 - The 12" Time Timer can be freestanding or wall mounted. Its large size and bold colors make it easier to read from a distance. To set the timer, move the red disc counterclockwise to the desired amount of time in minutes. The red disc disappears as time passes until no red is visible on the timer face. An optional beep for when time runs out is operated by an on/off switch on the back of the timer. The red disc may be moved in either direction to increase or decrease the time without harming it. Supports transitions and keeping everyone on the same schedule. Requires one AA battery; not included.
