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, 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 monitor has been designed pursuant to the FCC class B Rules. This is to prevent a

 

 

 

 

 

 

 

 

 

problem to Radio receivers. If this monitor causes a problem to Radio receivers, then take the

 

 

 

 

 

 

 

 

 

following steps:

 

 

 

 

 

 

 

 

 

- Keep the monitor away from Radio.

 

 

 

 

 

 

 

 

 

- Adjust Radio antennas in order for the monitor not to receive

 

 

 

 

 

 

 

 

 

interference.

 

 

 

 

 

 

 

 

 

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

 

 

 

 

 

 

 

 

 

- Use a coaxial cable for antenna.

 

 

 

 

 

 

 

 

 

You can check if this monitor influences Radio receivers by turning off all other equipment other
