HOW DOES IT WORK?
This clock receives a time signal transmitted by the National Institute of Standard
and Technology (NIST). Located in Fort Collins, Colorado, the transmitter is linked
to a cesium atomic clock, the most accurate time keeping device in the world,
with a time deviation less than one second in one million years.
Your SEIKO clock is specially programmed to interpret the signal and set itself to
the correct local time.

COVERAGE
Continental United States, parts of Southern Canada and Northern Mexico.
Geographic features, weather disturbances and structural characteristics may
affect reception. Signal reception is strongest during night time.

LOCATION OF CLOCK
Place your clock near a window and in an area in your home or office where you
receive good radio reception.
Avoid placing the clock near electrical devices such as personal computers,
radios, TV's, satellite dishes, air conditioners, etc. Also, avoid light dimmer
switches and appliances with electric motors such as dishwashers, refrigerators
and washing machines. These devices may interfere with the reception of the
signal.
