and vertical frequency range of this monitor. See the specifications
for this information.

A10
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 three DDC 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.

A11
Audio Features
A major feature of this monitor is its built-in audio system. This
conveniently integrates a stereo audio amplifier and speakers without
taking up any more space. Because the monitor is designed like this,
you can easily upgrade to audio capable multimedia applications by
attaching your PC with sound card to the back of this monitor. It will
result in significantly less cabling and space requirements.
Audio Connections
Use the supplied cable to attach to the rear of the monitor (AUDIO IN)
and to the sound card in your PC (line out). The cable will carry both
left and right channel signals in one wire. Make sure when you use
the PC to turn up the volume of the sound card all the way.
