As an ENERGY STAR Partner our company has determined that this product meets the ENERGY STAR
guidelines for energy efficiency.
WARNING:
To prevent fire or chock hazard, do not expose the monitor to rain or moisture. Dangerously high voltages are
present inside the monitor. Do not open the cabinet. Refer servicing to qualified personnel only.
-4-
PRECAUTIONS
Do not use the monitor near water, e.g. near a bathtub, washbowl, kitchen sink, laundry tub,
Swimming pool or in a wet basement.
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.
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.
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.
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.
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.
Do not overload power strips and extension cords. Overloading can result in fire or electric shock.
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.
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.
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.
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
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.
You may find slightly uneven brightness in the screen depending on the desktop pattern you use.
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.
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.

INTRODUCTION
Scope
This specification defines the requirements for the 17” MICRO-PROCESSOR based Multi-mode
supported high resolution color LCD monitor. This monitor can be directly connected to general 15
pin D-sub VGA connector and eliminates the requirement of optional special display card. It also
supports VESA DPMS power management and plug & play function. There is a build-in stereo
audio amplifier with volume control to drive a pair of speakers.
Description
The LCD monitor is designed with the latest LCD technology to provide a performance oriented product with no
radiation. This will alleviate the growing health concerns. It is also a space saving design, allowing more desktop space,
and comparing to the traditional CRT monitor, it consumes less power and gets less weight in addition MTBF target is
20k hours or more.

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.
2
The DDC2Bis a bidirectional data channel based on the I C 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 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
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.

Power Consumption
The monitor is equipped with a power-management according to the below.
There is a delay of 5s … 7s before the transition from On-state to any power saving state to avoid
unintentionally entering of a power saving stage during display resolution and timing mode changes.
Transition from any power saving state to another can be instantaneous.
The recovery from Off-state requires no manual power on.
