Operating Instructions
Use of the Tilt-Swivel
Precautions
This monitor can be adjusted within the angles shown below. To
find the center of the monitor’s turning radius, align the center of
the monitor’s screen with the centering mark on the stand.
Hold the monitor at the bottom with both hands when you turn it
horizontally or vertically. Be careful not to pinch your fingers at
the back of the monitor when you tilt the monitor up vertically.
Installation
Do not install the monitor in the following places:
• on surfaces (rugs, blankets, etc.) or near materials (curtains,
draperies, etc.) that may block the ventilation holes
• near heat sources such as radiators or air ducts, or in a place
subject to direct sunlight
• in a place subject to severe temperature changes
• in a place subject to mechanical vibration or shock
• on an unstable surface
• near equipment which generates magnetism, such as a
transformer or high voltage power lines
• near or on a magnetically charged metal surface.
• in a small space around the top, bottom and sides of the monitor
that may block the ventilation holes.

Maintenance
Centering mark
• Clean the cabinet, panel and controls with a soft cloth lightly
moistened with a mild detergent solution. Do not use any type
of abrasive pad, scouring powder, or solvent, such as alcohol or
benzine.
Note
Do not remove the tilt-swivel base from the monitor.
• Do not rub, touch, or tap the surface of the screen with sharp or
abrasive items such as a ballpoint pen or screwdriver. This type
of contact may result in a scratched picture tube.
• Clean the screen with a soft cloth. If you use a glass cleaning
liquid, do not use any type of cleaner containing an anti-static
solution or similar additive as this may scratch the screen’s
coating.
Warning on power connection
• Use an appropriate power cord for your local power supply.
Example of plug types:
US
Transportation
for 100 to 120 V AC for 200 to 240 V AC for 240 V AC only
When you transport this monitor for repair or shipment, use the
original carton and packing materials.
• Before disconnecting the power cord, wait at least 30 seconds
after turning off the power to allow the static electricity on the
CRT display surface to discharge.
• After the power has been turned on, the CRT is demagnetized
(degaussed) for a few seconds. This generates a strong
magnetic field around the metal frame, which may affect the
data stored on magnetic tapes and disks near the bezel. Place
magnetic recording equipment, tapes, and disks away from this
monitor.
The equipment should be installed near an easily accessible
electrical outlet.

Workplace Preparation
Step 2:Connect the power cord
Positioning the Monitor
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.
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
Step 3:Turn on the monitor and
computer
Rest
Take regular breaks. Vary your posture, and stand up and stretch
occasionally as prolonged use of computer workstations can be
tiring.
US
First turn on the monitor, then turn on the computer.
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.
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
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.
• Check that the monitor is correctly connected to the computer.
• If NO SIGNAL appears on the screen, try changing the input
board is completely seated in the correct bus slot.
Screen settings
• 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.
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.

Technical Features
Troubleshooting
Before contacting technical support, refer to this section.
Preset and user modes
If thin lines appear on your screen
(damper wires)
When the monitor receives an input signal, it automatically
matches the signal to one of the factory preset modes stored in the
monitor’s memory to provide a high quality picture at the center
For input signals that do not match one of the factory preset
modes, the digital Multiscan technology of this monitor ensures
that a clear picture appears on the screen for any timing in the
monitor’s frequency range (horizontal: 30 – 130 kHz, vertical: 48
– 170 Hz). If the picture is adjusted, the adjustment data is stored
as a user mode and automatically recalled whenever the same
input signal is received.
The visible lines on your screen especially when the background
screen color is light (usually white), are normal for the Trinitron
monitor. This is not a malfunction. These are shadows from the
damper wires used to stabilize the aperture grille. The aperture
grille is the essential element that makes a Trinitron picture tube
unique by allowing more light to reach the screen, resulting in a
brighter, more detailed picture.
Damper wires
Note for Windows users
For Windows users, check your graphics board manual or the
utility program which comes with your graphics board and select
the highest available refresh rate to maximize monitor
performance.

This monitor meets the power-saving guidelines set by VESA and
ENERGY STAR. If no signal is input to the monitor from your
computer, the monitor will automatically reduce power
consumption as shown below.
If there is something wrong with the input signal, one of the
following messages appears on the screen.
If NO SIGNAL appears on section 1
This indicates that no signal is input from the selected video input
connector.
