Discontinue Usage 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!

The colour monitor contains high voltage components. Ask your dealer to repair or clean inside.

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. so as 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 or place anything against any sides (not only the top, right and left side but also the rear and bottom sides) of the monitor. Ventilation holes are provided at all sides of covers to prevent excessive temperature increase.

Be cautious 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.

Be mindful of the ambient illumination!

Avoid direct rays of the sun or room lighting onto the CRT screen in order to prevent eye fatigue.

The 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 safety ground connection!

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

Be cautious 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.

1 Remove the power cord for complete separation!

For complete separation from the power source, remove the power cord from the monitor or from the wall power outlet.

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.

Informative examples of protective devices in single - phase equipment or sub - assemblies

	Protection against	Minimum number of fuses or circuit - breaker poles	Location
Case A: Equipment to be connected to POWER SYSTEMS with earthed neutral reliably identified, except for Case C below.	Earth faults	1	Phase conductor
	Overcurrent	1	Either of the two conductors
Case B: Equipment to be connected to any supply, including IT POWER SYSTEMS and supplies with reversible plugs, except for Case C below.	Earth faults	2	Both conductors
	Overcurrent	1	Either of the two conductors
Case C: Equipment to be connected to 3-wire power systems with earthed neutral reliably identified.	Earth faults	2	Each phase conductor
	Overcurrent	2	Each phase conductor

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

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.

Avoid frequent power ON-OFF switching!

Do not repeat OFF and ON power switching in a short period. This may cause blurred colours or distortion of the displayed pattern.

Be careful of generated magnetism!

After the power has been turned ON or when the degauss function has been manually engaged, the CRT is demagnetised for approximately 7 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.

About cleaning

Before cleaning, turn OFF the power switch 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 synthetic detergent, with a lightly moistened soft cloth. Do not clean the inside of monitor by yourself as it is very dangerous. Refer to your dealer. Do not use aerosol sprays, solvents or abrasive cleaners.
