This is the clock that illuminates written reminders on its integrated dry-erase board when the alarm sounds in the morning. Ideal for noting appointments, important calls, or household tasks before going to sleep, the clock’s clear plastic board provides a 5 1/2"-wide x 2 3/4"-high writing surface. When the alarm goes off or when the top of the board is tapped, the clock’s internal LED causes any message inscribed using the included blue-ink dry-erase pen to glow. Clock displays 12/24-hour time in 3/4"-high numbers, and switches to year/date, room temperature (Fahrenheit or Celsius) or a countdown timer at the touch of a button. Provides three alarm settings and plays 16 different alarm melodies. Requires three AAA batteries. 5 1/2" W x 4 3/4" H x 2 1/2" D. (12 oz.)
