WARNING: (FOR FCC CERTIFIED MODELS)
NOTE: this equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment generates, uses and can radiate radio
frequency energy, and if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that interference will not occur in
a particular installation. If this equipment does cause harmful interference to radio or television reception,
Which can be determined by turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
1. Reorient or relocate the receiving antenna.
2. Increase the separation between the equipment and receiver.
3. Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
4. Consult the dealer or an experienced radio/TV technician for help.
NOTICE:
1. The changes or modifications not expressly approved by the party responsible for compliance could
void
the user's authority to operate the equipment.
2. Shielded interface cables and AC power cord, if any, must be used in order to comply with the emission
limits.

modification to this equipment. It is the responsibility of the user to correct such interference.
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.
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.
For use only with the attached power adapter (output 12V DC) which have UL,CSA listed license
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.

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 communication channel is defined
in two levels, DDC2B.
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 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.

"Both" means both files writing together.
"1 TO 4 writer" means 4pcs main boards writing together at the same time.
"Auto" means the PC writing automatically.
"Erase" means procedure erased the former bios of monitor.
When write Acer model bios, if two files used, set up the file properties as fellow:
1. Within 64K option, choose the bios file without "ext";
2. Within 64K~~96K option, choose the bios file with "ext";
3. Then choose "Both";
4. Then choose "Auto";
5. Click , go to write.
Notice: The distinction between "64K" and "64-96K" is from BIOS file name.
Such as:

2. Whether the monitor is "on" state (it can't into factory state, please retry again)
3. Whether the cord connections is ok?
4. Whether PC LPL is ok?
5. Whether the main board of Monitor is good?
(After checking above items, you should search for more supports from related dept if it has not worked yet.)
Warning!!
Don't choose the error position of BIOS file between "64K" and "64~~94".
If do, it works but brings out the Chaos and abnormal for OSD.
