This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to
provide reasonable protections against harmful interference in a residential
installation. This equipment generates, uses, and can radiate radio frequency energy
and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
l
Reorient or relocate the receiving antenna
l
Increase the separation between the equipment and the receiver
l
Connect the equipment to an outlet on a circuit different from that to which

l
Consult the dealer or an experienced radio/TV technician for help.
You may find the following booklet prepared by the Federal Communications
Commission helpful:
“Television Interference Handbook”
This booklet is available from the U.S. Government Printing Office, Washington DC
20402. Stock No. 004-000-00450-7
Note: If the interference stops, it was probably caused by the computer or its peripheral devices. To further isolate the problem:
Disconnect the peripheral devices and their input/output cables one at a time. If the
interference stops, it is caused by either the peripheral device or its I/O cable. These
devices usually require shielded I/O cables. For Epson peripheral devices, you can
obtain the proper shielded cable from your dealer. For non-Epson peripheral devices,
contact the manufacturer or dealer for assistance.
WARNING: This equipment has been certified to comply with the limits for a
Class B computing device, pursuant to Subpart B of Part 15 of FCC Rules. Only
peripherals (computer input/output devices, terminals, printers, etc.) certified to
comply with the Class B limits may be attached to this computer. Operation with
noncertified peripherals is likely to result in interference to radio and TV
reception.
The connection of a nonshielded equipment interface cable to this equipment will
invalidate the FCC Certification of this device and may cause interference levels
that exceed the limits established by the FCC for this equipment.
This digital apparatus does not exceed the Class B limits for radio noise emissions
from digital apparatus as set out in the radio interference regulations of the Canadian
Department of Communications.
Le present appareil numérique n’émet pas de bruits radioélectriques dépassant les
limites applicables aux appareils numériques de Classe B prescrites dans le règlement

