The Digi-Sense WD-94440-10 Jumbo digit clock/timer features a dual 3-3/4' x 5-1/2' x 1-9/32' LCD display that tilts for easy viewing. Two channels can be operated and displayed simultaneously - use both channels to count down, or use one channel to count up and the other to count down. Built-in clock displays time of day in 12- or 24-hour formats. Timer recalls previous time set. A 70 dB alarm sounds at the end of the countdown; shuts off at the touch of a button. Timer displays time elapsed since the end of a countdown. Place timer on tabletop, or mount on wall using the double-sided taped bracket or screws (both are included).
