During the search for the WWVB signal, the wave
will keep flashing. The flashing icon indicates that the radio
control circuit is working; the larger the circle, the stronger the signal. Other buttons will not function except
WAVE/+/MONTH/HR button at this time. Press WAVE/+/MONTH/HR button to stop reception manually.
Radio control feature
The National Institute of Standards and Technology (NIST) is located in Fort Collins, Colorado. The NIST
continuously broadcasts the time signal (WWVB, 60KHz) which can be received anywhere in the continental United
States and parts of Canada where long wave (AM) radio reception is possible. The signal can reach approximately
2,000 miles through the internal antenna in the Radio Controlled Clock. However, due to the nature of the Earth’s
atmosphere, reception is very limited during daylight hours. The radio controlled clock will automatically search for a
signal every night when reception is best.
The WWVB radio station delivers its signal from the NIST Atomic Clock in Boulder Colorado.
Possible reception interference sources
All radio-receivers of the radio-controlled clock may be subject to certain interference. Interference can be caused by a
thunderstorm or metallic elements in buildings (such as-windows with metal frames), domestic appliances, TV sets and
PCs. Moreover, the transmitter may shut off temporarily.
If your alarm clock cannot receive the transmitter signal, change the location of the alarm clock.
If reception is interfered, hold the button WAVE/+/MONTH/HR continuously until the signal search is started or the
time is set manually.
Time update
1)
The clock will automatically update its time everyday at 01:00AM and 01:00PM. It will make another attempt the
next hour if the signal isn’t received.
2)
Reception can start anytime by pressing the WAVE/+/MONTH/HR button.
Important:
It is recommended to place the Radio controlled clock near a window. Please move the clock to another location if
difficulty in signal reception is encountered.
