FM

FM stereo 

reception is 

noisy.

The particular characteristics of the FM 

stereo broadcasts being received 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.

12

Try using the manual tuning method.

21

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 the multipath 

interference.

The desired 

station cannot 

be tuned in 

with the 

automatic 

tuning method.

The signal is too weak.

Try using a high-quality directional FM antenna.

12

Try using the manual tuning method.

21

Previously 

preset stations 

can no longer 

be tuned in.

This unit has been disconnected for a long 

period.

Preset the stations again.

22

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 the best reception.

Try using the manual tuning method.

21

There are 

continuous 

crackling and 

hissing noises.

The noises may result from lightning, 

fluorescent lamps, motors, thermostats or 

other electrical equipment.

Try using 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 set.
