Hyundai H-LCD1502 [14/30] The causes of interference

The causes of interference

Incorporated in your TV receiver are the most up-to-date devices to eliminate interference. Local

radiation however, can create disturbances, which visibly affect your picture. Proper installations, a

good aerial are your best safeguards against these disturbances.

 RF INTERFERENCE

Moving ripples across the screen are caused by nearby transmitting or receiving short-wave

radio equipment.

 DIATHERMY

Herringbone pattern and partial picture loss can result from the operation of diathermy

equipment from a nearby doctor's surgery or hospital.

 SNOW

Weak TV signals from long distant stations result in an instead picture and give the effect of

falling snow. An antenna adjustment or antenna amplifier may be needed.

 GHOST

Multiple image caused by TV signals reflected back from surrounding buildings, hills, aircraft,

etc. is minimized by correct aerial positioning.

 CAR IGNITION

Nearby cars and electrical motors can cause small streaks across the picture or make the picture

roll.
