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
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.

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.
Do not use the monitor near water, e.g. near a bathtub,
washbowl, kitchen sink, laundry tub, swimming pool or in a wet
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.
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.
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
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
To ensure satisfactory operation, use the monitor only with UL
listed computers which have appropriate configured receptacles
marked between 100 - 240V AC, Min. 2.5A.
The wall socket shall be installed near the equipment and shall
be easily accessible.
Attention: Disconnect the power cord to stop the power supply
to the monitor.

Plug & Play DDC1/2B Feature
This monitor is equipped with VESA DDC1/2B 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 communication channel is defined in two levels,
DDC1 and DDC2B.
The DDC1 is a unidirectional data channel from the display to the
host that continuously transmits EDID information. The DDC2B is
a bidirectional data channel based on the I²C protocol. The host
can request EDID information over the DDC2B channel.
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.
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
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.

Power Source:
1. Make sure the power cord is the correct type that required in
your area.
2. This monitor has a universal power supply that allows operation
in either 100/120V AC or 220/240V AC voltage area (No user
adjustment is required).
3. Connect the power cord into your monitor’s power input socket,
and then plug the other end into a 3-pin AC power outlet. The
power cord may be connected to either a wall power outlet or
the power outlet socket on your PC, depending on the type of
power cord supplied with your monitor.
Connecting the Video Cable: the monitor comes with a built-in
video cable. Plug the signal cables 15-pin connector into the
