The following features are provided by the Colour Monitor.
Sharpest Focus and Highest Contrast
Flat screen Enhanced Dot Pitch (EDP) CRT with anti-glare, dynamic focus circuit, dark glass, and
an INVAR shadow mask gives the sharpest focus and highest contrast to minimize eye fatigue.
Wide-range Multi-Scanning
Automatic scanning and automatic adjustment to conform with a wide range of scanning frequencies
and user requirements.
Digital Picture Control Function
Position, size, rotation, pincushion, trapezoid, right pincushion and right trapezoid are adjustable by
digital controls.
Geometry setting can be stored for different HN frequencies. Microprocessor-based preset
functions can store 26 sets of geometry settings including the standard factory settings.
Digital Colour Control Function
Red, green, and blue colour balance is adjustable by digital control.
An adjusted colour setting can be stored and recalled by the colour select button.
Power Saving System
The Environmental Protection Agency (EPA) has established a voluntary program by which
manufacturers enable computer products to go into low power states while not being used. This
monitor has a low power “sleep” mode, which is compliant with the EPA requirements for the
“ENERGY STAR’“” program, and will assist you in conserving energy.
Please refer to the section of “POWER SAVING SYSTEM” for details.
EasyMenu
An On Screen Display function that allows direct access to adjust all operations from the front panel.
Moire Reduction
This monitor has horizontal and vertical moire reduction function.
PLUG & PLAY
This monitor is VESA DDC1/2B compliant when used with a
computer compliant with VESA DDC (Display Data Channel).

w NEVER REMOVE THE REAR COVER !
The rear cover MUST be removed only by authorized service personnel. This colour monitor
contains high voltage components.
q THE RECEPTACLE SHOULD BE CLOSE TO THE MONITOR AND EASILY
ACCESSIBLE !
n INSTALL THE UNIT IN AN ADEQUATE ENVIRONMENT !
DO NOT expose this monitor to rain or moisture to prevent electric shock or fire hazard. This unit
is designed to be used in an office or business environment.
DO NOT subject the unit to vibrations, dust, or corrosive gases.
n KEEP IN A WELL VENTILATED PLACE !
DO NOT cover this monitor or place anything against any sides (not only the top, right and left side
but also the rear and bottom side) of unit. Ventilation holes are provided at all sides of the rear
cover to prevent the temperature from rising.
n KEEP AWAY FROM HEAT SOURCES !
AVOID placing the unit in direct sunshine or near a heating appliance.
n BE CAREFUL OF MAGNETIC FIELDS !
DO NOT place a magnet, loudspeaker system, floppy disk drive, printer, or anything which will
generate magnetism near the unit. A magnetic field may cause blurred colours or distortion of the
displayed pattern.
n BE CAREFUL OF GENERATED MAGNETISM !
After the power has been turned on or “DEGAUSS” button has been pressed, the CRT is
demagnetized for approximately IO seconds. This generates a strong magnetic field around the
front cover which may affect the data stored on magnetic tape or disks near the front cover. Place
such magnetic recording equipment and tapes/disks away from this unit.
n AMBIENT ILLUMINATION
Avoid direct rays of the sun or room lighting onto the CRT screen in order to prevent eye fatigue.
w THE ENCLOSED POWER CORD SHALL BE USED IF PROVIDED !
In Europe, a proper European standard approved power cord is to be used with this monitor. For a
rated current up to 6 A, a type not lighter than HOSW-F 3G 0.75 mm’ or H05WH2-F 3G 0.75 mm’
shall be used.
In USA/Canada, use a UL LlSTEDlCSA LABELLED or CERTIFIED power cord set meeting the
following specifications
Rating: min. 125V, 7A
Length: max. 3.lm
Type: SVT or SJT
Plug type: NEMA 5-I 5P, Parallel blade, Grounding type, 125V, IOA
Failure to do so may cause fire or electric shock hazard.
n USE ONLY THE CORRECT VOLTAGE POWER OUTLET WITH SAFETY
GROUND CONNECTION !
100 - 120 V for USA, Canada, etc.
200 -240 V for Europe, etc.
(This monitor will automatically adjust to the input voltage 100 - 120 I200 - 240V.)

W CAUTION for 200 - 240V operation only
This equipment relies on the protective devices in the building installation for short-circuit and over-
current protection. Refer to the following table for the suitable number and location of the protective
devices which should be provided in the building installation.

W BE CAREFUL OF POWER CORD CONNECTION !
Before inserting the plug of the power cord into a receptacle of the correct voltage, check that the
connection portion of the power cord is clean (with no dust). Then, insert the plug of power cord to
a receptacle firmly, otherwise it may cause electrical shock or fire.
HREMOVE THE POWER CORD FOR COMPLETE SEPARATION !
For complete separation from the power source, remove the power cord from the monitor or from the
wall outlet.
n AVOID FREQUENT POWER ON-OFF SWITCHING !
DO NOT repeat OFF and ON in a short period. It may cause blurred colours or distortion of the
displayed pattern.
W BE CAREFUL OF STATIC ELECTRICITY ON CRT SURFACE !
To prevent electrical shock by the static electricity on the CRT surface, disconnect the power cord at
least 30 SECONDS AFTER turning off the power.
W ABOUT CLEANING
This monitor has a non-glare and anti-electrostatic treatment on the surface of the screen.
Use
water or alcoholic solvent with soft cloth like gauze to clean the surface of the screen.
NEVER use abrasive, glass cleaner containing highly concentrated ammonia and strong base
chemicals since they damage the surface treatment.
Clean the cabinet and controls with a lightly moistened soft cloth.
DO NOT use aerosol sprays, solvents or abrasive cleaners.

-IMPORTANT FOR UNITED KINGDOM
WORDING FOR CLASS I EQUIPMENT INSTRUCTION BOOKS AND LABELS
The mains lead on this equipment is supplied with a moulded plug incorporating a fuse, the
value of which is indicated on the pin face of the plug. Should the fuse need to be replaced,
an ASTA or BSI approved BS 1362 fuse must be used of the same rating. If the fuse cover is
detachable never use the plug with the cover omitted. If a replacement fuse cover is required,
ensure it is of the same colour as that visible on the pin face of the plug. Fuse covers are
available from your dealer.
DO NOT cut off the mains plug from this equipment. If the plug fitted is not suitable for the
power points in your home or the cable is too short to reach a power point, then obtain an
appropriate safety approved extension lead or consult your dealer.
Should it be necessary to change the mains plugs, this must be carried out by a competent
person, preferably a qualified electrician.
If there is no alternative to cutting off the mains plug, ensure that you dispose of it immediately,
having first removed the fuse, to avoid a possible shock hazard by inadvertent connection to the
mains supply.
WARNING: THIS EQUIPMENT MUST BE EARTHED
IMPORTANT
The wires in the mains lead are coloured in accordance with the following code:
Green and Yellow = Earth, Blue = Neutral, Brown = Live.
Green & Yellow
to Earth Brown to Live
Fuse
Blue to Neutral Cord Clamp
As these colours may not correspond with the coloured markings identifying the terminals in
your plug, proceed as follows:
The wire which is coloured GREEN and YELLOW must be connected to the terminal in the plug
which is marked with the letter E or by the earth symbol @ or coloured GREEN or GREEN and
YELLOW.
The wire coloured BLUE must be connected to the terminal marked with the letter N or coloured
BLUE or BLACK. The wire coloured BROWN must be connected to the terminal marked with
the letter L or coloured BROWN or RED.
