FCC Class B Radio Frequency Interference Statement  
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.  
3. The manufacturer is not responsible for any radio or TV interference  
caused by unauthorized modification to this equipment. It is the  
responsibilities of the user to correct such interference.  
WARNING:  
To prevent fire or shock 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.  
SAFETY: Lamp Disposal  
LAMP(S) INSIDE THIS PRODUCT CONTAIN MERCURY AND MUST BE

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 cart, stand, or table. If the monitor  
falls, it can injure a person and cause serious damage to the appliance.  
Use only a cart or stand recommended by the manufacturer or sold with  
the monitor. If you mount the monitor on a wall or shelf, use 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 lightening storm or when it will not be used for  
long period 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 by 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.  
z
For use only with the attached power adapter (Output 12Vdc) 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 on 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 has been  
displayed for a long time. The monitor will slowly recover from this.

PLUG AND PLAY  
Plug & Play DDC 2B Feature  
This monitor is equipped with VESA DDC 2B 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 DDC 2B is a bidirectional data channel based on the I²C protocol. The  
host can request EDID information over the DDC 2B 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 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 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.
