How does the RediRad™ work?
The RediRad™ operates like an A/B switch: In default mode, the radio receives over-the-air signals that pass straight through the RediRad™. In RediRad™ mode, music signals (from your portable music player) enter the RediRad™ via the audio cable (that is plugged into the headphone jack) and are converted into an AM signal that the radio treats like broadcast. Turn on the radio, tune it to 10 on the AM dial (technically speaking, this is 1000 kHz) and ENJOY! The RediRad™ returns to normal broadcast-receive mode within one minute of turning off the portable music player.
