The Sangean PR-D7 is a true portable AM/FM digital radio! All controls are conveniently located on this ultra-compact radio, and you can see the frequency and time on the easy-to-read display. With excellent sensitivity and selectivity, this radio will surprise you with its ability to pull in distant stations. Five presets are available on each band, and the auto seek will automatically seek the active stations across the entire band rather than to the next frequency. The radio can be set to automatically turn off after 120, 90, 60, 45, 30, or 15 minutes, so you can fall asleep to the sound of music, talk, or news. Sleep alarm allows you to wake up to music or beeper with Humane Wake Up System. You can power it with the included AC Adapter, or six AA size batteries (not included). In addition, the PRD-7 can be powered with six rechargeable AA batteries which you can charge right in the radio.
