Federal Communications Commission (FCC) Statement
Radio Frequency Interference Statement
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 protection 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 receiver.
• Connect the equipment into 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.
Any special accessories needed for compliance must be specified in the
instruction manual.
Warning: A shielded-type power cord is required in order to meet FCC
emission limits and also to prevent interference to nearby radio and
television reception. It is essential that only the attached power cord be
used.
Use only shielded cables to connect I/O devices to this computer.
You are cautioned that changes or modifications not expressly approved by
the party responsible for compliance could void your authority to operate
the 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 regula-
tions of the Canadian Department of Communication.
Le Present appareil numérique n’émet pas de bruits radioélectriques
dépassant les limites applicables aux appareils numériques de Class B
preescrites dans le reglement sur le brouillage radioélectrique édicté parle
Ministere des Communications du Canada.
Warning
Reconfiguring
• To keep the computer from being damaged, NEVER reconfigure the board while the power is ON.
• If you wish to reconfigure the computer at any time, ensure that
the power is turned OFF before changing any hardware settings, such as DIP switches or jumpers.

How to Use this Manual
For the advanced user
If you are an experienced PC user and do not want to upgrade your
system now and you want to start using your personal computer as
soon as possible, refer to the Quick Start section at the beginning of
chapter one.
Quick Startwill provide you all the information you need to set up the
hardware.
For the beginner
Chapter 1 gives you the basic information you need to use this
system. Chapter 2 provides greater detail on the hardware and on
how to upgrade your system. Your system is quite simple to set up.
However if you are unsure of yourself, find an experienced PC hand
to help out.

1-1 Introduction
This manual will guide you through the setup of your computer and
provide the information necessary to tailor the system to fit your needs.
If you are a novice, you will be able to have your computer up and
running with a minimum of fuss. You will also gain valuable hands-on
experience by following the easy step-by-step instructions. If you are
an advanced user, you will appreciate the affordable power of this
system.
Your system uses an Intel 80386-25 microprocessor with 80387-25 or
Weitek WTL3167-25 coprocessors optional. While maintaining complete compatibility with software written for IBM PC/AT 80286-type
computers, your computer vastly exceeds them in capability and
processing power. The PEI-306 RAM Card maintains the highest
performance and flexibility for the whole system. The PEI-306 RAM
Card is specifically designed for some DTK 386 or higher level
products for memory expansion. It is not compatible with mainboards
produced by other companies and you can buy it from a dealer who
sells DTK products. Also, a wide variety of expansion cards are
available for your choice of peripherals.
Quality, flexibility, and functionality are the key design features of your
system.
Operating System
Your computer uses the MS-DOS® operating system. For more details
on this operating system, please refer to the Microsoft® MS-DOS
User’s Guide and User’s Reference. This manual is included with your
system.

If you are an experienced user anxious to stat-t using your computer,
observe the figure below to set up your personal computer. You will still
want to use this manual later as a reference book.
Note: Save all packing materials in case you need to ship or resell your
computer in the future.

1-5 Example of a System Configuration
Chapter 1: System Overview
The basic system is pictured below. You may choose peripherals and
upgrades for the system as your needs require. Even if your system is
different from the one pictured, it should operate in the same basic
manner.
Figure 1-2: System Configuration

1-6 System Unit
Chapter 1: System Overview
The system unit may house a motherboard, disk drives, a power supply
and other optional expansion cards.
Figure 1-3: System Unit Case
7
1-7 Control Panel
The control panel provides several useful functions which are explained below. You are likely to use the front panel frequently, so let’s
start there.
Figure 14: Front Panel
Reset Button
The reset button allows you to restart the system without turning the
power off. If you encounter any problems while using unfamiliar
software, you can always restart quickly from the RAM test stage by
pressing the reset button. Note, however, that any data which have not
been saved to disk will be lost.
Turbo Button
The Turbo button allows you to change the running speed of the
microprocessor to accommodate software requirements. Some
software applications must be run at a slow clock speed.
Indicator Lights
These lights indicate the operation status of your computer. The red
LED comes on when the hard disk is being accessed. The green LED
is lit when the power is on. The yellow LED comes on when Turbo clock
speed is activated.

Keyboard Lock
Chapter 1: System Overview
The keyboard lock enables or disables the keyboard. In the unlock
mode the keyboard is activated. In the lock mode, the keyboard is
disabled to deny unauthorized user’s access to the computer.

System Power Switch
The system power switch is located on the right side of the case toward
the rear. You should always be certain that the power is turned off
before modifying the hardware configuration in any way.
Figure 1-6: Power Switch
9
1-8 Rear Panel
The rear panel has all the connections that lead from the system unit
to external peripherals and the power source. Turn off all power
switches before connecting or disconnecting cables/wires! En-
sure that cables/wires are attached to the external device first and
connected to the outlet unit later. Turn the system unit power switch off
before you plug the power cable into an electrical outlet.
Figure 1-7: Rear Panel

Chapter 1: System Overview
Keyboard Connector
The keyboard supplied with your system can be plugged into sockets
at back of the case. Plug the keyboard cable into the socket as shown
below.
Figure 1-8: Connecting the Keyboard Cable
Chapter 7: System Overview

Power Cord Connector
The power supply has two receptacles: one supplies power to a
monitor; the other connects to the main power source.
Yet, if your monitor power plug does not fit the system unit’s monitor
power outlet, you should plug it into a wall electrical outlet.
Figure 1-9: System Power Cord
12
Chapter 1: System Overview
Display Port
You will also need to connect your monitor to the system unit at a
female display port in one of the expansion slots as shown on the
previous page.
To attach the monitor cable to the video port, plug the cable into the
port and screw the cable connector down securely.
‘four computer gives you a wide range of video options to meet your
needs.
You have a wide choice of the following video standards.
— MGA (Monochrome Graphics Adapter) also referred to as
Hercules
— CGA (Color Graphics Adapter)
— EGA (Enhanced Graphics Adapter)
— VGA (Video Graphics Adapter)
‘four monitor power plug may not fit the system unit’s monitor power
outlet.
If not, connect the monitor cable to a wall electrical outlet.
