INDICATIONS

TROUBLE SHOOTING

In initially installing this receiver, improper connections may result in one of
the following indications of trouble. Thei? possible causes and corrective measures
are listed below to facilitate installation.

Occurs Only During AM Reception

Continuous low frequency buzz. Most notice-
able at night on weak signal stations.

Cause

Interference from electrical appliances or at-
mospherics.

Correction

Erecting a 10 meter outdoor antenna and securing
good ground conditions should reduce interference
considerably. Complete elimination is difficult.

Continuous high frequency whine which in-
creases at night.

TV interference.
10 kHz beat interference from adjacent AM
station.

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.

Intermittent buzzing or sharp crackling noise.

Lightning interference.
Interference from fluorescent lamps.

AC Plug Connection.
Usually unavoidable in certain areas.

Occurs when lamps are switching on and cannot be
helped.

Try reversing AC plug connections.

Occurs only on certain stations due to high voltage
line or AC supply and cannot be helped.

Interference from amateur stations.

Called BCI, this interference results from
neighboring amateur stations. (Also occurs
on FM)

Consult interfering station operator or authorities
concerned.

Occurs Only During FM Reception

Cause

Correction

Continuous his or buzzing interference with
broadcast. Becomes louder during stereo.

Incoming signal too weak at ANT terminal.

Erect outdoor FM antenna if only indoor T-type is
used. A 5 or 7 element antenna is necessary if you
are located at a considerable distance from the
broadcasting station.

Occasional sharp buzzing or crackling noise.

Automobile ignition noise. More noticeable
on weak signals.

Erect outdoor FM antenna as far away from roads
as practicable.

Weak right channel response when listening
to LEFT SIDE test FM Stereo broadcast.

Called crosstalk, a very slight response is
normal.

If leakage is less than one tenth, it is not a sign of
trouble. It cannot be reduced to zero.

FM Automatic Circuit fails to respond to stereo
broadcast.

Incoming signal is exceptionally weak.

Erect a special FM outdoor antenna.
