RECEPTION PROBLEMS

 

• IGNITION NOISE:

 

 

Black spots or horizontal streaks may appear, picture may flutter or drift. Usually

 

 

caused by interference from automobile ignition systems, neon lamps, electrical drills,

English

 

and other electrical appliances.

 

 

 

• GHOSTS:

 

Ghosts are caused by the television signal following two paths. One is the direct path

 

 

and the other is reflected from tall buildings, hills or some other objects. Changing the

 

 

direction or position of the antenna may improve reception. Ghosting may also be

 

 

caused by defects in the antenna system such as unshielded leads or connecting

 

 

several sets to the same antenna without using multiple antenna couplers.

 

 

• SNOW:

 

 

If your receiver is located in the fringe area of a television station where the signal is

 

 

weak, your picture may be marred by the appearance of small dots. When the signal

 

 

is extremely weak, it may be necessary to install a special antenna to improve the

 

 

picture.

 

 

 

 

 

• RADIO FREQUENCY INTERFERENCE:

 

 

The interference produces moving ripples or diagonal streaks, and in some cases,

 

 

causes loss of contrast in the picture.

 

 

• PREVENTION OF AN OBSTACLE TO RADIO RECEIVERS

 

 

This LCD TV has been designed pursuant to the FCC class B Rules. This is to

 

 

prevent a problem to Radio receivers. If this LCD TV causes a problem to Radio

 

 

receivers, then take the

 

 

following steps:

 

 

- Keep the LCD TV away from Radio.

 

 

- Adjust Radio antennas in order for the LCD TV not to receive interference.

 

 

- The antenna cable of Radio should be kept away from the LCD TV.

 

 

- Use a coaxial cable for antenna.

 

 

You can check if this LCD TV influences Radio receivers by turning off all other

 

 

equipment other than the LCD TV.
