<p><b>What Should I Pay Attention to When Using WWVB Features?</b></p><p>Please select the correct time zone before RCC search.<br>Make sure your location can successfully receive the time signal, place the clock in an open place or near a window with good signal.<br>Please place the device more than 3.28 feet away from sources of interference such as TVs, computer, microwave, radio, etc.<br>Closed areas such as airports, basement, factories and areas, in which reinforced concrete was used in the walls, are not recommended.<br>If the RCC time signal is not received successfully and the time automatic setting fails, you can also cancel the radio reception and set the time manually.<br>Sometimes in extreme weather or weak signal or other disturbances appear nearby, the clock may also appear to receive the wrong time signal instruction.For more information, please refer to the WWVB web page of NIST.<br>After 48 hours, if the clock hasn't received the signal, or if you have any queries, problems or do not understand any parts of these instructions, please write to us.</p><p><b>How do atomic clocks work?</b><br>Atomic clock is an extremely accurate timepiece. Most atomic clocks in north america use WWVB's transmissions to set the correct time automatically. They can receive the time signal transmitted by the national institute of standards and technology (NIST). The NIST broadcasts the time signal (WWVB,60KHz) continuously from Fort Collins, Colorado. It is expected that the signal can reach a distance of over 2,000 miles from the transmitter. The atomic clock has a built-in RCC receiver for automatic synchronization of WWVB radio broadcasts. Atomic clocks will always be accurate to within one second when receiving daily WWVB updates.</p><p><b>GREAT GIFT IDEA</b><br>With beautiful packaging, good design and a variety of great features, this digital wall clock is the perfect gift for parents, friends, heavy sleepers or light sleepers.
