automatically.
The signal is weak or the antenna
connections are loose.
Tighten the AM antenna connections and orient it for
the best reception.

Try tuning manually.

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 earth ground.
This will help somewhat, but it is difficult to
eliminate all noise.

whining noises.
A TV set is being used nearby.
Move this unit away from the TV set.

“No presets” is
displayed.
