Atomic Clock
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.
This AcuRite atomic clock and calendar will maintain the correct time and date,
and automatically update for daylight saving time to provide the most accurate
timekeeping standard possible.
Please note: The atomic signal generally takes a few hours to synchronize, so it is
important to manually set the time and date after powering on the display.
Set the Time & Date
Press AND HOLD the “SET” button for 5 seconds to enter SET MODE. Once in set
mode, the preference you are currently setting will blink on the display.
To adjust the currently selected (flashing) item, press the “ + ” button (press and
HOLD to fast adjust).
To save your adjustments, press and release the “SET” button again to adjust the next
preference. The preference set order is as follows:

You will automatically exit SET MODE if no buttons are pressed for 30 seconds. Enter
basic setup mode at any time by pressing and holding the “SET” button.
