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 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 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 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.
! 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 by 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 appropriate configured receptacles marked
between 100 - 240V AC, Min. 5A.
! The wall socket shall be installed near the equipment and shall be easily
accessible.
! For use only with power adaptor manufacturer by CHI SAM
ELECTRONIC , model CH-1205. NOTES
•
Do not install the monitor in a location near heat sources such as
radiators or air ducts, or in a place subject to direct sunlight, or excessive
dust or mechanical vibration or shock.
PRECAUTIONS (cont)

LM914
•
•
•
Save the original shipping carton and packing materials, as they will come
in handy if you ever have to ship your monitor.
For maximum protection, repackage your monitor as it was originally
packed at the factory.
To keep the monitor looking new, periodically clean it with a soft cloth.
Stubborn stains may be removed with a cloth lightly dampened with a mild
detergent solution. Never use strong solvents such as thinner, benzene,
or abrasive cleaners, since these will damage the cabinet. As a safety
precaution, always unplug the monitor before cleaning it.

PLUG AND PLAY
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 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/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.
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.
