shock or fire hazard. In order not to defeat the safeguards
incorporated in this monitor, observe the following basic rules for its
installation, use, and servicing. Also follow all warnings and
instructions marked directly on your monitor.
On safety
1. 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.
2. If the power cable is faulty in any way, please contact the
manufacturer or the nearest authorized repair service provider for a
replacement.
3. Operate the monitor only from a power source indicated in the
specifications of this manual or listed on the monitor. If you are not
sure what type of power supply you have in your home, consult
with your dealer.
4. 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.
5. DO NOT OPEN THE MONITOR. There are no user serviceable
components inside. There are Dangerous High Voltages inside,
even when the power is OFF. Contact your dealer if the monitor is

Power Management System
When used in conjunction with a PC having power saving circuitry, or
a PC running screen blanking software this monitor automatically
reduces its power consumption when the computer is not in use.The
monitor has power-saving states, indicated by the light-emitting diode
(LED) on the front panel.These power-saving states exceed the
Environmental Protection Agency (EPA) Energy Star requirements
using the methodology for Display Power Management Signals(DPMS).
Developed by the Video Electronics Standards Association(VESA).
Low Radiation Compliance (MPR II)
This monitor meets one of the strictest guidelines available today for
low radiation emissions, offering the user extra shielding and an anti-
static screen coating. These guidelines, set forth by a government
agency in Sweden, limits the amount of emission allowed in the
Extremely Low Frequency (ELF) and Very Low Frequency (VLF)
electromagnetic range.
DDC (Display Data Channel)
DDC is a communication channel over which the monitor
automatically informs the host system(PC) about its capabilities.This
monitor has DDC2B function; DDC2B carry out uni-directional
communication between PC and monitor. Under these situations, the
PC sends display data to the monitor but not commands to control the
monitor servings.
NOTE : PC must support DDC functions to do this.
Some older computer systems are not compatible with the
DDC standard. If your monitor is displaying a monochrome
image or the wrong resolution, need to change with a DDC
compatible VGA card.

A10
General Operation
After following the installation instructions and getting familiar with the
controls, you are ready to operate the monitor.
1. Turn on the monitor, PC and other peripherals you plan to use.
2. After the PC has booted (powered up and finished self-testing),
enter a software application that uses the full screen display.
3. While looking at the image on the screen, adjust the controls for
the image size, centering, brightness and contrast levels you
prefer.
4. This monitor is an auto scanning monitor, capable of synchronizing
with a variety of video standards automatically. The Scanning
Mode Table below indicates the resolution, as well as the horizontal
and vertical refresh rates, of some of the modes that this monitor
can match to the output of your PC's graphics card.
Other resolutions and standards can also be synchronized and
displays on this monitor as long as they are within the horizontal
and vertical frequency range of this monitor. See the specifications
for this information.
