User's Manual

Inside or near concrete/ steel buildings
or structures, unless the clock is close/
next to a window (with curtain open).
Too close to household appliances
(Computer, TV, video/audios, fax
machines, speakers).
Near construction sites, traffic lights,
roadside, neon lights etc.
Inside moving vehicles (automobile, train, airplanes
etc) which radio transmission or electronics will
interfere the reception of atomic clock.
Next or close to power station.
Environmental Reception effects:
The Atomic Clock obtains the accurate time with wireless technology. Same as all wireless
devices, the receiving ability may be affected by, but not limited to, the following
circumstances:
•
Long transmitting distance.
•
Nearby mountains and valleys.
•
Among tall buildings.
•
Near railway, high voltage cable. etc.
•
Near freeway, airport, etc.
•
Near construction site.
•
Inside concrete buildings.
•
Near electrical appliances.
•
Near computers and televisions.
•
Bad weather locally or electrical storms between you and Colorado.
•
inside moving vehicles.
•
Nearby metallic structures.
Location Precautions
This clock receives a radio wave much like a TV or radio. Be sure to locate it near a window or some other
locations where reception is good. Avoid the following location,which can interfere with proper reception.
Synchronization signal reception can be received in Continental USA only. In other areas, you can still use
this clock by making time settings manually.

The ATOMIC Clock
With the Atomic Clock, you have the most accurate timepiece within the
continent. It can receive the time signal transmitted by the National
Institute of Standards and Technology (NIST), which is regulated by 3
atomic clocks and deviates less than 1 second within 3,000 years. The NIST
broadcasts the time signal (WWVB, 60kHz) continuously from Fort Collins,
Colorado. This signal can be received anywhere in the continental USA that long
wave (AM) radio reception is possible with a portable radio. It is expected
that the signal can cover a distance of over 2,000 miles from the transmitter.
Therefore, your clock will receive the signal within the broadcast range
anywhere an AM signal can be received; generally the signal cannot be
picked up in massive metal and concrete structures unless near a window.
In addition, some environmental effects (see next page) may affect the
transmitting distance.
For more information, please study the WWVB WEB page of NIST at:

Close to or on top of metal surfaces / plates.
