FCC COMPLIANCE STATEMENT FOR AMERICAN USERS

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:

Reorient or relocate the receiving antenna

Increase the separation between the equipment and the receiver

Connect the equipment to an outlet on a circuit different from that to which the receiver is connected

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 sur le brouillage radioélectriques édicté par le Ministère des Communications du Canada.

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

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

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

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

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.)

1-6

Setting Up Your System

Plug the monitor’s power cord into the monitor’s power inlet, as shown below.

Plug the other end of the power cord into an electrical outlet.

Setting Up Your System

1-7

Connecting a Printer or Other Device

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:

Be sure the power switches on the computer, monitor, and printer are off.

Place the printer next to the computer.

Setting Up Your System

1-8

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

1-9

Connect the other end of the cable to the printer, as shown below. To secure the cable, squeeze the clips at each side of the printer port and push them into place.

Plug the printer’s power cord into an electrical outlet.

1-10

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.
