1. Precautions and Notices1.1 Safety Precautions
Although LCD monitors are displays without high voltage as that in the CRTs, the
following precautions still should be take care of.
1)Observe all cautions and safety related notes located inside the display cabinet and onthe display chassis.
2)Operation of these displays outside the cabinet or with the cover removed involves ashock hazard from the display backlights inverter. Work on the display should not be
attempted by anyone who is not thoroughly familiar with precautions necessary when
working on high voltage equipment.
3)Before returning a serviced display to the customer, a thorough safety test must beperformed to verify that the display is safe to operate without danger or shock.
1.2 Product Safety Notice1)Many electrical and mechanical parts in this chassis provide special visual safety
protection. The protection afforded by them cannot necessarily be obtained by using
replacement components rated for higher voltage, wattage, etc.
2)Before replacing any of these components, read the parts list manual carefully. The useof substitute replacement parts, which do not have the same safety characteristics, as
specified in the parts list may create shock, fire or other hazards.
1.3 Service Notes1)When replacing parts or circuit boards, wrap the wires around terminals before
soldering.
2)Keep wires away from high temperature components.3)Keep cable and their shielding in their original position so as to reduce interference.

5. General Connection and ApplicationsProcedures for installing and using this CML171SX LCD monitor are described as
below.
5.1 Connecting the monitor to the computer1)Place the display on a flat, sturdy surface. Choose an area free from excessive heat,
moisture, and sunlight. Avoid possible sources of electromagnetic interference, such as
transformers, motors, and fluorescent lighting.
2)Locate the AC power adapter with attached power cable and then connect the power cableto the power jack on the back of the display. Plug the three-prong power cord into a power
outlet, and plug the other end into the AC power adapter. The three-prong power cord is a
shielded type and is provided as a safety precautions to ensure proper electrical grounding.
Plug the D-SUB 15-pin analog signal cable into the Analog Input port or DVD-D 25 pin
signal cable into the Digital Input pory on the back of the display. Connect the other end of
the signal cable into your computers VGA output port. The assignment of the pins of the
connector is as follows:
