Check the speaker connections and ensure they are secure. Also, make sure the volume is not set too high, and the audio source is not distorted.
Use a soft, dry cloth to clean the exterior. For the CD lens, use a lens cleaning disc designed for CD players. Avoid using liquid cleaners.
Ensure the power cord is securely plugged into a working outlet. Check the fuse or circuit breaker and replace or reset as necessary.
To reset the system, unplug the power cord for a few minutes, then plug it back in. This will restore factory settings.

Dust the speakers regularly with a soft cloth. Ensure they are kept dry and avoid exposing them to direct sunlight or heat.
Extend and adjust the FM antenna for better reception. For AM stations, reposition the unit to minimize interference.
