The wonderful advantage of owning a radio-controlled clock is that
it is virtually trouble free. If the clock receives a clear time signal, it
will set itself perfectly. If it does not receive a time signal, consider
the following:
Battery – The clock must have a fresh battery to receive and
process the time signal.
Location – Try a different location, ideally near a window that
faces Colorado.
Weather – Electrical storms between you and Colorado
during the night will interfere with the WWVB signal.
Hands Spin- When the hands spin about the same time every
day the clock is auto-correcting the time. The hour hand
should not spin more than twice around the clock. Hands may
spin if the battery is under powered or over powered.
The National Institute of Standards and Technology and WWVB
encode a special DST "bit" in the WWVB transmission for DST.
Your clock will read this information and automatically advance the
hands one hour in the spring and eleven hours in the fall.
If you live in an area that does not recognize DST, you must slide
the DST switch OFF. To reactivate the DST program simply slide
the switch to the ON position.
Manual WWVB Time Signal Search
For WWVB information: www.nist.gov/pml/div688/grp40/wwvb.cfm
Manual Signal Search:
The WWVB signal is strongest at night.
Hold the WAVE button down for 3+ seconds.
The hands will automatically reset to the 12:00 position, and
the clock will search for the WWVB time signal.
If the clock receives the signal, the clock will set automatically
to the correct time. The signal search takes approximately 3-8
minutes.
Set the clock manually, and the movement's micro-CPU will
control the time keeping function.
