Use of the Tilt-Swivel  
Precautions  
This monitor can be adjusted within the angles shown below. To  
find the center of the monitors turning radius, align the center of  
the monitors 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 screens  
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 monitors 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  
signal (page 6), and confirm that your computers graphics  
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 computers 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  
monitors memory to provide a high quality picture at the center  
of the screen. (See page 20 for a list of the factory preset modes.)  
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  
monitors 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.
