If irregular coloring occurs on your television
The front and center speakers are designed to be used close to a television, but the picture may be affected with some
televisions and setup combinations.
If this occurs, turn the television off for about 30 minutes.
The demagnetizing function of the television should correct the problem.
If it persists, move the speakers further away from the television.