Introduction 5
Chapter 1
Setting Up Your System
Setting up your Epson Equity 386/25 personal computer is easy.
Just follow the seven steps in this chapter. As you set up your
computer, you may want to leave this manual’s back cover
foldout open so you can refer to the two illustrations identifying
the different parts of the computer.
Unpacking
1
As you remove your system components from their cartons, be
sure to inspect each piece. If anything is missing or looks
damaged, check with your Epson dealer.
Setting Up Your System
1-1
Besides this manual, you should have the following:
The computer and power cord
The keyboard with attached cable
Two keys for locking the computer
Six MS-DOS 4.01 diskettes: Install, Operating 1,
Operating 2, Operating 3, Shell, and Select
A Reference diskette
Four MS-DOS manuals: an Installation Guide, a Shell
User’s Guide, a Reference Manual, and a Command
Summary.
In addition to these items, you need a compatible monitor and
display adapter card. You may also have a printer or other
peripheral device.
You’ll find a warranty card and a registration card with the
computer. Keep the warranty card for your records. Fill out the
registration card now and mail it to Epson. With your
registration card on file, Epson can send you update
information.
Be sure to keep your packing materials. They provide the best
protection for your computer if you need to transport it later.
1-2
Setting Up Your System
Removing the Diskette Drive Protector Card
There is a protector card in the diskette slot of your 5 ¼-inch
diskette drive. This card is inserted at the factory to protect the
read/write heads in the drive. To remove it, turn the diskette
drive latch up until it is horizontal. This causes the card to pop
out slightly so you can pull it out of the slot, as shown below.
(If you have a second 5 ¼-inch diskette drive, be sure to remove
the card from that drive as well.)
Save the protector card and reinsert it whenever you move the
computer. If you don’t plan to use your computer for a week or
more, reinsert the card to help prevent dust from entering the
drive.
Setting Up Your
System
1-3
Choosing a Location
2
Before you set up your computer, it’s important to choose a
comfortable, convenient location where it can run properly.
Select a location that provides the following:
A large, sturdy desk or table that can easily support the
weight of your system, including all its components.
A flat, hard surface. Soft surfaces like beds and carpeted
floors attract static electricity, which can erase data on your
disks and damage the computer’s circuitry. Soft surfaces also
prevent proper ventilation.
Good air circulation. Air must be able to move freely under
the system as well as behind it. Leave several inches of space
around the computer to allow ventilation.
Moderate environmental conditions. Protect your computer
from extremes in temperature, humidity, dust, and smoke.
Avoid direct sunlight or any other source of heat. High
humidity also hinders operation, so select a cool, dry area.
Appropriate power sources. To prevent static charges,
connect all your equipment to three-prong, 120-volt
grounded outlets. You need one outlet for the computer, one
for the monitor, and additional outlets for a printer and any
other peripherals. You can plug one peripheral into the
auxiliary power outlet on the back panel of the computer,
reducing the number of wall outlets you need.
No electromagnetic interference. Locate your system away
from any electrical device, such as a telephone, that
generates an electromagnetic field.
1-4
Setting Up Your System
Connecting a Monitor
3
The procedure you use to connect your monitor to the
computer depends on the type of monitor you have. See your
monitor manual for detailed instructions and follow the general
guidelines below.
A monitor requires that a display adapter (video) card be
installed inside the computer to control it. Your dealer may
have already installed a video card for you; if not, you need to
install it before you can connect the monitor to the computer.
See Chapter 5 for instructions on how to remove the computer’s
cover and install an option card (a video card in this case).
First, check the following table to make sure your video card
and monitor match.
Monitor/video card compatibility
Setting Up Your System
1-5
After your video card is installed, follow these steps to connect
the monitor to the computer:
Place your monitor on top of or near the computer. It is
easiest to connect the monitor cable if the backs of the
monitor and the computer are facing you.
If necessary, connect the monitor cable to the monitor.
(Some monitors come with permanently attached cables.)
Connect the appropriate end of the monitor cable to the
video card connector on the back of the computer, as
shown below. If the plug has retaining screws, tighten them
by hand or with a screwdriver, depending on the screw type.
If there are any switches or jumpers on the video card (for
4.
example, to indicate color or monochrome), be sure they
are set properly. (See the documentation that came with
your monitor or video card for instructions.)

The Equity 386/25has a parallel interface, a serial interface, and
an auxiliary mouse connector. To connect a printer or other
peripheral device to one of these interfaces, follow the
instructions below. Of course, Epson offers a full range of
printers; check with your dealer for more information.
Using the Parallel Interface
The parallel interface on your computer is Centronics®compatible and uses a DB-25S connector.
To connect a printer to the computer, you need an IBMcompatible printer cable. If you are not sure which one you
need, check with your Epson dealer.
Once you have the correct printer cable, follow these steps to
connect your printer to the parallel interface on the computer:
1.
Be sure the power switches on the computer, monitor, and
printer are off.
2.
Place the printer next to the computer.
Setting Up Your System
1-8
3.
One end of the printer cable has a 25-pin, D-shell, male
connector. Connect this end to the parallel port on the
back panel of the computer, as shown below. If the plug has
retaining screws, tighten them by hand or with a
screwdriver, depending on the screw type.
Setting Up Your System

Setting Up Your System
Using the Serial Interface
If you have a printer, a modem, or any other peripheral with a
serial interface, you can connect it to the serial (RS-232C) port
on the back of the computer.
The Equity 386/25
uses a DB-9P male connector, so be sure you
have a compatible cable. To connect a serial device, follow the
same steps as above for connecting a parallel device.
Setting Up Your System
1-11
Using the Mouse Connector
Your computer has an auxiliary port for a PS/2™- compatible
mouse that uses a mini DIN (6-pin) connector. To connect a
mouse to the built-in mouse port and set up the computer to use
it, see the manual that comes with the mouse. To use a mouse
with your computer, you may need to add commands to your
MS-DOS CONFIG.SYS file. See your MS-DOS Reference
Manual for instructions.
