INTRODUCTION
The Model 1500E
Using the same technology NASA employs to tell time, the Model 1500E wirelessly
synchronizes with the National Institute of Standards and Technology's atomic
clock in Boulder, Colorado. In addition to confirming the time daily, the 1500E
automatically adjusts for Daylight Saving Time. No wires, no worries, and no more
excuses for being late.
About Your Atomic Clock
In addition to a regular quartz time clock, the Model 1500E contains an antenna
and a microchip. The antenna receives the official time signal from the US
Government's National Institute of Standards and Technology and the microchip
translates the time signal and adjusts the time display to the correct time. The
Model 1500E receives a 60-kilohertz, low frequency AM radio signal from the
WWVB radio station maintained by the National Institute of Standards and
Technology (NIST). The NIST, using its atomic clock, is the official timekeeper for
the US and is located in Boulder, Colorado. The Model 1500E will work anywhere
it can receive the WWVB signal from the NIST. This signal is broadcast to reach
across the continental US and into parts of Canada and Mexico. To learn more
