ATOMIC CLOCK OPERATION
The Sangean RCR1 consists of a crystal controlled clock movement
which includes a very special AM radio receiver that is tuned to
receive the 60kHz WWVB time signal broadcast from the U.S.
Government’s Atomic Clock in Boulder, Colorado. The signal is an
AM radio signal and as such is susceptible to weather conditions,
electrical interferences, solar conditions and the position of the
clock’s antenna all of which effects the receiver’s reception. As a
general rule, best reception is at night and just before or after sunrise
or sunset. Although the clock can work in most locations the number
of times that it adjusts itself to the U.S. Atomic Clock’s time signal
may depend on its location. Under certain weather conditions or in
areas of poor reception it may take 48 hours or more to receive a
signal for the correct time. In some cases it may be necessary to
seek another location in order to receive a useable time signal.
Set time Zone Switch [10] located on bottom of clock to your correct
zone as illustrated.
After the ATS program completes the AM/FM frequency set up the
following display — : — will appear and the symbol will blink
indicating the radio is searching for the radio controlled signal.
Once the radio receives the radio controlled signal the correct time
and date will be set automatically. Once the correct time and date
have been set, the symbol will stop blinking but the symbol will
remain on the display indicating that the time and date have been
set utilizing the radio controlled signal. The analog clock will follow
the radio controlled signal.
