INDICATIONS
TROUBLE SHOOTING
in initially installing this receiver, improper connections may result in one of
the following indications of trouble, Their possible causes and corrective measures
are listed below to facilitate installation.
Occurs Only During AM Reception
Cause Correction
Continuous low frequency buzz. Most notice-
able at night on weak signal stations.
Continuous high frequency whine which in-
creases at night.
Intermittent buzzing or sharp crackling roise.
Interference from amateur stations
Interference from electrical appliances or at-
mospherics.
TV interference.
10 kHz beat interference from adjacent AM sta-
tion.
Lightning interference.
Interference from fluorescent lamps.
AC Plug Connection.
Called BCI, this interference results from
neighboring amateur stations.
{Also occurs on FM}
Erecting a 10 meter outdoor antenna and securing good
ground conditions should reduce interference consid-
erably. Complete elimination is difficult.
Turn TV off. (Neighboring TV set may also be cause.)
Impossible to eliminate from receiver side. This is one
disadvantage of the AM broadcast system. Use High
Filter to cut off high frequency interference.
Occurs when lamps are on and cannot be not helped.
Try reversing AC plug connections.
Occurs only on certain stations due to high voltage power
line and cannot be helped in many areas.
Consult interfering station operator or authorities con-
cerned.
Occurs Only During FM Reception Cause Correction
Continuous hiss or buzzing interference with
broadcast, Becomes louder during stereo.
Occasional sharp buzzing or crackling noise.
Weak right channel response when listening
to LEFT only test FM Stereo broadcast.
FM Automatic Circuit fails to respond to
stereo broadcast.
14
Incoming signal too weak at ANT terminal.
Automobile ignition noise. More noticeable on
weak signals.
Called crosstalk, a very slight response is
normal.
Incoming signal is exceptionally weak.
Erect outdoor FM antenna if only indoor T-type is
used. A 5 or 7 element antetina is necessary if you
are located at a considerable distance from the broad-
casting station.
Erect outdoor FM antenna as far away from roads as
practicable.
If leakage is less than one tenth, it is not a sign of trouble.
It cannot be reduced to zero.
Erect an FM outdoor antenna.
