LM540 2 17NOV04 For Your Safety 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. LM540 · 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. · Do not overload power strips and extension cords. Overloading can result in fire or electric shock. · 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. 3.5A. · The wall socket should be installed near the equipment and should be easily accessible. LM540 3 17NOV04 For Your Safety Special Notes on LCD Monitors The following symptoms are normal with an LCD monitor and do not indicate a problem: · 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. · 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. LM540 General Notes · Do not install the monitor near heat sources such as radiators or air ducts. · Do not place monitor in direct sunlight or in areas with excessive dust, mechanical vibration or shock. · Save the original shipping carton and packing materials in case you need to ship your monitor.

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.
