Hyundai H-LCD4201 [19/39] 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.
