received.

camera, camcorder, or other peripheral being
connected at the same time. Switch o one of the
other peripherals.
• The ‘ghost’ or double image may be caused by
obstruction to the antenna due to high-rise buildings
or hills. Using a highly directional antenna may
improve the picture quality.

may be caused by electrical interference, e.g., hair
dryer, nearby neon lights, etc. Turn o or remove
these.
