Place The Display On A Solid Surface
Ensure that the LCD display is placed in a position to allow free flow of air. Do not cover the ventilation openings on the back cover� Do not place the display near any open flames. Do not allow the display to be placed in an environment where it can be exposed to heat, direct sunlight, or rain and water � Do not 
expose the equipment to any liquid�
Antenna Connection
Unless your LCD display is connected to a cable TV system or to a centralized antenna system, a good outdoor color TV antenna is recommended for best television performance� However, if you are located in an exceptionally good signal area that is free from interference and multiple image ghosts, an indoor antenna may be sufficient.
When using a 75-Ohm coaxial cable system, connect the CATV coaxial cable to the AIR/CABLE (75-Ohm) terminal� Or if you have an antenna, connect the coaxial cable to 
the same AIR/CABLE terminal�
