Atomic Clock; Set Time, Date & Units - AcuRite 615 Instruction Manual

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: 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
Press and hold the "SET" button, located on the back of the display unit, for
3 seconds 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:

You will automatically exit SET MODE if no buttons are pressed for 30 seconds.
