Product Description. Atomic Alarm Clock – The Atomic Clock has a built in receiver that automatically synchronizes itself with the WWVB radio broadcast by the US Government’s National Institute of Standards and Technology (NIST) in Fort Collins, Colorado. … The backlight will also illuminate when the alarm sounds.
What is demand backlight?
On Demand Blue Backlight – The clock features a built-in blue backlight to illuminate the screen when snooze/light button is pressed. You can easily illuminate the display with its blue backlight by pressing the snooze button. The display will light up for 5 seconds and turn off to extend your battery life.
Wave (Enforced Signal Receipt): This is best done at night when the signal is strongest. Hold the WAVE button down for 3+ seconds. Once the WAVE feature is activated, the hands will automatically reset to the 12:00 position, and the movement will attempt to enforce a signal receipt from Fort Collins, CO.
How long does an atomic clock last?
Most of the clocks run on AA or AAA batteries. The batteries in the watches and wall clocks usually last about 2 years. The batteries in the digital clocks usually last about a year.
Do atomic clocks still work?
The radio controlled clocks (atomic clocks) sold in North America are permanently tuned to receive and synchronize with the National Institute of Standards and Technology atomic clock radio station WWVB in Boulder, Colorado. … For comparison, FM radio and television broadcasters use frequencies thousands of times higher.
What is DST on a sharp atomic clock?
DST ON/OFF SWITCH: Before insert the battery, select the DST mode. The clock has programmed to automatically switch when the daylight saving time is in effect. IMPORTANT: If the Atomic Clock does not receive the WWVB signal immediately, wait overnight and it will be set in the morning. … on the back on the clock.
Does an atomic clock set itself?
Atomic clocks set themselves and automatically adjust for daylight saving time (DST) to provide the most accurate timekeeping standard possible.
What does wave mean on the back of a clock?
Wave clocks earn their title for the radio waves that accurately set their time. Long-range 60 kHz radio signals sent from the U.S. National Institute of Standards and Technology (NIST) radio station, WWVB, reach the radio receiver inside your clock and set the correct time to your time zone.
How can I boost my atomic clock signal?
Atomic clocks have antennas that are directional and reception may be improved by turning the antenna to increase signal strength. Place the radio controlled clock along a wall or near a window that faces towards Fort Collins. Locate atomic wall clocks at least 4-8 feet away from computer monitors.
How often does an atomic clock update?
Once your radio controlled clock has synchronized, it won’t decode the signal from WWVB again for a while. Most clocks only decode the signal once per day, but some do it more often (for example, every 6 hours).
Why does my atomic clock keep changing time?
If the atomic radio controlled clock is off by one or more hours, it probably has to do with the time zone setting. … Other atomic wall clocks may allow the selection of any time zone, even time zones that are outside the WWVB coverage area. When purchasing a clock, make sure that it can display the correct time zone.
