Page 40: Powering On
AUTOEXEC.BAT This file is a batch program that MS-DOS runs immediately after it executes the commands in the CONFIG.SYS file. AUTOEXEC.BAT contains commands that define the characteristics of the hardware devices. For example, AUTOEXEC.BAT identifies the port to which your printer is connected, customizes how MS-DOS information is displayed on your screen, and starts memory resident programs and applications.
Page 41 Power on (boot) your computer as follows. Check that the power cables from the monitor and system unit are connected to a wall outlet or surge protector. If you are booting from the hard disk, make sure that the diskette drive is empty. To boot from the diskette drive, be sure that you have a diskette in drive A containing operating system files.
Page 42: Powering Off
The system performs diagnostic tests that check major hardware components, such as memory and interface circuits. It compares the hardware it finds with parameters last saved by the Setup program. This process is the Power- On Self-Test (POST). Several configuration messages appear on the screen. NOTE You can bypass the POST memory test by pressing the space bar.
Page 43 Save your work. See the documentation that comes with your application program. Exit the application program. If you are in Windows, exit the Program Manager by double clicking on the upper left block. Select “OK” at the prompt to exit Windows. Make sure that the hard disk and diskette drives are not in use.

Page 99: Maintaining Your Computer
Protective Measures There are several ways that you can protect your system from possible damage. NEC strongly recommends the following protective measures: Connect a surge suppressor between your computer and a grounded wall outlet. A surge suppressor protects your system from sudden transient increases and decreases in electrical power.
Page 100 Chapter 2). Use appropriate virus detection software regularly to protect your system from computer viruses. If you plan to use software programs other than NEC supplied software, NEC strongly recommends that you take the necessary steps, such as virus checks, to protect your system.
Page 101: Routine Care
Routine Care Maintain the condition of your system by periodically following the general procedures listed below. WARNING: For safety, power off and unplug your system, monitor, and any external options before cleaning them. Clean the outside of the computer with a soft clean cloth. You can remove stubborn stains with a cloth slightly dampened with a mild detergent.
Page 102: Mouse Care
MOUSE CARE For best results with your mouse, use it on a mouse pad. Under normal conditions, your mouse has a self-cleaning mechanism that prevents a buildup of dust or lint around the mouse ball and tracking mechanism. Periodically, however, you might need to wipe the mouse ball clean.
Page 103: Cd Care
Clean the mouse as follows. Use tap water, or tap water and a mild detergent to clean the mouse ball. Use a clean, lint-free cloth to dry the ball. Blow into the mouse socket to remove remaining dust or lint. Gently put the ball back into its socket.
Page 104 Keep the disc away from direct sunlight or high tempera- tures. Clean fingerprints or dust from the disc by wiping it with a soft cloth. Gently, brush the cloth from the center of the disc toward the edge. CAUTION: Avoid using benzene, paint thinner, record cleaner, static repellent, or any other chemical on the disc.

ARRANGE YOUR EQUIPMENT Arrange your equipment so that you can work in a natural and relaxed position. Place items that you use frequently within easy reach. Adjust your workstation set-up to the proper height (as described in this appendix) by lowering the table or stand that holds your computer equipment or raising the seat height of your chair.
Page 225: Adjust Your Chair
ADJUST YOUR CHAIR Your chair should be adjustable. Keep your body in an upright position with the backrest adjusted to support your lower back. Maintain a comfortable, stable position. Check the following: The backrest of your chair should support the inward curve of your lower back.
Page 226 Your seat depth should allow your lower back to comfortably contact the backrest. Make sure that the backs of your lower legs do not press against the front of the chair. Extend your lower legs slightly so that the angle between your thigh and lower leg is slightly more than 90°.

ADJUST YOUR KEYBOARD AND MOUSE Follow these points in positioning your keyboard and mouse. Position your keyboard directly in front of you. Avoid reaching when using your keyboard or mouse. If you use a mouse, position it at the same height as the keyboard and next to the keyboard.
Page 228 Type with your hands and wrists floating above the keyboard. Use a wrist pad only to rest your wrists between typing. Avoid resting your wrists on sharp edges. Type with your wrists straight. Instead of twisting your wrists sideways to press hard-to-reach keys, move your whole arm.
Page 229: Adjust Your Monitor
ADJUST YOUR MONITOR Correct placement and adjustment of the monitor can reduce eye, shoulder, and neck fatigue. Check the following when you position the monitor. Adjust the monitor height so that the top of the screen is at or slightly below eye level. Your eyes should look slightly downward when viewing the middle of the screen.
