*DST (Daylight saving time) ON/OFF button
Pressing DST-ON/OFF button during DST the clock will switch to time without daylight saving. Pressing
it again DST will be activated again. In areas where no DST is used you may deactivate DST by
pressing the DST-OFF switch.
SET THE TIME USING THE MANUAL TIME SET BUTTON
In some cases, the clock may not receive the WWVB signal due to atmospheric disturbances or hard to
reach locations such as inside shopping malls. In this case, please use the Manual Time Set button,
located at the back of the clock to manually set the time. To do this:
1.
Press and hold the Manual Set button. The second hand will move to the 12 position.
2.
Release the Manual Set button and again press and hold the Manual Set button. The minute and
hour hands will fast-forward while the button is held.
3.
Keep holding the Manual Set button until the time is set as required.
4.
Release the button. About 3 seconds later, the second hands will start to move and the clock is
now running with manual time.
Note:
When the clock displays manual time, it will continue to try to receive the WWVB signal at each of the
even numbered hours: 0:00, 2:00, 4:00, 6:00 … 20:00 & 22:00.
TROUBLESHOOTING
The wonderful advantage of owning a La Crosse Technology radio controlled clock is that it is virtually
trouble free. If the clock receives a clear signal it will set itself perfectly. If it does not receive a signal
consider the following:
Battery
-
The clock should have a fresh Alkaline Battery to best receive and process the time
signal.
Location
-
Try a different location, ideally near a window. It should be at least six feet from
computers, TVs, air conditioners, other Radio Controlled clocks and other electrical
appliances that cause interference.
Weather
-
Electrical storms between you and Colorado during the night will interfere with the
WWVB signal. Although we cannot control the weather, we can help you predict it.
Reception
-
The clock seems to “take off” for no reason and then stopping at the same
time.
It is not uncommon for the clock to make a "correction", sometimes daily. This
happens
(ADD “s” TO HAPPEN)
if the clock gets ahead of itself by a fraction of
a second. To correct this the clock will advance a complete rotation the next time
it receives a signal.
Daylight Saving Time
The National Institute of Standards and Technology and WWVB encode a special DST “bit” in the
WWVB transmission for DST. Your La Crosse Technology clock will read this information and
automatically advance the hands one hour in the spring and eleven hours in the fall. If Congress
