Step 4: Turn on the monitor and

computer

• Turn the monitor power switch ON. Then turn the

computer power switch ON, by pressing the switch

inward. The green power indicator will light up.

• Allow about 30 seconds for the CRT tube to warm

up. Data will be displayed on the screen.

• If your display fails to function properly, please

first refer to the section "Troubleshooting" in this

manual.

Workplace Preparation

Positioning the Monitor

Choose a suitable place to position the monitor where

it is not near fluorescent desk lighting or any

equipment that produces magnetic field that could

cause interference.

Ensure that the furniture or equipment can support

the weight of the monitor. Allow at least 2 inches (50

mm) ventilation space around the monitor.

Height

The monitor should be positioned so that the top of

the screen is slightly below your eye level when you

sit at your workstation.

Orientation

Choose a position that gives the least reflection from

lights and windows, usually at a right angle to any

windows. The monitor should be positioned directly

in front of you so that you do not have to twist your

body. Tilt the monitor to a comfortable viewing angle.

Working Practices

Rest

Take regular breaks. Vary your posture, and stand up

and stretch occasionally as prolonged use of computer

workstations can be tiring.

Back

You should sit back in the chair and use the backrest.

Hands

Use a light touch on the keyboard, keeping your hands

and fingers relaxed. Allow a space in front of the key-

board to rest your wrists when not typing. Consider

using a wristpad.

Eyesight

Working with monitor, in common with any kind of

prolonged close work, can be visually demanding.

Look away from the screen periodically and have your

eyesight checked regularly.

Screen settings

Set the screen brightness and contrast to a comfort-

able level. You may have to adjust this as the lighting

changes during the day. Many application programs

let you select color combinations which can help you

to view in comfort.

Step 3: Connect the power cord

With the monitor and computer turned off, first

connect the proper power cord for your local supply

to the monitor, then connect it to a properly grounded

power outlet.
