Introduction
Congratulations on your purchase of the MultiSync A500/A700 colour
Monitor!
The MultiSync A500/A700 monitor includes Microsoft’s Plug and Play,
NEC’s ErgoDesign properties, the On Screen Manager (OSM), as well
as all the unique features you expect from MultiSync Monitors.
The MultiSync technology provides you with automatic compatibility
with multiple operating platforms and a vast array of graphics standards
allowing resolution upgrades without upgrading the monitor.
The MultiSync A500/A700 monitor strictly follows ErgoDesign
guidelines featuring enhanced human ergonomics (human and earth
condition). The goal of ErgoDesign is to maximise the comfort and
productivity of the end user. ErgoDesign parallels the strict European
standards of power management and reduced emissions. In addition our
monitor is designed to be recyclable.
Screen Technology
The OptiClear Surface of the A500/A700 CRT dramatically reduces the
reflection of ambient illumination and glare resulting in greatly
improved user comfort and productivity. This multilayered screen
coating increases the contrast without sacrificing the focus level, clarity
or brightness.
A 0.28 mm dot pitch in conjunction with the Invar Shadow Mask
increases the clarity and displays greater detail. Good clarity allows
your eyes to flow over the screen image and more easily view the
on-screen information.
The flat square CRT technology reduces image distortion and glare.
Plug and Play
Plug and Play is the new Microsoft® solution with Windows® 95 to
provide automatic peripheral connections without confusing and time-
consuming setup. When used with a Plug and Play compatible system
and video card, the MultiSync A500/A700 monitor automatically tells the
Introduction E - 1

system its identification and capabilities. The system will then select its
highest resolution and refresh rate to take advantage of your MultiSync
monitor.
ErgoDesign
The MultiSync ErgoDesign features enhance human ergonomics
(human and earth conditions). MultiSync monitor’s ErgoDesign will
improve the working environment, protect the health of the user and
save money. ErgoDesign parallels the strict European standards of
power management and reduced emissions:
–automatic display power-down (also known as NUTEK
specification 803299)
–emission characteristics (stricter than those referred to as
reduced electromagnetic fields as recommended by MPR II and
for JC-1736VMB-1/JC-1736VMR also by TCO)
–safety (EN 60950)
MultiSync monitors comply with these standards by offering IPM
System power management and Reduced Magnetic Field technology.
Power Manager
IPM (Intelligent Power Manager) System is an innovative power-saving
utility that complies with both the EPA’s Energy Star requirements and
Europe’s TCO NUTEK’s power management requirements. Energy Star
products use less than 30 watts when in the main power saving mode. The
NUTEK specification 803299 requires automatic power down to less than
30 watts in the suspend mode and less than 8 watts in the off mode.
When in the maximum power-down mode, the MultiSync A500/A700
monitor will consume less than 10% of the total power down under normal
operation. This innovation adds up to more than 90% energy savings, longer
monitor life, environmental protection, reduced emissions and reduced air
conditioning costs of the work environment. The IPM System increases the
monitor’s life and saves energy and costs by powering down when not in use.
MultiSync monitors follow the Video Electronics Standard Association
(VESA) approved DPMS power-down signalling method. VESA’s Display
E - 2 Introduction

Power Management Signalling (DPMS) method, which is endorsed by
the EPA, is the power-down process a system should use to
communicate to the monitor to save power. Power-down functions can
be utilised only with an Energy Star system or video card which adheres
to the VESA DPMS standard. By using the monitor’s horizontal and
vertical SYNC signals, the monitor can be prompted into the different
IPM modes. The following is the description of the LED indicator for
the IPM power-saving modes:
Mode LED Indicator Power Saving
On Green None
Stand By Green Minimum (Quickest Recovery)
Suspend Yellow Moderate (< 15 Watts, Moderate
Recovery)
Off (IPM Mode) Orange Maximum (< 8 Watts (A500)/
< 5 Watts (A700), Slow Recovery)
Off (Power
Switch, Off) No Light No Power Used (Fully Off)
Reduced Emissions
The A500/A700 monitor incorporates Reduced Magnetic Field technology
designed to reduce magnetic and alternating electric field emissions and static
electricity. NEC’s monitors follow the strictest magnetic field, alternating
electric field, and electrostatic recommendations of the Swedish Board for
Technical Accreditation, or SWEDAC (previously known as MPR, National
Board for Measurement and Testing). The JC-1736VMB-1/JC-1736VMR
follow the recommendations of the TCO which specify maximum
recommended values of electric and magnetic field.
Introduction E - 3

Multiple Frequency Technology
Multiple Frequency Technology automatically adjusts the monitor to the
video card’s scanning frequency, displaying the resolution you desire.
The MultiSync A500/A700 color monitor also supports multiple
operating platforms such as PC compatible, Macintosh family and
workstation systems.
Increased refresh rates at all resolutions provide a flicker-free image.
The clearer image is easier on your eyes and extends your viewing time.
A wide range of graphics standards of PC and Macintosh computers,
including VESA standards, is supported by the MultiSync A500/A700
color monitor including:
–640 x 480: 60 - 120 Hz
