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.
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: 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 the “SET” button 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 “
▲
” or
“

” buttons (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:
TIME ZONE (PST MST CST EST)
DST (Daylight Saving Time ON or OFF)*
CLOCK HOUR
CLOCK MINUTE
CALENDAR MONTH
CALENDAR DATE
CALENDAR YEAR
UNITS: TEMPERATURE (ºF or ºC)
*If you live in an area that observes DST, DST should be set to ON, even if it is
not currently Daylight Saving Time.
You will automatically exit SET MODE if no buttons are pressed for 30 seconds.
Enter setup mode at any time by pressing the “SET” button.
