[. . . ] This device complies with part 15 of the FCC Rules. Quick Start Guide Thank you for purchasing Griffin iTrip. [. . . ] iTrip lets you listen to your iPod's audio through your home or car FM receiver. iTrip works with the 3G, 4G, and iPod Photo models, and requires the use of the iPod's dock connector. Here's how to get started using iTrip: FM Transmitter for iPod Getting Started 1. Select an FM frequency on your stereo receiver. Choose a frequency on which you hear nothing but static with no audio in the background. Since DX mode produces a stronger, cleaner signal, you may want to switch to DX mode, especially if your iPod is far away from the receiver. To switch between LX or DX mode, press and hold iTrip's station selector for 3 seconds. The current mode indicator (LX or DX in iTrip's display) will flash. Move the selector switch to the desired mode, then press the switch to confirm your selection.
