By that, it means it can scan the entire radio spectrum (88.1 – 107.9 MHz) to find the optimal FM signal to transmit to in less than six seconds. The device has three presets, enabling you to store stations that are regularly available so they can be found instantly. It can also charge your iPod from the cigarette lighter while it plays the music through the car radio. Or the charger can then be detached, making the transmitter portable, transmitting to any FM radio within range.
