In case of difficulty
FN NA ER a
If your tuner should not perform as expected, consult the table below to see if the problem can be corrected before seeking
help from your dealer or service representative.
General
Sound is not produced.
1. Antennas are not connected.
2. Amplifier is not connected.
3. No broadcast station is turned in.
Tuning signal indicators light unstably. Antenna is not connected properly. Check for disconnection or bad contact.

pressed. shock noise due to switching.
Occurs during FM reception only
Hiss that gets worse in stereo reception.
Rhythmic static or popping noises.
STEREO indicator does not light and recep-
tion is monaural although the station is
being broadcast in stereo.
Very weak antenna input signal.
Automobile ignition noise, especially evi-
dent when receiving weak signals.
Radio wave is so weak that the tuner forces
monaural reception.
Occurs during AM reception only
Symptom
Continuous noise sounding "zzz" interferes
reception specially in the evening or night.
Humming noise (tuning hum) is heard only
when a specific station is tuned in.
Noise from an electrical appliance (fluores-
cent lamp, etc.) or atmospheric noise is
entering the antenna.
. The noise may be due to the direction in
which the power plug is inserted into the
outlet.
2. It may be due to the condition of the
local area where the tuner is used.
Continuous, high-tone noise sounding
"tweet" or "shoo" interferes and increases.
=
. The noise may be generated from a TV.
2. It may be a beat noise due to cross-
interference between AM stations.
Troubles specific to synthesizer tuners
No station is tuned in when a preset station
key is pressed.
No station frequency has not been preset
under that key.
. Connect the loop antenna for AM and
outdoor or T-shaped antenna for FM.
2. Connect the amplifier using an audio
cord.
Tune in a station.
3.
Consider an outdoor antenna installation. {n
areas remote from the transmitter a 5 to 8
element antenna designed exclusively for
FM is suggested.
Review antenna installation. Site the an-
tenna as far from the street as possible and
use coaxial cable.
Install a dedicated FM outdoor antenna to
ensure sufficient radio wave reception.
The noise can be reduced by installing an
outdoor AM lead antenna and providing
grounding to the tuner.
However, it is difficult to eliminate such
noise completely.
. Insert the power plug so that the bacles
are plugged in the different power outlet
slots from before.
2. It is not avoidable that hum noise inter-
feres with specific stations as long a AC
power supply is used.
. Switch off the TV. (Also remember that
the noise could be due to another TV in
your neighbors.)
2. It cannot be eliminated because it is
based on the characteristics inhernt to
AM radio system.
Remedy
Check the frequency of desired station and
preset it securely.
