Atomic Clock
AcuRite atomic clocks use a radio-controlled signal (RCC) 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.
The 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: Signal reception is normally better at night and when the weather is clear.
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 & Units
Press and release the "SET" button, located on the front of the display, 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 and release the "

"

To save your adjustments, press and release the "S E T " button again to adjust the next

CALENDAR MONTH
CALENDAR DATE
CALENDAR YEAR
TEMPERATURE UNITS (ºF or ºC)
BAROMETRIC PRESSURE UNITS (hPa or inHg)
RADIO CONTROLLED CLOCK FUNCTION (ON or OFF)
*If you live in an area that observes Daylight Saving Time, DST should be set to ON,
even if it is not currently Daylight Saving Time.
You will automatically exit SETUP MODE if no buttons are pressed for 10 seconds. Enter
setup mode at any time by pressing the "SET" button.
