casts.
Poor location and/or direction of the antenna
Transmitting station is too far away.

While listening to MW/LW
(For Australia and N.Z.; AM)
broadcasts
An unusual “beat” sound Is
heard. The unit is being used at the same time as the
television set. • Turn off the television set, or use this unit farther
away from it.
Interference from adjacent broadcast signals • Try reducing the treble sound by using the treble con­
trol.
A low-pitched “hum” sound
is heard whan the
broadcast is tuned. The AM loop antenna connection wires are too
close to the power cord. • Place the antenna connection wires and the power
cord farther apart.
A strange hissing noise Is
produced continuously or
Intermittently.
Caused by the "discharge phenomenon" and the
"oscillation phenomenon" of electric appliances
(such as fluorescent lights, TV, small series-type
motors, rectification equipment, etc.).
• Try placing this unit farther away from such equip­
ment.
