Getting Started
Warning on power connection
• Use an appropriate power cord for your local power
supply.
Examples of plug types
• 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 3 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 outlet should be installed near the equipment
and be easily accessible.
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.
