[. . . ]  During nighttime, the atmospheric disturbances are usually less severe and reception is possible in most cases. A single daily reception is adequate to keep the accuracy deviation below 1 second. Note: On rare occasions, the atomic clock is not able to detect the WWVB-signal (disturbances, transmitting distance, etc. ); the time can be manually set. Set Time: The SET button will move through the program menu. [. . . ] Press the WAVE/+ button at any time to stop the signal search. Hold the WAVE/+ button for 3 seconds to initiate a signal search.   WWVB Radio controlled time The NIST radio station, WWVB, is located in Ft. Collins, Colorado and transmits the exact time signal continuously throughout the United States at 60 kHz. The signal has a range of up to 2, 000 miles. However, due to the nature of the Earth’s Ionosphere, reception is very limited during daylight hours. The atomic clock will search for a signal every night when reception is best. The WWVB radio station derives its signal from the NIST atomic clock in Boulder, Colorado. A team of atomic physicists continually measures every second of every day to an accuracy of ten billionths of a second a day. These physicists have Set Alarm Time: Press and release the SET button once to enter Alarm Mode. The letters AL will show in the seconds display.  HOUR: Hold the SET button for 3 seconds. Press and release the WAVE/+ button to select the hour. Press and release the SET button to confirm and continue.  MINUTES: The minutes will flash. Press and release the WAVE/+ button to select the minutes. Press and release the SET button to confirm and exit. Activate/Deactivate Alarm: In Alarm Mode press and release the WAVE/+ or DST/- button to switch the alarm on or off. When the alarm is ON the alarm icon will appear between the hours and the minutes. When the alarm is OFF the icon will disappear. Snooze function: Press the SNOOZE button when the alarm beeps and the alarm will become silent and sound again in 5 minutes. The snooze icon will flash when the snooze function is active. While the snooze feature is active, press any button other than SNOOZE to deactivate the snooze function. Low Battery Indicator: When the low battery indicator appears in front of the indoor temperature, install a fresh alkaline battery.
