Read This First
Before you set up your EPSON®EL 486UC+ computer, read
this card for guidelines on how to get started. Also keep it
around for future reference because it provides important
information about your system and how to get technical
assistance when you need it.
Setting Up Your System
Most systems sold by EPSON Direct” are preconfigured; all the
hardware and software (such as MS-DOS® and Microsoft®
Windows™, is already installed. However, be sure to follow
these general procedures when setting up your system:
1. Install any internal options. If you purchased additional,
optional equipment that goes inside the computer—such as
option cards, memory modules, a hard disk, or a diskette
drive-you should install these devices first. See Chapters 4
and 5 in your User's Guide for instructions.
2. Set up the computer. Follow the steps in Chapter 1 of the
User's Guide to connect your system components and in
Chapter 2 to run the SETUP program.
3. Install your Windows applications and other software.
Install any Windows applications and other software
programs you plan to use. See the documentation that
came with the application programs for instructions.
Note
Be sure to make backup copies of all the diskettes you
use to set up your system and install your software.

4. Install VGA device drivers and utilities. If you have a
monitor that supports resolutions over 640 x 480, you’ll
probably want to use some of the VGA device drivers and
utilities that came with your computer to enhance the
display capabilities of your built-in VGA adapter. Drivers
for Windows have been installed on the hard disk. To
install additional drivers, see the README file on the
Utility diskette for instructions.

all warnings and instructions marked on the computer.
Unplug the computer before cleaning. Clean with a damp cloth only.
Do not spill liquid on the computer.
Do not place the computer on an unstable surface or near a radiator
or heat register.
Do not block or cover the openings in the computer’s cabinet. Do not
insert objects through the slots.
Use only the type of power source indicated on the computer’s label.
Connect all equipment to properly grounded power outlets. Avoid
using outlets on the same circuit as photocopiers or air control
systems that regularly switch on and off.
Do not let the computer’s power cord become damaged or frayed.
If you use an extension cord with the computer, make sure the total
ampere rating of the devices plugged into the extension cord does
not exceed the cord’s ampere rating. Also, make sure the total of all
devices plugged into the wall outlet does not exceed 15 amperes.
Except as specifically explained in this User's Guide, do not attempt
to service the computer yourself. Adjust only those controls that are
covered by the operating instructions.
Unplug the computer and refer servicing to qualified service
personnel under the following conditions:
If the power cord or plug is damaged; if liquid has entered the
computer; if the computer has been dropped or the cabinet damaged;
if the computer does not operate normally or exhibits a distinct
change in performance.
If you plan to use the computer in Germany, observe the following:
To provide adequate short-circuit protection and over-current
protection for this computer, the building installation must be
protected by a 16 Amp circuit breaker.
Beim AnschluB des Computers an die Netzversorgung muB
sichergestellt werden, dab die Gebäudeinstallation mit einem
16 A Überstromschutzschalter abgesichert ist.

ventilation avec commutation marche-arrêt automatique.
lS’assurer que le cordon d’alimentation de l’ordinateur n’est pas
abîmé ni effiloché.
lDans le cas ou on utilise un cordon de rallonge avec l’ordinateur,
s’assurer que l’intensite en amperes requise pour tous les appareils
branches sur ce cordon ne soit pas superieure a la capacite du cordon.
S’assurer aussi que cette intenste ne depasse jamais la somme de 15
amperes pour l’ensemble des appareils.
lSauf dans les cas specifiques expliques dans ce manuel de l’usager,
ne pas essayer d’entretenir ou de reparer l’ordinateur soi-même.
N’ajuster que les commandes décrites dans les directives.
lDebrancher l’ordinateur et contacter un technicien qualifié dans les

Introduction 1

Using the built-in interfaces, you can connect most of your
peripheral devices directly to the computer, so you do not have
to install option cards. You can use the option slots to enhance
your system with extra functions such as a modem card, a
network controller card, or additional interface ports.
The shadow RAM feature speeds up processing by moving the
system and video BIOS into the RAM area of memory.
With the standard 512KB of video RAM, the VGA controller
supports standard resolutions up to 640 x 480 in 16 colors and
extended resolutions up to 640 x 480 in 256 colors or 1024 x 768
in 16 colors (interlaced or non-interlaced). When you upgrade
to 1MB of video RAM, the system supports extended
resolutions up to 1024 x 768 in 256 colors.
Your system may have been configured for you. If so,
everything you need to get started is already in place. Your
hardware configuration options have been set to ensure
optimal system performance. The hard disk drive already
contains the MS-DOS®operating system and Microsoft@
Windows.TMIn addition, the drivers needed to take advantage
of your system’s enhanced video resolutions have been
installed for you. Just connect your keyboard, mouse, and
monitor and you’re ready to go.
VGA Drivers
Your computer comes with VGA drivers for use with the
integrated VGA interface. With these drivers, you can take
advantage of the extended VGA features such as high
resolutions and 132-column text mode when you run popular
application programs. If your system was configured for you,
these drivers are already installed. If you need to install them
yourself, a README file on your Utility diskette describes how
to install the VGA drivers for common application programs.
