FEATURES

This Colour monitor provides the following features.

Sharpest Focus and Highest Contrast

ENGLISH

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 to a wide range of scanning
frequencies and user requirements.

Digital Picture Control Function

Position, size, pincushion, trapezoid, parallelogram, etc. are adjustable through digital
controls. Geometry settings can be stored for different H/V frequencies.
Microprocessor-based preset functions can store 37 sets of geometry settings, including
the default factory settings.

Digital Colour Control Function

Red, green, and blue colour balance are adjustable through digital control. An adjusted
colour setting can be stored and recalled through the colour select function.

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
Please refer to the section of “POWER SAVING SYSTEM” for details.

NERGY STAR

E

EasyMenu

An On Screen Display function that allows easy access to adjust all operations from the
front panel.

Plug & Play

This monitor is VESA DDC1/2B compliant when used with a computer compliant with
VESA DDC (Display Data Channel).

Automatic colour purity correction

The monitor uses an advanced technology to detect magnetic fields (geomagnetism) and
automatically adjusts the image to reduce colour purity distortions common with many
monitors.

NOTE:

If as an advanced user, you decide to use an external degaussing coil (other than the
degaussing function included in the digital controls of the monitor) it is strongly suggested
that the monitor be turned off. If you leave the monitor on while using the external
degaussing coil it may cause the monitor to produce uneven colour.

CAUTIONS

Discontinue Use if Abnormal Operation Occurs !

Abnormal operations such as smoke, burning smell, excessive sound, etc. could cause
fire or electrical shock. If you observe any abnormal operation, you should turn off the
monitor and disconnect the power plug from the power outlet. You should check for
smoke or fire and contact your dealer.

Do not expose the monitor to physical impact !
Do not allow foreign objects (water, metal, etc.) inside !

Never remove the cover of the monitor!

This colour monitor contains high voltage components. Ask your dealer to repair or clean
the inside if necessary

The power outlet should be close to the monitor and easily accessible !

Install the unit in an suitable environment !

Do not expose the monitor to rain, moisture, dust, corrosive gases, vibrations, etc. to
prevent electrical shock or fire hazard.
Avoid placing the monitor in direct sunlight or near heating appliances.
Do not place the monitor on an unstable base.

Keep in a well ventilated area !

Do not cover this monitor, nor place anything against any of its sides (not only the top, but
also including the right and left side of the monitor). The ventilation holes in the cover
prevent excessive temperatures inside the monitor.

Beware of magnetic fields !

DO NOT place a magnet, loudspeaker system, floppy disk drive, printer, or any appliance
which generates a magnetic field near the unit. A magnetic field may cause blurred
colours or distortion of the displayed pattern.

Mind the ambient illumination !

Avoid direct sunlight or artificial light shining directly onto the CRT screen in order to
prevent eye fatigue.

Enclosed power cord must be used !

Failure to do so may cause fire or electrical shock hazard.

Use only the correct voltage power outlet with grounded connection !

This monitor will automatically adjust to the input voltage 100 - 120 / 200 - 240V.

Beware of the power cord connection !

Before inserting the plug of the power cord into a power outlet 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 into a power outlet firmly to avoid electrical shock or fire hazard.

Remove the power cord for complete disconnection !

For complete disconnection from the power source, remove the power cord from either the
monitor or wall socket.

CAUTIONS (Continued)

CAUTION (for 200 - 240V operation only)

This equipment relies on the protective devices in the building installation for short-circuit
and power surge protection. Refer to the following table for the suitable number and

ENGLISH

location of the protective devices which should be present in the building’s installation.

Informative examples of protective devices in single - phase equipment or

sub-assemblies

Case A: Equipment connected
to POWER SYSTEMS with
reliable identified grounded
neutral, except for Case C
below.

Case B: Equipment that is
connected to any power
supply, including IT POWER
SYSTEMS and supplies with
reversible plugs, except for
Case C below.

Case C: Equipment that is
connected to 3-wire power
systems with reliable identified
grounded neutral.

Verify that the protective devices in the building installation meet the conditions in the
table prior to installing the equipment.

Be careful of static electricity on the CRT surface !

To prevent electrical shock through static electricity on the CRT surface, disconnect the
power cord for at least 30 seconds after turning OFF the power before touching the
monitor’s surface.

Avoid frequent turning ON and OFF switching !

Do not repeatedly turn the monitor OFF and ON during a short period of time. This may
cause blurred colours or distortion of the displayed patterns.

Beware of generated magnetism !

After the power has been turned ON, or when the degauss function has been manually
engaged, the CRT will be demagnetized for approximately 7 seconds. This generates a
strong magnetic field around the front cover which may affect data stored on magnetic
tape or disks near this front cover. Move such magnetic recording equipment as well as
tapes and disks away from this unit.

Cleaning the Monitor

Before cleaning, turn the monitor OFF and disconnect the plug from the power outlet.
For the screen, use water with a lightly moistened soft cloth such as a gauze type material.
For the cover, use water or a liquid (non-solvent) synthetic detergent, with a lightly moistened
soft cloth. Do not clean the inside of monitor by yourself. Refer this to your dealer.
Do not use aerosol sprays, solvents or abrasive cleaners.

For the Customers in the UK

THIS PRODUCT IS SUPPLIED WITH A 2-PIN MAINS PLUG FOR USE ON MAINLAND

ENGLISH

EUROPE. FOR THE UK PLEASE REFER TO THE NOTES ON THIS PAGE.

IMPORTANT FOR UNITED KINGDOM

WORDING FOR CLASS

The mains lead on this equipment is supplied with a molded 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 of the same rating must be used. 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 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 outlets in your home or the cable is too short to reach a power outlet, obtain an
appropriate safety approved extension lead, or consult your dealer.

Changing the mains plug, if necessary, should be carried out by an 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 GROUNDED

IMPORTANT

The wires in the mains lead are coloured in accordance with the following code:

Green & Yellow to Ground Brown to Live

Green and Yellow = Ground, Blue = Neutral, Brown = Live.
