SETUP:
Lay the clock face down, on a clean soft towel or newspaper to
prevent scratching.
Open the battery cover. Insert a finger in each of the indentations at
the bottom of the battery cover. Push up then pull out to open the
cover.
Insert three “C” alkaline batteries according to polarity markings.
Do not press buttons for four minutes to allow the clock to search for a
WWVB signal. The tower icon will flash.
Note: If only the bottom of the tower icon is showing and the top of
the icon is not there or partially there, reposition the clock for better
signal reception.
When WWVB signal reception occurs, the time and date will set and
the tower icon will show solid above the seconds.
WWVB Radio Controlled Time
The NIST radio station, WWVB, is located in Ft. Collins, Colorado and
transmits the exact time signal continuously throughout the United States at
60 kHz. The signal has a range of up to 2,000 miles. However, due to the
nature of the Earth’s Ionosphere, reception is very limited during daylight
hours. The atomic clock will search for a signal every night when reception
is best.
The clock receives the time signal via its built-in antenna and adjusts
automatically to the selected time zone. Once the correct time is set,
the clock continues running with an internal quartz-controlled
mechanism.
The internal quartz-mechanism is very accurate; therefore, it does not
matter if the clock is occasionally, unable to receive the time signals.
When the tower icon flashes, but does not set the time or the WWVB tower
does not appear at all, take note of the following:
Recommended distance to any interfering sources like computer
monitors or TV sets is a minimum of 6 feet (2 meters).
Within ferro-concrete rooms (basements, superstructures), the
received signal is naturally weakened. In extreme cases, please place
the unit close to a window and/ or point its front or back towards the
Fort Collins, Colorado, transmitter.
During nighttime, the atmospheric disturbances are usually less
severe and reception is possible in most cases. A single daily
reception is adequate to keep the accuracy deviation below 1 second.
Note: On rare occasions, the atomic clock is not able to detect the WWVB-
signal (disturbances, transmitting distance, etc.); the time can be manually
set.
