Collins, Colorado, and transmits the exact time signal continuously throughout the United States at 60 kHz. [. . . ] Collins, Colorado, and transmits the exact time signal continuously throughout the United States at 60 kHz. The signal can be received up to 2, 000 miles away through the internal antenna in the projection alarm. Due to the nature of the Earth's Ionosphere, reception is very limited during daylight hours. The projection alarm will search for a signal every night when reception is best. The WWVB radio station receives the time data from the NIST Atomic clock in Boulder, Colorado. A team of atomic physicists is continually measuring every second, of every day, to an accuracy of ten billionths of a second per day. These physicists have created an international standard, measuring a second as 9, 192, 631, 770 vibrations of a Cesium-133 atom in a vacuum.

This number will connect you to an automated time, announced at the top of the minute in "Coordinated Universal Time", which is also known as Greenwich Mean Time (GMT). This time does not follow Daylight Saving Time changes. This temperature is displayed in °F or °C, depending on the time format (12 or 24 hour mode). When in 12-hour format, the temperature will be in °F. When in 24-hour mode, the temperature will be in °C. The indoor temperature will take time to adjust to the surrounding temperature as the sensor is inside the case. If the remote temperature is placed next to the projection alarm, more often than not the temperature will not be exact with one another. 4. defect, but simply reflects the difference in measuring methods. The remote temperature is designed for changing temperature at a wide range. The projection alarm comes with a remote temperature sensor. When set up properly, the projection alarm will receive and display the remote temperature. It is important to power up the sensor first, then the projection alarm. If batteries are removed in the remote, the projection alarm MUST be re-set by removing power sources and re-starting.
