~ 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 ~rovided in the building installation.
Informative examples of
Protective devices in sirwle - Dhase eauiDment or sub - assemblies
Case A: Equipment to be
connectedto POWER SYSTEMS
with earthed neutral reliably
identified, except for Case C
below.
Case B: Equipment to be
connected to any supply,
including IT POWER SYSTEMS
and supplies with reversible
plugs, ex&pt for Case C below.
Case C: Equipment to be
connected to" ~-wire power
systems with earthed neutral

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.
Al 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.
