if it
is, how well it is communicating.

♦ Control how Infrared Monitor reports status on

Connecting a USB device

The Pedion and the Multimedia Pack each have one
USB (Universal Serial Bus) port. If the Pedion is
docked with the Multimedia Pack, both ports can be
used simultaneously.

About the Universal Serial Bus (USB)

The USB is a relatively new way of connecting
peripherals to your computer. It has several
advantages over existing serial and parallel ports.

♦ Several USB devices can be “daisy-chained”

together.

♦ USB devices are “hot-pluggable”; that is, they

can be plugged in and disconnected without
turning off the computer.

♦ The USB can supply DC power to certain

devices, so that they do not need an
independent power supply.

USB is also quite fast, operating at 12 megabits per
second, which is appropriate for a wide range of
applications including video conferencing cameras.

To connect a USB device

Before connecting any USB device, we recommend
that you read all documentation provided with the
device.

6 BIOS SETUP

Using the Setup utility

OWNER’S HANDBOOK

The BIOS (Basic Input/Output System) mediates
between the computer’s hardware – the processor,
memory, and so on – and its software – the operating
system and your programs. The BIOS program is
kept in permanent, read-only memory or ROM.

Setup is a helpful utility that forms part of the BIOS
program. It allows you to view and alter the
computer’s hardware configuration. Configuring the
computer may be necessary to ensure that the
software you use can recognise and exploit the
hardware’s capabilities.

The current configuration is kept in a special area of
memory, called CMOS memory, and maintained by a
battery so that the configuration is preserved even
while the computer is switched off.

Your computer arrives already configured, but may
need to be configured again in certain circumstances.

Whenever the computer is turned on, the BIOS
power-on self-test (POST) routine tests various
hardware components, including memory, and
compares the actual configuration of the computer
with that recorded in permanent (CMOS) memory.

Using the Setup utility is fairly straightforward; all of
the options and control keys available are constantly
displayed at the bottom of the screen, and there is
item-specific help displayed on the right of the screen
for whichever item is currently selected.

The Setup utility contains the following main menu
screens:

♦ Main
♦ Advanced
♦ Security
♦ Power Saving
♦ Exit

BIOS Setup 6/1

OWNER’S HANDBOOK

There are many parameters which can be changed in
the Setup utility. These can easily be reviewed by
browsing through the Setup utility itself, and are
therefore not covered in detail here.

Getting help in Setup

You can get general help about the control keys at any
time by pressing the

F1

key.

The Help window on the right-hand side of each
screen displays help text for the currently-selected
field. It changes as you move the cursor from one field
to another.

To start the Setup utility

1. Turn on or restart the Pedion.

2. Wait until the “Pedion Mobile Computer” logo
appears on the screen.

key.

3. Press the

F2

4. If you have previously defined a Supervisor
password, you are prompted for it before Setup
starts.

If Setup starts on its own

Setup might start on its own for the following reasons:

♦ The power-on self-test (POST) detects a

configuration error or fault. This may be
signalled by one or more POST error messages.
If a persistent fault is indicated, make a note of
any error messages and the current Setup
configuration settings before calling an
authorised maintainer.

♦ The CMOS battery may be running down. This

may cause spurious POST error messages. If this
happens every time you turn on the computer,
you may have to change the battery. Contact
your Mitsubishi Electric PC supplier or
maintainer to have the CMOS battery renewed.

6/4 BIOS Setup

The most useful options within Setup

OWNER’S HANDBOOK

Advanced, I/O Device Configuration

Use the options in this sub-menu to configure the
serial, infrared and parallel ports.

The IR port (Serial Port B) is initially set to IrDA

1.0 mode; if necessary, you can change this to
IrDA 1.1 Fast Infrared (FIR) mode, which requires
DMA1 or DMA3.

The parallel port is initially set to Bi-Directional
mode; you can change this to Extended Capabilities
Port or Enhanced Parallel Port mode (ECP requires
DMA1, DMA2 or DMA3). The parallel port can
be disabled to save power.

DMA requirements mean that the Pedion cannot
use the diskette drive and the FIR, ECP and audio
features at the same time. If necessary, you can
disable the diskette drive to free DMA2. The audio
system requires DMA0 and DMA1 and cannot be
disabled.

Power Saving

You can use these options to configure the Pedion’s
power saving modes and features, although the
factory settings will serve for most situations. You
can redefine the action of the Power button, and set
automatic timeouts for Disk Suspend and Standby
modes, and hard disk and video activity.

Security

You can use these options to define a Supervisor
password that is required every time you start the
Setup utility. Optionally, the password can also be
required every time you start the Pedion.

To set a Supervisor password

1. Start the Setup utility.

2. Select the Security menu.

3. Select Set Supervisor Password them press

6. If you want the password to be requested every
time you start the Pedion, set Password on
boot to “Enabled”.

7. Exit from Setup, saving changes.

You can use this procedure to change the password,
except that you will have to type the old password
before you type the new password (or press

Enter

, if

you want to delete the old password).

Once you define a Supervisor password, you can
also define a User password. This works like the
Supervisor password except that certain critical
options in the Setup utility are not available.

If a password is typed incorrectly three times in a
row, the message

SYSTEM DISABLED

is displayed
and the system halts. In this situation, you must
insert a non-metallic probe into the Emergency
OFF hole to turn off the Pedion, then press the
Power button to turn it on again.

If you forget the password, contact your Mitsubishi
Electric PC supplier or authorised maintainer.
