SkyScan makes over 40 models of atomic clocks that receive the time from a radio signal sent by the National Institute of Standards and Technology (NIST). The time is incredibly precise and estimated to only deviate by less than 1 second within 3,000 years. Luckily, starting your SkyScan clock is easy, whether you have a digital, analog (standard clock face), or Weather Station clock. Keep reading for simple instructions to pick up the radio signal and set the clock manually, if you need!

Setting Up a SkyScan Clock

  • On a digital clock, add 2 AA batteries and press the “Set” button on the back of the clock to select your time zone.
  • Then, hit the “Set” and “+” buttons to change the hour, minute, and date. Place the clock near a window so it finds the signal.
  • On an analog clock, add 1 AA battery and press and hold your time zone button on the back. Hang it up near a window and wait for it to sync with the signal.

  1. If your digital clock comes with a weather transmitter, slide the battery compartment off of the back of the device. Then, insert the batteries into the compartment according to the polarities indicated on the case. [1]
    • Place the battery door back over the compartment once you insert the batteries.
    • Note : Some models may take 2 AA batteries instead. [2]
    • The weather transmitter senses the temperature outside and displays it on the clock.
  2. Open the battery compartment on the back of the clock. Then, insert the batteries into the correct compartments based on the polarity marked on the clock. [3]

  3. Set the transmitter next to the clock; this helps it sync up with the clock. It may take up to 10 minutes before you see the outdoor temperature on the clock. [4]
    • If the outdoor temperature doesn’t display, remove the transmitter batteries and then the clock batteries. Wait 10 minutes and then reinsert the transmitter batteries and then the clock batteries.
    • Place the transmitter outside once the outdoor temperature is set. Put it in a dry, shaded location no more than 200 feet (61 m) away from the clock.
  4. Press and hold the “SET” button on the back of the clock. Wait for the time zone to flash and then use the “+” button to select the correct time zone. [5]
    • PST is Pacific Standard Time, MST is Mountain Standard Time, and CST is Central Standard Time.
    • Note : Some older models have a time zone switch on the back. Simply slide the switch to the correct time zone you’re in. [6]
    • The digital clocks are automatically set to EST, so skip this step if you are in EST.
  5. Once you put in the batteries, your clock starts searching for the WWVB signal that sets the date and time. The WWVB signal goes out every hour between 12 am to 6 am, so place the clock in a window and leave it there overnight so it can detect and receive the signal. [7]
    • Ensure the clock is at least 6 feet (2 m) away from TVs, computers, kitchen appliances, and other electronics. These devices can interfere with the signal.
    • Metal and concrete structures can also interfere with the WWVB signal.
    • The WWVB tower icon on the clock’s display starts flashing when it detects the signal.
    • When the clock receives the signal, the WWVB tower icon becomes permanently lit.
    • The WWVB signal is transmitted by the National Institute of Standards and Technology (NIST) in Fort Collins, Colorado. [8]
  6. If you want your clock to show the correct time while it’s searching for the WWVB signal, press and hold the “Set” button for 3 seconds to cycle through the manual settings. When the display flashes for each setting, use the “+” button to make changes. [9]
    • Press “Set” 2 times for daylight savings time (DST). You can turn DST off or on.
    • Press “Set” 3 times for the language. You can change the language to US (English), F (French), E (Spanish), or d (German).
    • Press “Set” 4 times to set the hour.
    • Press “Set” 5 times to set the minute.
    • Press “Set” 6 times to set the year.
    • Press “Set” 7 times to set the date.
    • Press “Set” 8 times to set the weekday.
    • Press “Set” 9 times for 12 or 24 hour time display. You can choose to set the time in regular time (12-hour clock) or military time (24-hour clock).
    • Press “Set” 10 times to set the temperature as Fahrenheit or Celsius.
    • To exit manual settings mode , press the “SNZ” button on the back of the clock.
    • The settings order may be slightly different for different clock models.
    • Note : Your manual settings will get overridden when your clock receives the WWVB signal.

  1. Find the battery compartment on the back of the clock. Then, lift up the compartment cover and insert the battery according to the polarity indicated on the compartment. Put the cover back on when you’re done. [10]
    • The compartment indicates the correct way to place the battery with a “+” or “-” symbol.
    • If your analog clock comes with a digital clock component on the back, insert 1 AA, 1.5-volt battery into the digital clock’s battery compartment. [11]
  2. On the back of the clock are 4 buttons for Pacific (PT), Mountain (MT), Central (CT), and Eastern Standard Time (ET). Simply press and hold the button for the time zone you are in. [12]
    • The SkyScan atomic clock can only collect the correct signal from 2,000 miles (3,200 km) away, so it must be set to the correct zone to get an accurate reading.
    • The clocks default to PST. If you are in PST, skip this step
  3. Set or hang the clock near a window to help it detect and receive the WWVB signal and sync to the correct time. The WWVB signal transmits every hour from 12 am to 6 am, so your clock will sync sometime during the night. [13]
    • Keep the clock 6 feet (2 m) away from TVs, computers, kitchen appliances, and other electronics as they can interfere with the WWVB signal.
    • Once the SkyScan clock picks up the signal from the NIST station, it will advance by eight seconds until it gets the right signal.
  4. While you wait for the clock to pick up the WWVB signal, feel free to adjust it to the correct time. Find the “Manual Set” button on the back of the clock. Press and hold it and watch as the hour and minute hands move. [14]
    • Release the button when the hands are in the correct position
    • Note : Once your clock receives the WWVB signal, it will override your manual settings.

  • Question
    What do the letters LUN mean on an atomic wall clock?
    Community Answer
    “LUN” may mean "set the clock to display the lunar (moon) phase." If it says “LON,” it means the time zone is set to show time in London, England, which is on Universal Coordinated Time (UTC).

      About This Article

      Article Summary X

      To set an analog SkyScan atomic clock, first press and hold the correct time zone button on the back. You can then set the hands manually, but they will adjust by themselves when the clock receives a signal. To set a digital SkyScan clock, press the time zone button or slide the time zone switch on the back. Then, press the plus button to cycle through time zones. If your clock has a switch for Daylight Savings Time, make sure this is on or off. Once you’ve set the time zone, you can manually set the time with the plus and set keys, but it will adjust automatically when it receives a signal. Regardless of whether your clock is analog or digital, place it by a window away from any metal or concrete structures so it can pick up a signal from the station. Your clock should receive a signal once a day, usually at 2am. For more tips, including how to set a SkyScan clock with a weather station transmitter, read on!
