The Sangean Model DT-400W is the last pocket radio you will ever need to buy. It has about everything you could want, and then some, in a small, pocket sized portable radio. As an example the new NOAA Weather Alert Emergency Channel sounds a very loud audible tone when an extreme weather condition is imminent and/or a police emergency or a child abduction has occurred or any type of public awareness becomes critical. Even with your radio off or you are listening to another station the weather alert monitor continues to monitor the NOAA channels should an emergency arise. To conserve battery life the DT-400W provides an option to select the time you would like the NOAA alert to be active and a small LED alert flashes to remind you that the alert is on. In addition to emergencies the 7 NOAA channels provide up to date general weather information useful if you're planning a trip or just a picnic for the weekend. The large backlit LCD display clearly displays the time, station, battery life indication, alert indication and all other pertinent information. Advanced PLL Synthesized Digital Receiver provides drift free AM/FM reception. Deep Bass Boost adds to your stereo musical listening pleasure and 19 random preset selections lets you mix AM/FM stations with immediate access through the "My Favorites" button. Other features include Lock Switch to prevent accidental set-up changes, optional 90 minute auto shutoff, built-in speaker, auto station seek and a removable belt clip.
