    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

    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.

    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 monitors

    internal power supply consumption. After the video input signal is restored, full power is restored and thedisplay 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.
