What is a Radio-Controlled Atomic Clock?
This atomic clock is an extremely accurate timepiece. It 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. This signal can be received anywhere in the continental USA and Canada. It is expected that the signal can reach a distance of over 2,000 miles from the transmitter.
This WallarGe atomic clock automatically receives the time signal every day at midnight and makes any required adjustments to the time setting. Simply insert the batteries provided with the clock and it will synchronize to the time set out by the atomic clock in Colorado once the signal is received. The clock includes all 4 time zones. The time and date can easily be set manually for those using the clock outside of North America. Daylight Savings Time on/off option is included. Fashionable sensory design, large LCD digits display and multiple visual angles make it suitable for all occasions: Banks, Schools, Churches, Offices, and Homes.
