Projection alarm clocks are digital clocks that use a small light to project the time on a nearby wall or ceiling. Many projection alarm clocks receive a radio-controlled time signal, sometimes called an atomic signal, to help them keep near perfect time. Some models even offer additional features such as temperature and humidity indicators. Setting up your projection alarm clock requires little effort and doesn't take long.

Instructions

  1. 1

    Set the time on your projection alarm clock at night when the atomic time signal is strongest. Perform the set-up near a window and at least six feet away from electronics such as televisions and computers.

  2. 2

    Insert two AA batteries into the battery compartment of your clock. Most atomic clock manufacturers recommend that you use alkaline instead of rechargeable batteries.

  3. 3

    Leave your clock undisturbed for up to 20 minutes while it searches for the atomic time signal. Your clock will display the correct local time once it has received the radio-controlled time signal from Fort Collins, Colorado.

  4. 4

    Position your clock no more than seven feet away from the wall or surface where you want the time projected. Tilt your clock's projection arm, if applicable, toward the selected wall or surface.

  5. 5

    Hold the "Snooze" button on your clock to use its projection feature. Plug your clock into an electrical socket to have the time projected continuously.

Tips and warnings

  • Consult the user manual or contact your clock's manufacturer for setting information that may be specific to your particular model.
  • Select a new location for your clock if it has trouble receiving the daily atomic time signal. Remember to position your clock away from large electronics and metal building materials that can block the radio-controlled time signal.
