Introduction
Thank you for purchasing a high resolution monitor. It will give you
high resolution performance and convenient reliable operation in a
variety of video operating modes.
The monitor is a 21 inches (20 inches viewable ) intelligent,
microprocessor based monitor compatible with most analog RGB (Red,
Green, Blue) display standards, including IBM PC¨, PS/2¨, Apple¨,
Macintosh¨, Centris¨, Quadra¨, and Macintosh II family.
USB (Universal Serial Bus) ports at the back of the monitor are prepared
for the USB cable and hub. You can easily and flexibly connect USB-
designed devices-such as a mouse, keyboard or printer- to the monitor
for true Plug and Play function.
The monitor provides crisp text and vivid color graphics with VGA,
SVGA, XGA, and VESA Ergonomic modes (non-interlaced), and most
Macintosh compatible color video cards when used with the appropriate
adaptor. The monitor's wide compatibility makes it possible to upgrade
video cards or software without purchasing a new monitor.
Digitally controlled auto-scanning is done with the micro-processor for
horizontal scan frequencies between 30 and 115kHz, and vertical scan
frequencies between 50-200Hz. The microprocessor-based intelligence
allows the monitor to operate in each frequency mode with the
precision of a fixed frequency monitor.
The microprocessor-based digital controls allow you to adjust
conveniently a variety of image controls by using the OSD (On Screen
Display).
This monitor is capable of producing a maximum horizontal resolution of
1600 dots and a maximum vertical resolution of 1200 lines. It is well
suited for CAD work and sophisticated windowing environments.
For low cost of monitor operation, this monitor is certified as meeting
the EPA Energy Star requirements, and utilizes the VESA Display Power
Management Signalling (DPMS) protocol for power saving during non-
use periods.

Introduction
On Safety
Important Precautions
This unit has been engineered and manufactured to assure your
personal safety, but improper use can result in potential electrical
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.
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.
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.
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 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 not operating properly.
To Avoid Personal Injury :
Do not place the monitor on a sloping shelf unless properly secured.
Use only a stand recommended by the manufacturer.
Do not try to roll a stand with small casters across thresholds or deep
pile carpets.
To Prevent Fire or Hazards:
Always turn the monitor OFF if you leave the room for more than a
short period of time. Never leave the monitor ON when leaving the
house.
Keep children from dropping or pushing objects into the monitor's
cabinet openings. Some internal parts carry hazardous voltages.

On Repacking
Important Precautions
Do not add accessories that have not been designed for this monitor.
During a lightning storm or when the monitor is to be left unattended
for an extended period of time, unplug it from the wall outlet.
Do not bring magnetic devices such as magnets or motors near the
picture tube.
Do not allow anything to rest upon or roll over the power cord, and do not
place the monitor where the power cord is subject to damage.
Do not use this monitor near water such as near a bathtub, washbowl,
kitchen sink, laundry tub, in a wet basement, or near a swimming pool.
Monitors 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 monitor on a bed,
sofa, rug, etc.
Place the monitor in a built-in enclosure unless proper ventilation is
provided.
Cover the openings with cloth or other material.
Place the monitor near or over a radiator or heat source.
Unplug the monitor before cleaning the face of the picture tube.
Use a slightly damp (not wet) cloth. Do not use an aerosol directly on
the picture tube because overspray may cause electrical shock.
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.

USB connection
Making use of USB (Universal Serial Bus) Feature
USB (Universal Serial Bus) is an innovation in connecting your different
desktop peripherals conveniently to your computer. By using the USB,
you will be able to connect your mouse, keyboard, printer, and other
peripherals to your monitor instead of having to connect them to your
computer. This will give you greater flexibility in setting up your system.
USB allows you to connect chain up to 120 devices on a single USB port,
and you can “hot” plug (attach them while the computer is running) or
unplug them while maintaining Plug and Plug auto detection and
configuration. This monitor has an integrated self-powered USB hub,
allowing up to 4 other USB devices to be attached it.
1. Connect the upstream port of the monitor to the downstream port of
the USB compliant PC or another hub using the USB cable (Computer
must have a USB port).
2. Connect the USB compliant peripherals to the downstream ports of
the monitor.
