Atomic Clock Technology

Follow

AcuRite atomic clocks use a radio-controlled signal to synchronize to the correct time broadcast by the National Institute of Standards and Technology (NIST) Radio Station WWVB, located near Fort Collins, Colorado. WWVB broadcasts the current time and date with split-second accuracy. Atomic clocks set themselves and automatically adjust for daylight saving time (DST) to provide the most accurate timekeeping standard possible.

 

If your Atomic Clock:

  • Is inaccurate
  • Loses or gains time
  • Does not update after a power loss
  • Does not update for Daylight Savings Time
  • Does not sync with the Atomic Signal
  1. Check to make sure you have selected the correct time zone with the Daylight Savings Time set correctly for your location. (Most locations will require DST set to ON.) 
  2. Make sure you are using fresh, standard alkaline batteries from a high-quality brand. We do not recommend using rechargeable or heavy-duty batteries.
  3. An atomic unit should automatically correct itself with the date and time once it picks up the Atomic Signal. Try moving the unit to a window facing Colorado overnight (signal is better at night) so it can gain a strong connection.
  4. If it continues to change, you may want to relocate the unit to a different location in your home. For additional troubleshooting, please visit:
