Quck answer
An atomic wall clock is a precise timekeeping device that uses atomic vibrations to maintain accuracy. To set an atomic wall clock, follow these steps:
1. Insert fresh batteries into the clock if needed.
2. Set the time zone by pressing the appropriate buttons on the clock.
3. Allow the clock to synchronize with the atomic time signal. This may take a few minutes.
4. Once synchronized, the clock will automatically adjust to the correct time.
5. Adjust the clock manually if necessary, using the provided buttons or knobs.
6. Hang the clock on the wall or place it in a suitable location.
By following these steps, you can easily set an atomic wall clock and enjoy its precise timekeeping abilities.
For ultimate accuracy, an atomic wall clock is the way to go. These clocks, also known as radio-controlled clocks, receive the signal from the National Institute of Standards and Technology’s atomic clock in Fort Collins, Colorado via a radio transmitter. Popular atomic clock brands include Bulova, Howard Miller, La Crosse, and Seiko.

How Atomic Wall Clocks Operate
An atomic clock includes a small antenna and a radio receiver that picks up the long wave (60 kHz) signal of WWVB, NIST’s radio transmitter. WWVB broadcasts continuously and covers most of the continental United States, with some atomic clocks in Alaska and Hawaii also receiving the signal.
When an atomic clock receives the WWVB signal, its hands move 20 times faster than usual, adjusting with an accuracy of only one second in up to 100 million years. (In other words, you can’t find a more accurate clock.) Normally, an atomic clock gets this signal at night and makes automatic adjustments to display the correct time.
Choosing Your Time Zone
Programming an atomic wall clock is straightforward. Insert the appropriate number of fresh AA LR6 alkaline batteries into the battery compartment according to the polarity markings. It’s best to do this in the evening since longwave radio signals are usually not transmitted during the day. However, if you program your clock during the day, it will still function as a precise quartz clock until it receives the WWVB signal. Select your time zone by pressing the appropriate time zone button (PT for Pacific Time, MT for Mountain Time, CT for Central Time, and ET for Eastern Time). If you press the wrong time zone button, press the correct one after that. If no time zone is chosen, the clock defaults to PT.
Daylight Saving Time
Atomic clocks take daylight-saving time into account, so if your location does not observe DST, such as the state of Arizona, you must disable the DST feature. After programming your clock, press the “DST” button (usually located just above and between the ET and CT Time Zone buttons on the back of the clock) for one second. Your clock will no longer recognize DST.
Manual Programming
If your time zone is not PT, MT, CT, or ET, you must program the time manually. Find and press the Manual Time Set button on the back of your clock until you reach the correct time. Place your clock upright near a window to help it locate its initial signal. Within a few minutes, your clock will locate the WWVB signal and set itself to the correct time or determine that it cannot receive the signal at this location and time of day. It will periodically look for the WWVB signal and automatically adjust the hands when it receives it. Some atomic clocks may have a WWVB search button that searches for the WWVB signal when pressed.
Where to Place an Atomic Wall Clock
For best results, position your atomic wall clock near a window facing Colorado. It’s important to keep it at least six feet away from household electrical appliances, such as TVs, computers, and air conditioners. While the WWVB signal can penetrate most residential and steel buildings with windows, it may not reach inside windowless rooms in large office buildings or shopping malls. In such locations, it’s recommended to set the time manually, as the clock will still detect the WWVB signal and adjust the time accordingly when it receives it.
FAQ
1. How do I set the time on an atomic wall clock?
To set the time on an atomic wall clock, start by inserting fresh batteries into the clock if necessary. Next, locate the time zone setting on the back of the clock and adjust it to your specific time zone. Once the time zone is set, the clock will automatically receive the atomic signal and set the correct time. If the clock does not receive the signal immediately, it may take up to 24 hours to synchronize. It’s important to place the clock in a location where it can receive the atomic signal, such as near a window or away from electronic devices.
2. How often does an atomic wall clock update its time?
An atomic wall clock updates its time automatically on a regular basis. Most atomic clocks receive a radio signal from an atomic clock located at the National Institute of Standards and Technology (NIST) in the United States. This signal is transmitted several times a day and contains the precise time information. Atomic wall clocks typically update their time once a day or every few hours, depending on the model. However, it’s important to note that the frequency of updates may vary depending on the location and the strength of the radio signal.
3. Can I manually set the time on an atomic wall clock?
While atomic wall clocks are designed to automatically set the correct time, some models may also allow manual time setting. However, it’s generally recommended to rely on the automatic time synchronization feature to ensure accurate timekeeping. Manually setting the time on an atomic wall clock can be tricky and may result in inaccurate time display. If you find that your atomic wall clock is consistently displaying the wrong time, it’s best to consult the manufacturer’s instructions or contact customer support for assistance.
