Hinweise

• Aus ergonomischen Gründen wird empfohlen, die
Grundfarbe Blau nicht auf dunklem Untergrund zu verwenden
(schlechte Erkennbarkeit, Augenbelastung bei zu geringem
Zeichenkontrast).

• Aus ergonomischen Gründen (flimmern) sollten nur
Darstellungen bei Vertikalfrequenzen ab 70 Hz (ohne
Zeilensprung) verwendet werden.

• Die Konvergenz des Bildes kann sich auf Grund des
Magnetfeldes am Ort der Aufstellung aus der korrekten
Grundeinstellung verändern. Zur Korrektur empfiehlt es sich
deshalb, die Regler an der Frontseite für Konvergenz so
einzustellen, daß die getrennt sichtbaren Farblinien für Rot,
Grün und Blau bei z.B. der Darstellung eines Buchstabens
zur Deckung (Konvergenz) gelangen.
Siehe hierzu auch die Erklärungen zu Konvergenz.

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 U.S.A.

If you do not use the appropriate cord, this monitor will not
conform to mandatory FCC standards.

Example of plug types

Use of the tilt-swivel

This monitor can be adjusted within the angles shown below. To
find the center of the mon itor’ s turnin g radius, a lign the ce nter of
the monitor’s screen with the centering dots on the stand.
Hold the monitor at the bott om with bo th ha nd s whe n yo u tu rn it
horizontally or vertically. Be careful not to pinch your fingers at
the back of the monitor when you tilt the monitor up vertically.

for 100 to 120 V AC

• Before disconnecting the power cord, wait at least 30 seconds

after turning off the power to allow the static elec tricity 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.

The equipment should be in stalled near an easily accessibl e
outlet.

for 200 to 240 V AC

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 volta g e po w er 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 t ype 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 su ch as a ballpoint pe n or screwdrive r. This type
of contact may result in a scratched picture tube.

• Clean the cabin e t, pane l and co nt rols wi th a soft cloth ligh tly

moistened with a mild detergent solution. Do not use any type
of abrasive pa d, sc ouring powder or solv ent, s uch as a lcohol o r
benzene.

Transportation

When you transport this monitor for repair or shipment, use the
original carton and packing materials.

• Before using this feature, the monitor must be in normal ope ra tion
mode (green power indicator on) for at least 30 minutes. If the monitor
goes into power saving mode, you m ust ret urn t he monitor to normal
operation mode and wa it for 30 minutes for the monitor to be ready.
You may need to adjust your computer’s power saving settings to keep

shown in the menu using your computer. If the input signal
matches one of this monitor’s factory preset mode s, the resolution
and refresh rate of the current input signal ar e displayed.

• The monitor may gradually lose its ability to perform this function due
to the natural aging of the pic ture tube.

Technical Features

Damper wires

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.
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 – 107 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.

(See Appendix for a list of the factory preset modes.)

Troubleshooting

Before contacting technical support, refer to this section.

If thin lines appear on your screen
(damper wires)

The lines you are experiencing on your screen are normal for the
Trinitron monitor and are not a malfunction. These are shadows
from the damper wires used to stabilize the aperture grille and are
most noticeable when the screen’s background is light (usual ly
white). 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.
