FM Stereo
All factory equipped sound systems with an FM stereo radio will switch to stereo operation whenever an FM stereo broadcast is being received, and an indicator in the dial will light. Stereo operation means the radio is separating a stereo broadcast back into the original two channels, called "left" and "right." Stereo sound is noticeably more realistic to the ear. Although FM is normally static-free, reception can be limited by terrain, atmospheric conditions, station strength and distance from the transmitter. Buildings or other obstructions can cause momentary static, flutter or station swapping. If reception is poor, tuning to a stronger station will bring improvement.
