Section 1 Introduction

The monitor is a multiple frequency high resolution color monitor for IBM
compatible, Macintosh family and workstation systems. The monitor is
equipped with microprocessor based intelligence and multiple frequency scan­ning capability, allowing it to provide maximum compatibility for various
kinds of graphic system hardwares.

The monitor is designed with the latest screen technology including a 0.25mm
High Contrast CRT to display crisp text and vivid color graphics with max.
resolution up to 1600 x 1200, and supports VESA 75Hz modes to provide flicker­free picture. The full function digital control and On-Screen Display system
provides easy adjustment of image geometry and color for different display modes
with the precision of a fixed frequency monitor.

The design of the monitor is also ergonomics concerned, in addition to the
friendly controls and user comfort features, the emission level of electric and
magnetic field is kept low to meet the Swedish MPR II or TCO standard.

The monitor is also equipped with energy saving function, it is compatible
with VESA power saving proposal, the lowest power consumption is less
than 8 W.

Furthermore, the monitor has a built-in USB (Universal Series Bus) hub.
Please refer to the "USB Kit Content" USB hub use information.

Ergonomics Concerned

• Electric and magnetic field emission are kept low to meet the Swed­ish MPR II or TCO standard.

• Front user controls allow easy access and comfort for user to adjust the
screen image to individual preference.

• Horizontal and vertical fullscan capability allows user to use the entire
screen area in most resolutions.

• A tilt/swivel base for horizontal and vertical adjustments provides the
optimum viewing angle.

Instant Power Saving Solutions

• The monitor is compatible with VESA DPMS (Display Power Manage­ment Signalings), providing four power saving modes by detecting hori­zontal and vertical sync signals.

• The monitor consumes 80 W to 155 W depending on the display content
in normal operation, when the power saving mode is activated, it con­sumes less than 15 W in "stand-by" mode, less than 15 W in "suspend"
mode and less than 8 W in "off" mode.

1.5 Recommended Use of the Monitor

When setting up and using the monitor, pay special attention to the following
for optimum performance.

• Do not use your monitor against a bright background or where sunlight or
other light sources will shine directly on the screen.

• The monitor should be placed just below eye level (10°~15°) for opti­mum viewing.

• Set the monitor's brightness to match the ambient room light.

• For optimum focus, the contrast control should not be set to the maxi­mum unless the input signal level is extremely low. Also, the brightness
control should be set to a point where the overall background area just
begins to disappear.

• Allow adequate ventilation around the monitor so that the heat from the
monitor can properly dissipate.

• Neither the monitor itself, nor any other heavy object, should rest on the
power cord. Damage to a power cord can cause fire or electrical shock.

• Keep the monitor away from high capacity transformers, electrical motors,
and other strong magnetic field.

• Your monitor should not be used in damp, dusty, or dirty areas.

• Handle your monitor with care when transporting it.

!

CAUTION

• Do not scrap or knock the surface of CRT with a pen, a
screwdriver and so on.

• Clean the CRT surface with a lint-free, nonabrasive,
soft cloth, and should not use the solution or glass
cleaner containing corpuscels like an abrasive, alcohol
and an alkaline solution.
