The JBL On Time Micro Loudspeaker Dock wakes you up to your favorite tunes. Compatible with docking iPods and iPhones, the On Time Micro also has an AM/FM radio and connects other portable audio devices via the auxiliary line-input for headphones-free listening through the system's two 1 3/4" full-range drivers. Docked iPod and iPhone models will also be charged, even when the On Time Micro is turned off, thanks to backup battery power. And, in the event of a power failure those same backup batteries keep the alarm clock running - ensuring you won't oversleep. Other features of the dock include JBL's Computer-Optimized Equalization (COE), which provides all encompassing sound, and Optimized Compression Topology (OCT) for clean and accurate audio. A bright, backlit LCD displays the time and all necessary track and navigation information.
