IMPORTANT PRODUCT SAFETY INSTRUCTIONS
Read carefully and follow all warnings and instructions in this document and those marked on the product
before you operate your display. Failure to follow warnings can result in personal injury or damage to
product. Keep this document in a convenient location for future reference.
Proper Positioning of Display
Always handle your LCD display with care. Avoid touching the LCD screen. Skin oils are difficult to
remove.
Always position your LCD display on a stable and level surface or mount it on a wall. Unstable
surfaces can cause your LCD to topple and fall, resulting in possible damage or injury.
Avoid exposing the LCD display to direct sunlight or high temperatures, which can damage or shorten its
useful life.
Do not place near heat sources such as radiators, heat registers, or other appliances that generate heat.
Avoid exposing the LCD display to rain, water, moisture or high humidity.
Do not place your LCD near basins or sinks where it may come in contact with water.
Orient your LCD display away from direct sunlight to reduce glare.
Never place heavy or sharp objects on the LCD display, video cable, or power cord.
Overloading Outlets
Do not overload electrical power sources when installing the display. Overloading wall outlets, circuits,
or extension cords can result in overheating, fire, or electric shock. Use only grounded or polarized outlets.
Power Cord Protection
Minimize wear on power supply cords. Power supply cords should be routed away from foot traffic and
contact with other objects. Do not route power cord under rugs or carpeting. The cord should never be
severely bent, pinched, or twisted. Periodically inspect power cords for wear or damage, particularly near
plug and the point where it exits from the product. Unplug cord and discontinue use if damage is
discovered.
Ventilation
Slots and openings on the cabinet are provided for ventilation purposes. To ensure reliable operation of
the product and to protect it from overheating, these openings must not be blocked or covered. Keep the
LCD Display a minimum of 4 inches/10 cm away from any wall to assure sufficient airflow and

ventilation. Increased temperatures may cause fire or device failure.
To assure proper ventilation, do not block the openings by placing the LCD Display on a bed, sofa, rug or
other similar surface. Do not place it in a built-in installation, such as a bookcase or an enclosed rack,
unless proper ventilation is provided.
Other Notices and Precautions
Caution: Never remove the rear cover. There are no user serviceable parts inside. Your LCD Display
contains high-voltage parts. You may be seriously injured if you touch them.
Do not attempt repairs yourself. Your warranty does not cover repairs or attempted repairs by anyone not
authorized by LEADWELL Optical. Refer all servicing and repairs to qualified service personnel.
If smoke, abnormal noise, or strange odor is present, immediately unplug the power cord. Contact a
qualified service technician.
If your LCD Display will not be used for extended periods of time, unplug the power cord and remove the
batteries from the remote control.
Cleaning the LCD Display
