Set The Time, Date & Units; Backlight Settings - ACU-RITE 01121 Instruction Manual

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.
