Atomic Clock (RCC)
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.
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 clock.
Intelli-Time Technology
Clocks equipped with Intelli-Time technology store settings and instruct the time
and date to set themselves after loss of power or changing batteries.
Set the Time, Date & Units
The clock will immediately begin searching for the atomic signal after batteries
are installed. After the clock acquires the signal or completes its search
(approximately 3 minutes), you may manually adjust the time, date and units.
Press and HOLD the “SET” button located on the back of the clock for 2-3
seconds, to enter SET MODE. Once in SET MODE the preference you are
currently setting will blink on the clock.
To adjust the currently selected (ashing) item, press and release the “ ” or
“ ” buttons (press and HOLD to fast adjust).
To save your adjustments, press and release the “SET” button to adjust the next
preference. The preference set order is as follows:
TIME ZONE (PST MST CST EST AST HAST AKST)
ATOMIC CLOCK ON/OFF
DAYLIGHT SAVING TIME ON/OFF*
CLOCK HOUR
CLOCK MINUTE
CALENDAR YEAR
CALENDAR MONTH
CALENDAR DATE
TEMPERATURE SCALE (ºF or ºC)
You will automatically exit SET MODE if no buttons are pressed for 10 seconds.
Enter SET MODE at any time by pressing the “SET” button.
*If you live in an area that observes daylight saving time, DST should be set to
ON.
