TrueDawn™ Technology Sleep Latency Alertness TrueDawn technology wakens you exactly as nature intended by gradually increasing light just like a summer sunrise. This signals your body to complete its sleep cycle so you awaken when you need to, feeling refreshed and ready to start the day. TrueDawn synchronizes your sleep/wake cycle-helping you wake and sleep better. Just like sunrise, TrueDawn follows a sigmoidal light curve-the right type of increasing intensity- which signals the body clock without causing premature awakening. Other "dawn simulators" employ an inexpensive linear ramp-up, which can cause premature awakening and is ineffective at regulating the body clock. When you use your Daybreak, you'll awaken much easier than ever before with more energy to start the day. 5:30AM 6:00AM 6:30AM 7:00AM 7:30AM Standard alarm clock: Alarm clocks disrupt the last stages of sleep, increasing sleep latency and delaying alertness. Natural Sunrise: Natural Sunrise increases very slowly at first, allowing a gradual awakening. TrueDawn™ Sunrise Clock: The Daybreak's TrueDawnTM technology matches sunrise, allowing your sleep cycle to finish. You awaken gradually without sleep latency. 6 Display Layout MAIN CLOCK DISPLAY WAKE 1 CLOCK TIME WAKE 1 SETTING ICONS TOUCH SCREEN BUTTON PANEL WAKE 2 CLOCK TIME WAKE 2 SETTING ICONS 7 Display Layout
