Connection To Your Personal Computer

For the PC:

Your system has one of two configurations:

– the video controller is built into the computer
– the video controller is in the form of a display card

(sometimes referred to as the graphics card, video adapter or
graphics board)

Both configurations have a video connector (or a CRT PORT on
laptop computers). If you are not sure which port is the video
connector, please consult your computer or display card manual.

For the Mac:

You will connect your MultiSync® P
to your Macintosh computer:

– On-board video port
– NuBus, PDS or PCI display card

Both configurations should have the same style video connec­tor. If you are not sure which port is the video connector,
please consult your computer or display card manual.

To attach the MultiSync P
system, follow these instructions:

1. Turn off the power to your computer and MultiSync monitor.

2. If necessary, install the display card. For more information, refer
to the display card manual.

If you are using a BNC cable, continue to Step 3. If you are using
the MultiCable connection system, please skip to Step 4.

3. Make sure the BNC/D-SUB Switch on the front of the monitor
is set to the BNC (out) position. Connect the D-SUB (or the
appropriate connector) end of the video cable supplied with
the display card to the connector of the display card. Connect
the red BNC cable to the BNC connector on the monitor
labeled “R”. The green BNC cable should be connected to the
BNC connector on the monitor labeled “G”. The blue BNC
cable should be connected to the BNC connector on the
monitor labeled “B”. If you have a fourth BNC connector
(composite Sync), connect it to the BNC connector on the
monitor labeled “HS/CS”. If you have a fifth BNC connector
(vertical Sync), connect it to the BNC connector on the monitor
labeled “VS”. Please skip to Step 5.

ErgoDesign® Features

ErgoDesign features enhance human ergonomics (human and
earth conditions), which will improve the working environment,
protect the health of the user and save money. ErgoDesign
features parallel the strict European standards of power manage­ment and reduced emissions and the requirements laid down in
the MPR II.

Power Manager

IPM™ (Intelligent Power Manager) System is an innovative
power-saving feature that complies with both the EPA’s Energy
Star requirements and Europe’s TCO NUTEK 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.

7

Introduction

When in the maximum power-down mode, the MultiSync
P

750

monitor will consume approximately 10% of the total

power drawn under normal operation, which follows the Video
Electronics Standard Association (VESA) approved DPMS
power-down signaling method. This innovation adds up to 90%
energy savings, longer monitor life, environmental protection,
reduced emissions and reduced air conditioning costs of the
work environment.

Reduced Emissions

electric field emissions and static electricity. NEC MultiSync
monitors follow the strictest magnetic field, alternating electric
field and electro-static recommendations of the Swedish Board
for Technical Accreditation, or SWEDAC (previously known as
MPR, National Board for Measurement and Testing) and TCO
(excluding alternating electric fields) which specify maximum
recommended values of electric and magnetic fields.

MultiCable™ Connection System

The MultiCable Connection System on the MultiSync
monitor provides convenient compatibility with a wide variety of

P

750

operating platforms or systems. The MultiCable connection
system has two types of connectors: a 15-pin mini D-SUB
connector for connection to NEC and other PC compatible
systems and a 15-pin D-SUB connector for Macintosh systems.
After assembling the cable to your video connector or display
card, attach the other end to the appropriate connector on the

P

back of the MultiSync

monitor.

OSM™ (On-Screen Manager) Controls

Now, OSM (On-Screen Manager) Controls have made the
MultiSync monitor’s Advanced Digital Control™ System easier to
use by providing menus on screen. A touch of the up-front
buttons turns on the OSM controls, allowing you to easily
navigate through menus and adjust controls.

OSM controls allow you to control features such as Brightness,
Contrast, Size, Position, Geometry and other OSM utilities.
User adjustments are saved automatically when you change
menus. Controls can be reset to factory settings by pressing the

inside and opening or removing covers may expose you to danger­ous shock hazards or other risks. Refer all servicing to qualified
service personnel.

• Allow adequate ventilation around the monitor so that heat can

properly dissipate. Do not block ventilated openings or place the
monitor near a radiator or other heat sources. Do not put anything
on top of monitor.

• Do not spill any liquids into the cabinet or use your monitor near water.

• Do not insert objects of any kind into the cabinet slots, as they may

touch dangerous voltage points, which can be harmful or fatal or
may cause electric shock, fire or equipment failure.

• Do not place any heavy objects on the power cord. Damage to the

cord may cause shock or fire.

• Do not place this product on a sloping or unstable cart, stand or

table, as the monitor may fall, causing serious damage to the
monitor.

®

P750™ COLOR MONITOR:

There are no user serviceable parts

• Keep the monitor away from high capacity transformers, electric

motors and other devices such as external speakers or fans, which
may create strong magnetic fields.

• If possible, position the monitor so that it is facing the east to minimize

the effects of the earth’s magnetic field.

• Changing the direction of the monitor while it is powered on may

cause image discoloration. To correct this, turn the monitor off for 20
minutes before powering it back on.

• The power cable connector is the primary means of detaching the

system from the power supply. The monitor should be installed close
to a power outlet which is easily accessible.

• Handle with care when transporting. Save packaging for transporting.

Immediately unplug your monitor from the wall outlet and
refer servicing to qualified service personnel under the
following conditions:

• When the power supply cord or plug is damaged.

• If liquid has been spilled, or objects have fallen into the monitor.

• If the monitor has been exposed to rain or water.

• If the monitor has been dropped or the cabinet damaged.

• If the monitor does not operate normally by following operating

instructions.

CORRECT PLACEMENT AND ADJUSTMENT OF THE MONITOR

CAN REDUCE EYE, SHOULDER AND NECK FATIGUE. CHECK THE

FOLLOWING WHEN YOU POSITION THE MONITOR:

• Adjust the monitor height so that the top of the screen is at or slightly

below eye level. Your eyes should look slightly downward when
viewing the middle of the screen.

• Position your monitor no closer than 12 inches and no further away

than 28 inches from your eyes. The optimal distance is 18 inches.

• Rest your eyes periodically by focusing on an object at least 20 feet

away. Blink often.

• Position the monitor at a 90° angle to windows and other light

sources to minimize glare and reflections. Adjust the monitor tilt so
that ceiling lights do not reflect on your screen.

• If reflected light makes it hard for you to see your screen, use an anti-

glare filter.

• Clean your monitor regularly. Use a lint-free, non-abrasive cloth and
