Normal Operation
The antenna receives audio wave signals and transmits them to the audio unit through the coaxial antenna cable(s). When the SEEK/SCAN buttons are pressed, the audio unit searches for an audio signal of sufficient strength. When the audio unit receives such a signal, it converts the information into a fluctuating AC voltage, which it sends to the speakers.
Possible Causes
- Antenna cable
- Noise suppression equipment
