Precautions
Installation
• Prevent internal heat build-up by allowing adequate air
circulation. Do not place the monitor on surfaces (rugs,
blankets, etc.) or near materials (curtains, draperies) that
may block the ventilation holes.
• Do not install the monitor near heat sources such as
radiators or air ducts, or in a place subject to direct
sunlight, excessive dust, mechanical vibration, or shock.
• Do not place the monitor near equipment which generates
magnetism, such as a transformer or high voltage power
lines.
Maintenance
• Clean the cabinet, panel and controls with a soft cloth
lightly moistened with a mild detergent solution. Do not
use any type of abrasive pad, scouring powder, or
solvent, such as alcohol or benzine.
• Do not rub, touch, or tap the surface of the screen with
sharp or abrasive items such as a ballpoint pen or
screwdriver. This type of contact may result in a scratched
picture tube.
• Clean the screen with a soft cloth. If you use a glass
cleaning liquid, do not use any type of cleaner containing
an anti-static solution or similar additive as this may
scratch the screen's coating.
Transportation
When you transport this monitor for repair or shipment, use
the original carton and packing materials.

This monitor can be adjusted within the angles shown
below. To find the center of the monitor's turning radius,
align the center of the monitor's screen with the centering

Note
Do not remove the tilt-swivel base from the monitor.
Warning on power connection
• Use an appropriate power cord for your local power
supply.
Examples of plug types:
for 100 to 120 V AC
for 200 to 240 V AC
for 240 V AC only
• Before disconnecting the power cord, wait at least 30
seconds after turning off the power to allow the static
electricity on the CRT display surface to discharge.
• After the power has been turned on, the CRT is
demagnetized (degaussed) for about 5 seconds. This
generates a strong magnetic field around the metal frame,
which may affect the data stored on magnetic tapes and
disks near the bezel. Place magnetic recording equipment,
tapes, and disks away from this monitor.
The equipment should be installed near an easily
accessible electrical outlet.
The operating instructions mentioned here are partial abstracts
from the Operating Instruction Manual. The page numbers of
the Operating Instruction Manual remein as in the manual.
