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.

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 clock.

While in current time display mode, press the " " button to toggle between

between degrees Fahrenheit (°F) or degrees Celsius (°C) indoor temperature.

Set the Time & Date

Press and release the CLOCK ADJUST button, located on the front of the clock,

to enter the SET MODE. Once in SET MODE the preference you are currently

setting will blink on the clock.

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 CLOCK ADJUST button to

adjust the next preference. The preference set order is as follows:

12hr/24hr

TIME ZONE (PST MST CST EST AST HAST AKST)

CLOCK HOUR

CLOCK MINUTE

CALENDAR MONTH

CALENDAR DATE

CALENDAR YEAR

You will automatically exit SET MODE if no buttons are pressed for 5 seconds.

Enter SET MODE at any time by pressing the CLOCK ADJUST button.

* To set DST, use the DST ON/OFF switch located in the battery compartment.

If you live in an area that observes daylight saving time, DST should be set to

ON.
