Kenwood KT-5020 - Manual (Page 11)

In case of difficulty
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
Symptom Cause Remedy
Sound is not produced. 1. Antennas are not connected.
2. Amplifier is not connected.
3. No broadcast station is turned in.
1. Connect the loop antenna for AM and
outdoor or T-shaped antenna for FM.
2. Connect the amplifier using an audio
cord.
3. Tune in a station.
Tuning signal indicators light unstably. Antenna is not connected properly. Check for disconnecjjon or bad contact.
Sound is interrupted when a switch is
pressed. Muting is applied temporarily to prevent
shock nois.e .due to switching. This is not a malfunction.
Occurs during FM reception only
Symptom Cause Remedy
Hiss that gets worse in stereo reception. Very weak antenna input signal. Consider an outdoor antenna installation. In
areas remote from the transmitter a 5 to 8
element antenna designed exclusively for
FM is suggested.
Rhythmic static or popping noises. Automobile ignition noise, especially evi­
dent when receiving weak signals. Review antenna installation. Site, the an­
tenna as far from the street as possible and
use coaxial cable.
STEREO indicator does not light and recep­
tion is monaural although the station is
being broadcast in stereo. Radio wave is so weak that the tuner forces
monaural reception. Install a dedicated FM outdoor antenna to
ensure sufficient radio wave reception.
Occurs during AM reception only
Symptom Cause Remedy
Continuous noise sounding "zzz" interferes
reception specially in the evening or night. Noise from an electrical appliance (fluores­
cent lamp, etc.) or atmospheric noise is
entering the antenna.
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.
Humming noise (tuning hum) is heard only
when a specific station is tuned in. 1. 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.
1. Insert the power plug so that the blades
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 as AC
power supply is used.
Continuous, high-tone noise sounding
"tweet" or "shoo" interferes and increases.
1. The noise may be generated from a TV.
2, It may be a beat noise due to cross-
interference between AM stations.
1. 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 inherent to
AM radio system.
Troubles specific to synthesizer tuners
Symptom Cause Remedy
No station is tuned in when a preset station
key is pressed. No station frequency has not been preset
under that key. Check the frequency of desired station and
preset it securely.
The whole of the memory stored under the
preset station keys has disappeared. Memory backup could not function because
the power was not supplied through the
power cord. The power cord must be connected to a
wall outlet or an "unswitched" power out­
let.
