CONNECTING THE POWER CORD
· Check first to make sure that the power cord you use is the correct type required for
your area.
· This monitor has a universal power supply that allows operation in either 100/120V
AC or 220/240 V AC voltage area. No user-adjustment is required.
· Plug one end of the power cord to the AC Inlet, plug another end to a proper AC outlet.
· For unit using at 120 V AC:
Use a UL Listed Cord Set, Type SVT wire and plug rated 10 A/125 V.
· For unit using at 220/240 V AC (outside of U.S.):
Use a Cord Set consisting of H05VV-F cord and plug rated 10 A, 250 V. The cord set
should have the appropriate safety approvals for the country in which the equipment
will be installed.
SAFETY PRECAUTION
· Avoid placing the monitor, or any other heavy object, on the power cord to prevent
it from fire or electrical shock.
· Do not expose the monitor to rain, excessive moisture, or dust to avoid fire or shock
hazard.
· Do not cover the slots or openings of the monitor for proper heat dissipation.

PRESET MODES
To reduce the need for adjustment for different modes, the monitor has default setting
modes that are most commonly used as given in the table below. For optimum adjustment,
the user is suggested to perform the Auto Setup under Windows “Full Screen” pattern or
using the pattern in the floppy disk provided. When none of the mode is matched, the user
can store their preferred modes in the user modes. The monitor is capable of storing up to
9 user modes. The only condition to store as a user mode is the new display information
must have 1 KHz difference for horizontal frequency or 1 Hz for vertical frequency or the
sync signal polarities are different from the default modes.
