This talking clock combines the classic look of an analog clock face with the convenience of having the current time announced at the touch of a button and of never having to set the clock. The Reizen Talking Atomic Analog Alarm Clock is an ideal low vision aid clock makes it easy to see and use. Touch the large button on top of the talking clock once to hear the current time announcement in a clear male voice and activate the LED backlight. Touch it again to hear the day and date. This talking clock receives a daily radio signal from the NIST Atomic Clock in Colorado that keeps it accurate to the millisecond and even accounts for Daylight Savings Time. Just set your time zone when you first receive the talking analog clock, and it has all automatic from there on. You will never again have to set it - ever. Note: Radio signal may not be received in all locations (including Alaska and Hawaii). In this case, the time can be set manually, however, the day and date functions will not operate. About the Radio Signal (Atomic Function): The radio signal that controls the time, day of the week and date is broadcast through a radio station in Fort Collins, Colorado. The National Institute of Standards and Technology (NIST) operate the station, which is the U.S. Government agency that provides the nation's official time. Your watch is programmed to listen for the signal coming from this station overnight when it is strongest (at 3am, 4am, 5am and 6am daily) until the signal is received and your watch time is adjusted accordingly. You may also cue the watch to attempt to receive the signal on demand. Reizen Talking Atomic Analog Alarm Clock Important Notes: - Global signals are available in the USA (WWVB), Germany (DCF), the UK (MSF) and Japan (40/60Khz) upon request. There is no Atomic Clock signal available in Australia. - The atomic function and calendar will not operate in Alaska or Hawaii because the watch cannot communicate with the National Institute of Standards and Technology from these states. However, it may still be used in those two states - and in countries where there is no atomic signal - as a regular 'manual-set' watch. Not to be sold in Canada and Europe.
