Warning:

To prevent fire or shock hazard, do not expose the monitor to rain or moisture. Dangerous high voltages are

present inside the monitor. Do not open the cabinet. Refer servicing to qualified personnel only.

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 manufacturer or sold

with the monitor. If you mount the monitor on a wall or shelf, uses a mounting kit approved by the manufacturer

and follow the kit instructions.

z Slots and openings in the back and bottom of the cabinet are 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. 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 on 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.

How To Optimize The DOS-Mode

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 DDC2B is a bi-directional data channel based on the I²C protocol. The host can request EDID information over

the 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 signals 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 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 volts 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 cord needs to use VDE 0602, 0625, 0821 approval power cord in European counties.

P.S: The 1N4148 Vf=0.7V~1V can't meet

LDO spec. The BAT42, Vf is OK but the

If=200mA(forward current) can not

meet current spec.

D704(SSM12L) Vf=0.38V and If=1A.

So when system power on, the

system loading is about 400mA

(3.3V is about 200mA and 1.8V is

about 200mA), So D35 changed

from 1N4148(or BAT42) to

SSM12L(schottky diode).
