•Under the best conditions, receiving a strong signal with no interference, the clock will take at least 5 minutes to receive and decode the signal and display the correct month, date, day, and time. If you live in an area of poor reception and high interference it could take several hours, or even overnight, for the clock to set itself correctly. This is completely normal and not an indication of any problems with your unit. If you live in one of the difficult reception areas, please read all of the instructions very carefully, and please be patient.
•The best time for reception of the WWVB signal is the period between midnight and dawn, because interference from other sources tends to be lower during these hours.
•Reception of the Atomic Clock time signal may also be difficult in buildings with steel frames, such as high rise apartment or office buildings, which usually also have windows with steel frames, and buildings with steel roofs. Large amounts of steel may block reception of the signal.
