LG FLATRON L2320A User manual

A1
This unit has been engineered and manufactured to ensure your personal
safety, however improper use may result in potential e shock or fire hazards.
In order to allow the proper operation of all safeguards incorporated in this
display, observe the following basic rules for its installation, use, and
servicing.
On Safety
Use only the power cord supplied with the unit. In case you use another power
cord, make sure that it is certified by the applicable national standards if not being
provided by the supplier. If the power cable is faulty in any way, please contact the
manufacturer or the nearest authorized repair service provider for a replacement.
The power supply cord is used as the main disconnection device. Ensure that the
socket-outlet is easily accessible after installation.
Operate the display only from a power source indicated in the specifications of
this manual or listed on the display. If you are not sure what type of power supply
you have in your home, consult with your dealer.
Overloaded AC outlets and extension cords are dangerous. So are frayed power
cords and broken plugs. They may result in a shock or fire hazard. Call your service
technician for replacement.
Do not Open the Display.
There are no user serviceable components inside.
There are Dangerous High Voltages inside, even when the power is OFF.
Contact your dealer if the display is not operating properly.
To Avoid Personal Injury :
Do not place the display on a sloping shelf unless properly secured.
Use only a stand recommended by the manufacturer.
To Prevent Fire or Hazards:
Always turn the display OFF if you leave the room for more than a short period
of time. Never leave the display ON when leaving the house.
Keep children from dropping or pushing objects into the display's cabinet
openings. Some internal parts carry hazardous voltages.
Do not add accessories that have not been designed for this display.
During a lightning storm or when the display is to be left unattended for an
extended period of time, unplug it from the wall outlet.
Do not place objects on top of the media station or cover it. Obstructing
ventilation holes may damage your media station or overheat the machine
causing fire.
Important Precautions

A2
Important Precautions
On Installation
Do not allow anything to rest upon or roll over the power cord, and do not place
the display where the power cord is subject to damage.
Do not use this display near water such as near a bathtub, washbowl, kitchen
sink, laundry tub, in a wet basement, or near a swimming pool.
Displays are provided with ventilation openings in the cabinet to allow the release
of heat generated during operation. If these openings are blocked, built-up heat
can cause failures which may result in a fire hazard. Therefore, NEVER:
Block the bottom ventilation slots by placing the display on a bed, sofa, rug, etc.
Place the display in a built-in enclosure unless proper ventilation is provided.
Cover the openings with cloth or other material.
Place the display near or over a radiator or heat source.
Do not rub or strike the Active Matrix LCD with anything hard as this may scratch,
mar, or damage the Active Matrix LCD permanently.
Do not press the LCD screen with your finger for a long time as this may cause
some afterimages.
Some dot defects may appear as Red, Green or Blue spots on the screen.
However, this will have no impact or effect on the display performance.
If possible, use the recommended resolution to obtain the best image quality for
your LCD display. If used under any mode except the recommended resolution,
some scaled or processed images may appear on the screen. However, this is
characteristic of the fixed-resolution LCD panel.
On Cleaning
Unplug the display before cleaning the face of the display screen.
Use a slightly damp (not wet) cloth. Do not use an aerosol directly on the display
screen because over-spraying may cause electrical shock.
On Repacking
Do not throw away the carton and packing materials. They make an ideal
container in which to transport the unit. When shipping the unit to another
location, repack it in its original material.
* This monitor is not designed for visual display workplace.

About this monitor
Bright Window
This function provides exceptionally adjustable contrast and brightness that can be applied
to any specially sized section of the screen.
Swap
To switch the main-screen and sub-screen in PIP/POP mode.
Spectacle
This function provides different areas of the screen with a varied ratio, so that the ratio at the
central area is close to 4:3 and near the edges it exceeds 16:9. Since most people
concentrate their focus upon the central area of the screen, they do not clearly recognize a
nonlinear expansion of the image near the edges of the display. Therefore a 4:3 image can
fit into the wide screen fairly naturally. However, it should be noted that this function is
useful for TV or motion pictures, but not suitable for a PC environment such as computer
graphics or word processing.
Sleep Timer
You can set a time period after which the AV/DVD/HDTV should switch itself to standby.
Press the key repeatedly to select the number of minutes.
