More gentle than traditional jarring alarms, this clock uses gradually increasing light, stimulating aromas, and peaceful nature sounds to awaken sleepers. At 30 minutes before wake-up, the clock's light begins to glow softly, brightening over the next half-hour. The warmth from the lamp releases faint aromatherapy scents into the air to stimulate the olfactory senses. Fifteen minutes before wake-up, the clock generates your choice of six soft nature sounds, such as ocean surf or songbirds. A beeper sounds at the end of the cycle. Can also be used with sound or beeper only. Included are four types of aromatherapy beads (Energy, Morning Café, Stress Relief, and Lavender) along with 10 felt disks for your own aromatherapy oils. With snooze, headphone jack, volume control. AC powered; requires two AA batteries for backup power. 7 1/2" H x 5 1/4" W x 6 1/4" D. (3 1/2 lbs.)
