Step 4: Turn on the monitor and
computer
• Turn the monitor power switch ON. Then turn the
MONITOR 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.
