Precautions
Warning on power connections
• Use the supplied power cord. If you use a different power cord,
be sure that it is compatible with your local power supply.
For the customers in the UK
If you use the monitor in the UK, be sure to use the supplied UK
power cable.
• Before disconnecting the power cord, wait at least 30 seconds
after turning off the power to allow the static electricity on the
screen’s surface to discharge.
• After the power is turned on, the screen is demagnetized
(degaussed) for about 5 seconds. This generates a strong
magnetic field around the screen which may affect data stored
on magnetic tapes and disks placed near the monitor. Be sure to
keep magnetic recording equipment, tapes, and disks away
from the monitor.
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 an electrically charged metal surface
Maintenance
• 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.
• 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 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
benzene.
Transportation
When you transport this monitor for repair or shipment, use the
original carton and packing materials.
Use of the stand
Insert the supplied stand into the groove to adjust the angle of the
monitor. You can use the stand in either the vertical or horizontal
position. If you do not need the stand for this purpose, you can use
it as a convenient CD rack.
The equipment should be installed near an easily accessible
outlet.

Connecting Universal Serial Bus
(USB) compliant peripherals
Your monitor has one upstream USB connector (on the rear
panel) and four downstream USB connectors (two on both the left
and right sides). They provide a fast and easy way to connect USB
compliant peripheral devices (such as keyboards, mice, printers
and scanners) to your computer using a standardized USB cable.
To use your monitor as a hub for your peripheral devices, connect
the USBs as illustrated below.
1 Turn on the monitor and computer.
2 Connect your computer to the square upstream
connector using the supplied USB cable.
For customers using Windows
If a message appears on your screen, follow the on-screen instructions
and select Generic USB Hub as the default setting.
3 Connect your USB compliant peripheral devices to
the rectangular downstream USB connectors.
Notes
• Not all computers and/or operating systems support USB
configurations. Check your computer’s instruction manual to see if you
can connect USB devices.
• In most cases, USB driver software needs to be installed on the host
computer. Refer to the peripheral device’s instruction manual for
further details.
• The monitor functions as a USB hub as long as the monitor is either
“on” or in power saving mode.
• If you connect a keyboard or mouse to the USB connectors and then
boot your computer for the first time, the peripheral devices may not
function. First connect the keyboard and mouse directly to the
computer and set up the USB compliant devices. Then connect them to
this monitor.
• Do not lean on the monitor when plugging in the USB cables. The
monitor may suddenly shift and cause injury.

Technical Features
Preset and user modes
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 of
the screen. (See Appendix 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 monitor’s
frequency range (horizontal: 30 – 96 kHz, vertical: 48 – 120 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.
Note for Windows users
For Windows users, check your video board manual or the utility
program which comes with your graphic board and select the
highest available refresh rate to maximize monitor performance.
Power saving function
This monitor meets the power-saving guidelines set by VESA,
ENERGY STAR, and NUTEK. If no signal is received by the
monitor from the connected computer, the monitor will
automatically reduce power consumption as shown below.
* Figures reflect power consumption when no USB compatible
peripherals are connected to the monitor.
** When your computer enters the “active off” mode, the input signal is
cut and NO INPUT SIGNAL appears on the screen. After 20 seconds,
the monitor enters the power saving mode.
Troubleshooting
Before contacting technical support, refer to this section.
If thin lines appear on your screen
(damper wires)
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.
On-screen messages
If there is something wrong with the input signal, one of the
following messages appears on the screen. To solve the problem,
see “Trouble symptoms and remedies” on page 13.
The input signal condition
OUT OF SCAN RANGE
indicates that the input signal is not supported by the
monitor’s specifications.
NO INPUT SIGNAL
indicates that no signal is being input to the monitor.

some video boards may have a sync pulse that is too narrow for the monitor to sync
correctly.
• Adjust the computer’s refresh rate (vertical frequency) to obtain the best possible picture.
Picture is fuzzy • Adjust the brightness and contrast (page 9).
• Degauss the monitor* (page 11).
• Select CANCEL MOIRE and adjust the moire cancellation effect (page 11).
