It is usually caused by local interference, such as cars, daylight lamps and hair
driers. Adjust the antenna to minimize the 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.
Ghosts are caused by the television signal following two paths. One is the direct
path, the other is re ected from tall buildings, hills, or other objects. Changing the
direction or position of the antenna may improve the reception.
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.
Read/write speed of your USB device could be too low. Make sure to use a USB
