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 ar e not s ure of t he type of power s upplie d to your home, c onsult 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 electr ician
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 s urges.

! Do not overload power strips and extension cords. Overloa ding 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 personn el.

! To ensure satisfactory operation, use the monitor only with UL listed computers

which have appropriate configured receptacles marked between 100 - 240V AC,
Min. 1.5A.

! The wall socket shall be installed near the equipment and sh all 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 MO NITOR WILL AP PEAR TO BE NO N-FUNCTION AL 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 displa y is completely off.
The displa y is restored by pressing a key on the keybo ard, or clic king the mouse.

USING THE RIGHT POWE R CO RD:

The accessory power cord for the Northern American region is the wall 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 f or connection to power outlet of personal computer:
Please use a cord set consisti ng of a minimum No. 18 AWG, type S JT or SVT three
conductors flexible cord. One end terminates with a gr ounding 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.
