PRECAUTIONS

z Do not use the monitor near water, e.g. near a bathtub, washbowl, kitchen sink, laundry tub,

Swimming pool or in a wet basement.

z Do not place the monitor on an unstable trolley, stand, or table. If the monitor falls, it can injure a person and

cause serious damage to the appliance. Use only a trolley or stand recommended by the manufacture or sold

with the monitor. If you mount the monitor on a wall or shelf, use a mounting kit approved by the manufacture and

follow the kit instructions.

z Slots and openings in the back and bottom of the cabinet area provided for ventilation. To ensure reliable

operation of the monitor and to protect it from overheating, be sure these openings are not blocked or covered.

Do not place the monitor on a bed, sofa, rug or similar surface. Do not place the monitor near or over a radiator

or heat register. Do not place the monitor in a bookcase or cabinet unless proper ventilation is provided.

z The monitor should be operated only from the type of power source indicated on the label. If you are not sure of

the type of power supplied to your home, consult your dealer or local power company.

z The monitor is equipped with a three-pronged grounded plug, a plug with a third (grounding) pin. This plug will fit

only into a grounded power outlet as a safety feature. If your outlet does not accommodate the three-wire plug,

have an electrician install the correct outlet, or use an adapter to ground the appliance safely. Do not defeat the

safety purpose of the grounded plug.

z Unplug the unit during a lightning storm or when it will not be used for long periods of time. This will protect the

monitor from damage due to power surges.

z Do not overload power strips and extension cords. Overloading can result in fire or electric shock.

z Never push any object into the slot on the monitor cabinet. It could short circuit parts causing a fire or electric

shock. Never spill liquids on the monitor.

z Do not attempt to service the monitor yourself; opening or removing covers can expose you to dangerous

voltages and other hazards. Please refer all servicing to qualified service personnel.

z To ensure satisfactory operation, use the monitor only with UL listed computers which have appropriate

configured receptacles marked between 100-240V AC, Min. 3.5A.

z The wall socket shall be installed near the equipment and shall be easily accessible.

SPECIAL NOTES ON LCD MONITORS

The following symptoms are normal with LCD monitor and do not indicate a problem.

NOTES

z Due to the nature of the fluorescent light, the screen may flicker during initial use. Turn off the Power Switch and

then turn it on again to make sure the flicker disappears.

z You may find slightly uneven brightness in the screen depending on the desktop pattern you use.

z The LCD screen has effective pixels of 99.99% or more. It may include blemishes of 0.01% or less such as a

missing pixel or a pixel lit all of the time.

z Due to the nature of the LCD screen, an afterimage of the previous screen may remain after switching the image,

when the same image is displayed for hours. In this case, the screen is recovered slowly by changing the image or

turning off the Power Switch for hours.

♦ One maximum value of three estimated values.
♦ For this test ,an LMD(Light Measurement Device)is needed with adequate response time

to track any visible rate flicker component and with a voltage level output proportional
To luminance intensity.

♦ Test Pattern: For dot inversion Driving(Gray levels of foreground dots on the test panel

Are G22,G32,and G45)

- 14 -

♦ Test Point :Center point of the display area

Note 8) Definition of Crosstalk (Refer to the VESA STD)

The calculation for shadowing is made from the 2 luminance measurements Gbkg and Lsh,
as follows:

Lmax -Lmin
C

T

=  x100 %

Lmin

Where Lmax is the larger value of Gbkg or Lsh , and Lmin is the smaller of the two.

♦ To determine background and foreground levels (colors),first set the background to any

gray scale or color level suitable for shadowing determination.(Note that it may take
several iterations of adjusting background level and box levels to determine the proper
value for the background .Next display the box levels to determine the proper value for the
background level. Look for shadowing in any direction from box E. Independently vary the
gray level (or color) of the background and box E until the worst case shadowing is
observed. This defines the background (Gbkg) and foreground (Gfg) levels to be
maintained for the remainder of the test.

♦ One point only (the target) will be measured. To determine that point proceed as follows
Using the background and foreground gray levels of step1 (Gbkg and Gfg). Turn on each

box at a time. Look for the case with the worst shadowing. The box causing the worst case
is the shadowing source, or Bsrc. Use Bsrc and the box opposite from it that lies directly in
the shadow path. That is the target box, or Btgt. Note that box Eight be either Bsrc or Btgt,
depending on the shadowing conditions, but typically Bsrc and Btgt will be a pair of

- 15 -

opposite boxes, A&C or B&D. Btgt will only be displayed for aligning the LMD. It will be
turned off for the actual measurement.

♦ The target box point (Btgt) will be measured with the source box (Bsrc) turned on then off.

(Btgt is for alignment purpose only) Display the background only at level Gbkg. Display
Btgt determined in step 2 above. Using the correct distance, angle, and measurement
aperture, align the LMD to the center of the Btgt. Turn off Btgt. With Gbkg set to its
proper level, measure the luminance (or color). Next,turn on the source box Bsrc. Again
measure at the center point of Btgt (without Btgt present.). In this case the LMD will be
measuring the shadowing level, Lsh.

Plug and play

Plug & play DDC2B feature

This monitor is equipped with VESA DDC2B capabilities according to the VESA DDC STANDARD. It allows the monitor

to inform the host system of its identity and, depending on the level of DDC used, communicate additional information

about its display capabilities. The communication channel is defined in two levels, DDC2B.

The DDC2Bis a bidirectional data channel based on the I

DDC2B channel.

THIS MONITOR WILL APPEAR TO BE NON-FUNCTIONAL IF THERE IS NO VIDEO INPUT SIGNAL. IN ORDER

FOR THIS MONITOR TO OPERATE PROPERLY, THERE MUST BE A VIDEO INPUT SIGNAL.

This monitor meets the Green monitor standards as set by the Video Electronics Standards Association(VESA) and/or

the United States Environmental Protection Agency (EPA) and The Swedish Confederation Employees (NUTEK). This

feature is designed to conserve electrical energy by reducing power consumption when there is no video-input signal

present. When there is no video input signal this monitor, following a time-out period, will automatically switch to an

OFF mode. This reduces the monitor’s internal power supply consumption. After the video input signal is restored, full

2

C protocol. The host can request EDID information over the

power is restored and the display is automatically redrawn. The appearance is similar to a “Screen Saver” feature

except the display is completely off. The display is restored by pressing a key on the keyboard, or clicking the mouse.

Using The Right Power Cord

The accessory power cord for the Northern American region is the wallet plug with NEMA 5-15 style and is UL listed

and CSA labeled. The voltage rating for the power cord shall be 125 volt AC.

Supplied with units intended for connection to power outlet of personal computer: Please use a cord set consisting of a

minimum No. 18 AWG, type SJT or SVT three conductors flexible cord. One end terminates with a grounding type

attachment plug, rated 10A, 250V,CEE-22 male configuration. The other end terminates with a molded-on type

connector body, rated 10A, 250V, having standard CEE-22 female configuration.

Please note that power supply card needs to use VDE 0602, 0625, 0821 approval power cord in European counties.
