The Countdown Timers start automatically when you display the slide in the "Slide Show" view. The Countdown Timers are animated to count down per minute.
The Countdown Timers are fully editable. Here is a short description of how you can change some different elements in the product.
Change the range of time: You can change the range of time by deleting hands. For instance, if you want the timer to count down 57 minutes, take the slide with the 1-hour timer and delete the last three hands on the clock.
Change colors: You can change all the colors in the presentation. The way you do this is by double clicking on the element you wish to change color on. Then a pop-up box appears. In this pop-up box, choose "Fill" and then "Solid" if the object only has one color or "Gradient" if it has multiple. Choose the color you like in the color scroll bar and then click ok.
