Unorderly ripples on the
picture
It is usually caused by local interference, such as cars, daylight lamps
and hair driers. Adjust the antenna to minimize the interference.
Snowy dots, blocking and
interference
If the antenna is located in the fringe area of a television signal where
the signal is weak, the picture may be marred by dots, show blocking
or break-ups. When the signal is extremely weak, it may be necessary
to install a special antenna to improve the reception.
1. Adjust the position and orientation of the indoor/outdoor
antenna.
2. Check the connection of the antenna.
3. Fine tune the channel.
4. Try another channel. Broadcasting failure may happen.
Ghost
Ghosts are caused by the television signal following two paths. One
is the direct path, the other is refl ected from tall buildings, hills, or
other objects. Changing the direction or position of the antenna may
improve the reception.
Radio frequency interference This interference produces moving ripples or diagonal streaks, and
in some case, loss of contrast in the picture. Find out and remove the
radio interference source.

picture freeze/macro
blocks or similar distortion,
