The I-Sonic ES features a dual alarm clock that can be set to either 12-hour AM/PM or Military 24-hour time formats. You can set two different alarm times, each with a different choice of alarm. You can wake at 6:30AM to an XM radio station while your spouse wakes at 7:30AM to the alarm tone. To make your wake-up less stressful, we've made the music and alarm tone volumes come up gently and slowly from a whisper to the volume level you set the night before. We call it SoftWake. Duh.
