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
The display unit will automatically start in SET mode after batteries have been
installed. Enter SET mode at any time by pressing the “SET” button, located
on the back of the display unit. 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 AST HAST AKST)
DST (Daylight Saving Time ON or OFF)*
CLOCK HOUR
CLOCK MINUTE
CALENDAR MONTH
CALENDAR DATE
CALENDAR YEAR
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.
* If you live in an area that observes Daylight Savings Time, DST should be set
to ON, even if it is not currently Daylight Savings Time.
Select Degrees Fahrenheit or Celsius
To select between degrees Fahrenheit (ºF) or Celsius (ºC) temperature units,
press the “ºF/ºC” button located on the back of the display unit.
