In most instances you can manually control electronics in your home and office. When you are going to be out, you can just switch off a desk lamp on your way out the door. There are plenty of times when it can help to have an automatic system in place to control the power to various appliances. Holiday lights, for example, are often left on too long because the homeowner forgets to cut the power when they go to bed. Using an Ingraham digital timer provides more control and saves time and money.

Use the arrow buttons to select the correct hour. Press the "Set" button until the "Minutes" icon flashes. Use the arrow buttons to select the current minute.

Program the timer. The Ingraham digital timer can hold up to 20 different programs. Press the right arrow button until the program number that you want appears next to the word "On." Press the "Set" button until the "Days" option flashes and use the arrows to select the days that you would like to timer to operate on for this particular program.

Use the arrows to select the minutes needed. Press "Set" again until the program number you just worked with flashes, indicating that this timer program is on. Use the arrow button to either turn this timer program off or navigate to the next program number, repeating this process to program as many of the 20 available program slots as you like.

The random timer setting is ideal for when you are away from home and want the house to appear occupied. Lights and other electronics plugged into the timer will randomly cycle on and off.
