Radio Reception
Frequency interference and static can occur during
normal radio reception if items such as cell phone
chargers, vehicle convenience accessories, and
external electronic devices are plugged into the
accessory power outlet. If there is interference or static,
unplug the item from the accessory power outlet.
AM
The range for most AM stations is greater than for FM,
especially at night. The longer range can cause station
frequencies to interfere with each other. For better radio
reception, most AM radio stations boost the power
levels during the day, and then reduce these levels
during the night. Static can also occur when things like
storms and power lines interfere with radio reception.
When this happens, try reducing the treble on the radio.
FM Stereo
FM signals only reach about 10 to 40 miles
(16 to 65 km). Although the radio has a built-in electronic
circuit that automatically works to reduce interference,
some static can occur, especially around tall buildings
or hills, causing the sound to fade in and out.
