comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits
are designed to provide reasonable protection
against harmful interference in a residential
installation. This equipment generates, uses and
can radiate radio frequency energy, and if not
installed and used in accordance with the
instructions, may cause harmful interference to
radio communications. However, there is no
guarantee that interference will not occur in a

harmful interference to radio or television
reception, which can be determined by turning the
equipment off and on, the user is encouraged to
try to correct the interference by one or more of
the following measures:
1. The changes or modifications not expressly
approved by the party responsible for
compliance could void the user's authority to
operate the equipment.
2. Shielded interface cables and AC power cord, if
any, must be used in order to comply with the
emission limits.
3. The manufacturer is not responsible for any
radio or TV interference caused by
unauthorized modification to this equipment. It
is the responsibility of the user to correct such
interference.
As an ENERGY STAR® Partner, Envision
Peripherals, Inc. has determined that this product
meets the ENERGY STAR® guidelines for energy
efficiency.
1. Reorient or relocate the receiving antenna.
2. Increase the separation between the
equipment and receiver.
3. Connect the equipment into an outlet on a
circuit different from that to which the receiver is
connected.
4. Consult the dealer or an experienced radio/TV
technician for help.

Warning
To prevent fire or shock hazard, do not expose the
monitor to rain or moisture. Dangerously high
voltage is present inside the monitor. Do not open
the cabinet. Refer servicing to qualified personnel
only.

Precautions
• Do not use the monitor near water, e.g. near a
bathtub, washbowl, kitchen sink, laundry tub,
swimming pool or in a wet basement.
• Do not place the monitor on an unstable cart,
stand, or table. If the monitor falls, it can injure
a person and cause serious damage to the
appliance. Use only a cart or stand
recommended by the manufacturer or sold with
the monitor. If you mount the monitor on a wall
or shelf, use a mounting kit approved by the
manufacturer and follow the kit instructions.
• Slots and openings in the back and bottom of
the cabinet are provided for ventilation. To
ensure reliable operation of the monitor and to
protect it from overheating, be sure these
openings are not blocked or covered. Do not
place the monitor on a bed, sofa, rug, or similar
surface. Do not place the monitor near or over
a radiator or heat register. Do not place the
monitor in a bookcase or cabinet unless proper
ventilation is provided.
• The monitor should be operated only with the
type of power source indicated on the label. If
you are not sure of the type of power supplied
to your home, consult your dealer or local
power company.
• Do not overload power strips and extension
cords. Overloading can result in fire or electric
shock.
• For use only with power adaptor manufactured
by CHI SAM ELECTRONIC, model CH-1205.
LM-700
LM-700
• The monitor is equipped with a three-pronged
grounded plug, a plug with a third (grounding)
pin. As a safety feature, this plug will only fit
into a grounded power outlet. If your outlet
does not accommodate the three-wire plug,
have an electrician install the correct outlet, or
use an adapter to ground the appliance safely.
Do not defeat the safety purpose of the
grounded plug.
• Unplug the unit during a lightning storm or
when it will not be used for long periods of time.
This will protect the monitor from damage due
to power surges.
• Never push any object into the slot on the
monitor cabinet. It could short circuit parts
causing a fire or electric shock. Never spill
liquids on the monitor.
• Do not attempt to service the monitor yourself;
opening or removing covers can expose you to
dangerous voltage and other hazards. Please
refer all servicing to qualified service personnel.
• To ensure satisfactory operation, use the
monitor only with UL-listed computers which
have appropriately configured receptacles
marked between 100 - 240 V AC, Min. 5A.
• The wall socket should be installed near the
equipment and should be easily accessible.
• Disconnect the power cord to stop the power
supply to the monitor.

Special Notes on LCD Monitors
General Notes
The following symptoms are normal with an LCD
monitor and do not indicate a problem:
• Do not install the monitor near heat sources
such as radiators or air ducts.
• Due to the nature of the fluorescent light, the
screen may flicker during initial use. Turn off the
Power Switch and then turn it on again to make
sure the flicker disappears.
• Do not place monitor in direct sunlight or in
areas with excessive dust, mechanical vibration
or shock.
• You may find slightly uneven brightness on the
screen depending on the desktop pattern you
use.
• The LCD screen has effective pixels of 99.99%
or more. It may include blemishes of 0.01% or
less such as a missing pixel or a pixel lit all of
the time.
• Due to the nature of the LCD screen, an afterimage of the previous screen may remain after
switching from an image that has been
displayed for hours. This after-image could
require several hours to disappear.
• The life of the fluorescent light used in the LCD
monitor is approximately 20,000 hours. Contact
your dealer or EPI service center for
replacement when the screen is dark, flickering
or not lighting up. Never attempt to replace it by
yourself.
LM-700
• Save the original shipping carton and packing
materials in case you need to ship your monitor.
Be sure to repackage your monitor as it was
originally packed at the factory.
• Periodically clean your monitor with a soft cloth.
Stubborn stains may be removed with a cloth
lightly dampened with a mild detergent solution.
Never use strong solvents such as thinners,
benzene, or abrasive cleaners, since these
will damage the cabinet. Always unplug the
monitor before cleaning it.
Using the Right Power Cord
The supplied power cord is a NEMA 5-15 style
plug. It is UL-listed and CSA labeled for
125 volts AC.
If the monitor will be connected to your computer’s
power outlet, use a minimum No. 18 AWG, type
SJT or SVT three conductors cord with one end
terminating with a male grounded plug, rated 10A,
250V, CEE-22. The other end must terminate with
a molded-on type connector body, rated 10A,
250V, having standard CEE-22 female
configuration.

How to Optimize the DOS-mode
Plug & Play DDC1/2B Feature
1. Insert the Windows 95/98/2000/ME INF Driver
Disk into your floppy drive.
This monitor is equipped with VESA DDC1/2B
capabilities according to the VESA DDC
STANDARD. It allows the monitor to inform the
host system of its identity and, depending on the
level of DDC used, communicate additional
information about its display capabilities. The
communication channel is defined in two levels,
DDC1 and DDC2B.
2. Open Windows Explorer to search on the
floppy drive (Drive A:) to find the Dos1.exe file.
3. Double-click on the Dos1.exe file.
4. Expand the picture to full screen by pressing
the icon on the top of window. If there is no
icon, the picture is already at full screen.
If you don't have the driver disk:
1. Choose Start / Programs / MS-DOS mode.
2. Type C:\> EDIT and press Enter. You will be in
the Dos-Editor screen.
1. Change the resolution to 640 x 400
2. Press the Power button off and then on.
3. Press the AUTO button for 2 seconds.
Note: the above procedure must process
in full-screen pattern.
The DDC1 is a unidirectional data channel from
the display to the host that continuously transmits
EDID information. The DDC2B is a bidirectional
data channel based on the I²C protocol. The host
can request EDID information over the DDC2B.
3. Press the AUTO button on the front of your
monitor for 2 seconds. The screen will be
automatically adjusted.
