• The radio waves used by the product are high frequency, so that
there are features such as direct advance travelling, reflection,
refraction, diffraction, interference etc., similar to that of light. The
strength of the waves therefore varies depending on the location,
which may cause the pictures and sound to become unclear,
become wavy, or stop.
• Is the distance between the Wireless Center and the television
product too far? Use within a range that the radio waves can reach.
• Are you at a location that is particularly susceptible to electrical
noise?
• Set “DISTANCE” to “FAR”.
• The product utilizes wireless transmissions, so that fast moving
images may become distorted, but this is not a malfunction.
