The Sony ICFC1 Alarm Clock Radio has several advanced features but still maintains its usability. You can wake up to your choice of alarm sound, use a sleep timer that plays music while you drift off to sleep and adjust the snooze time increments.
The ICFC1 alarm clock doubles as a radio; so you can wake up to your favorite radio station
This alarm clock's backup battery only keeps the time settings; It does not alarm when operating on battery
