BATTERY INSTALLATION (REMOTE CONTROL UNIT)
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 installation, a
good aerial are your best safe-guards 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.
