PICTURE CAUTIONS

When using TV games, computers and similar products with your TV or watching a TV show such as TV broadcast with stationary images like a home shopping program, stock market exchange, etc., keep the CONTRAST and BRIGHTNESS functions at low settings. If a fixed (non-moving) pattern is left on the screen for long periods of time at a high CONTRAST or BRIGHTNESS setting, the image can be permanently imprinted onto the screen. These types of imprints are not covered by your warranty because they are the result of misuse.

This color television receiver was intended mainly for the private viewing of programs broadcast by TV stations and cable companies and programs from other video sources. Public viewing may require prior authorization from the broadcaster or owner of the video program.
