In this tutorial, you will be selecting the weather channel for your portable Weatheradio. The first time you use your Weatheradio, it is automatically set to use the NOAA weather broadcast frequency 162.400 MHz (Channel 1) and receive all SAME alert signals (all locations mode) broadcast within a 50-mile radius of where you installed it. Your Weatheradio is preprogrammed with seven national NOAA broadcast frequencies (Channel 1-7). Depending on your location, you might need to select a different channel.
