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 that generates
magnetism, such as a converter, or high voltage power
lines.
for 100 to 120 V AC
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 ball point pen or
screwdriver. This type of contact may scratch the picture
tube.
Plug and Play
TM
This monitor complies with the DDC
1 and DDC2B Display
Data Channel (DDC) standards of VESA.
When a DDC1 host system is connected, the monitor
synchronizes with the V. CLK in accordance with the VESA
standards, and outputs the EDID (Extended Display
Identification Data) to the data line.
When a DDC2B host system is connected, the monitor
automatically switches to the appropriate standard.

Warning on Power Connection
• Use an appropriate power cord for your local power
supply.
For customers in the U.S.A.
If you do not use an appropriate power cord, the monitor
will not conform to mandatory FCC standards.
Examples of plug types:
for 220 to 240 V AC
for 240 V AC only
• Before disconnecting the power cord, wait for 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 monitor. Place magnetic recording
equipment, tapes and disks away from this monitor.
The socket should be installed near the equipment and
be easily accessible.
• Your monitor operates according to DDC2B. Only
computers that support the same guidelines and operate
at the same or higher level can make use of this feature.
• If your computer does not support the relevant
guidelines, you can still use your monitor and computer.
You may need to manually specify the appropriate
resolution in the computer.
• The highest resolution automatically selected may not
give the best result. You may need to manually select the
most suitable resolution in the computer.
