Step 2: 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.
Step 3: Turn on the monitor and
computer
First turn on the monitor, then turn on the computer.
The installation of your monitor is complete.
If necessary, use the monitor’s controls to adjust the picture.
If no picture appears on your screen
• Check that the monitor is correctly connected to the computer.
• If NO SIGNAL appears on the screen, try changing the input
signal (page 6), and confirm that your computer’s graphics
board is completely seated in the correct bus slot.
• If you are replacing an old monitor with this model and OUT
OF SCAN RANGE appears on the screen, reconnect the old
monitor. Then adjust the computer’s graphics board so that the
horizontal frequency is between 30 – 130 kHz and the vertical
frequency is between 48 – 170 Hz.

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 fields that could cause interference.
Ensure that the furniture or equipment can support the weight of
the monitor. Allow at least 2 inches (50mm) 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 keyboard to rest your wrists
when not typing. Consider using a wristpad.
Eyesight
Working with monitors, 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 comfortable 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.
