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.
