The Large Time Timer is designed to be wall hung for classroom and group activities. It’s large size (12 inches square) and bold dial numerals make this timer easier to read for visually impaired users, as well.
How it works:
To set the Large Time Timer, move the red disc counterclockwise to the desired time interval. The disc diminishes as time elapses until no red is visible on the timer face. The disc may be moved clockwise or counterclockwise without harming the mechanism, however gentle handling will prolong the life of the timer.
