FM
FM stereo reception is 
noisy.
The characteristics of FM stereo 
broadcasts may cause this problem 
when the transmitter is too far away or 
the antenna input is poor.
Check the antenna connections.
Try using a high-quality directional FM 
antenna.
19
Use the manual tuning method.
35
There is distortion, and 
clear reception cannot 
be obtained even with a 
good FM antenna.
There is multipath interference.
Adjust the antenna position to eliminate 
multipath interference.
The desired station 
cannot be tuned in with 
the automatic tuning 
method.
The signal is too weak.
Use a high-quality directional FM antenna.
19
Use the manual tuning method.
35
Previously preset 
stations can no longer 
be tuned in.
This unit has been disconnected for a 
long period.
Preset the stations again.
35
AM
The desired station 
cannot be tuned in with 
the automatic tuning 
method.
The signal is weak or the antenna 
connections are loose.
Tighten the AM loop antenna connections 
and orient it for best reception.
Use the manual tuning method.
35
There are continuous 
crackling and hissing 
noises.
Noises result from lightning, 
fluorescent lamps, motors, thermostats 
and other electrical equipment.
Use an outdoor antenna and a ground wire. 
This will help somewhat, but it is difficult to 
eliminate all noise.
There are buzzing and 
whining noises.
A TV set is being used nearby.
Move this unit away from the TV.
