has devised accurate machines to trap and measure time. Today, time is precisely measured in the
United States by the most accurate clock in North America, the Atomic Clock of the US National
Institute of Standards and Technology, Time and Frequency Division in Boulder, Colorado. A team of
atomic physicists continually measures every second of every day to an accuracy of ten billionths of a
second per day. These physicists have created an international standard, measuring a second as
9,192,631,770 vibrations of a Cesium 133 atom in a vacuum. This atomic clock regulates the WWVB
radio transmitter located in Fort Collins, Colorado, where the exact time signal is continuously broadcast
throughout the United States at 60 kHz to take advantage of stable long wave radio paths found in that
frequency range. Radio waves at these low frequencies use the earth and the ionosphere as a waveguide and follow the curvature of the earth for long distances.

SET UP INSTRUCTIONS
To set up your clock simply install one fresh AA, LR6 ALKALINE battery. Due to the nature of
long-wave radio signals, it is normally not possible to receive a signal during the day so it is best to
install the battery late in the evening. Once the battery is installed, the clock will begin searching for a
signal. For the initial setting, it is recommended to stand the clock in an upright position near a window.
Within five minutes the clock will either receive the WWVB signal and set itself to the exact time (for the
default Pacific Time Zone), or it will determine that the signal is not receivable at its current location and
time of day. If a signal is not receivable, it will fast-forward the hands to the 4, 8, or 12 o’clock position
and search for WWVB every two hours until a signal is received. If the time is manually set, the clock
will continue to periodically search for a signal and automatically reset the hands when the signal is
received.
Once the clock has set to the correct time (default Pacific Time Zone)
If you are in the Pacific Time Zone- you are ready to hang your clock.
If you are not in the Pacific Time Zone, select your time zone by pressing one of the four time zone
buttons PT-Pacific Time, MT-Mountain Time, CT-Central Time, ET-Eastern Time. If multiple buttons are
pressed, the clock will set to the time zone selected last. If no time zone is selected the clock will
default to Pacific Time. Your clock can only set itself to one of the four time zones stated above. For
time zones outside of PT, MT, CT or ET you must manually set the time using the Manual Time set
button on the back of the movement. Our clock will set to the correct Time Zone that you selected. Once
the clock has reached the correct time, you are ready to hang your clock.
ONCE THE CLOCK HAS SET TO THE DEFAULT PACIFIC TIME ZONE, YOU MUST PRESS
THE CORRECT TIME ZONE BUTTON.
The clock is designed for indoor use only. Select a location to place your radio-controlled clock
where it will be at least six feet away from a TV, computer, air conditioner or other household electrical
appliances. The optimal location is near a window. Windows facing Colorado provide the best signal.
The WWVB time signal will easily penetrate masonry and wood framed buildings. WWVB will
penetrate almost every residential building and most steel buildings if they have adequate windows. It
is not possible, however, for WWVB to penetrate most indoor shopping malls and rooms in the center of
large office buildings that do not have windows. In buildings that WWVB cannot penetrate, you may set
the time using the manual time set button. When the clock receives the WWVB signal it will
automatically set the hands to the exact time.

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

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
Location - Try a different location, ideally near a window. It should be at least six feet from
Weather - Electrical storms between you and Colorado during the night will interfere with the

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
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

If you live in an area that does not recognize DST you must press the (unmarked) DST button for one
second to deactivate your clock’s DST program. To reactivate the DST program simply press the DST
button again for one second.
POSITIONING THE ANALOG CLOCK:
Before wall mounting, please check that the WWVB signal can be received from the desired location. To
wall mounting:
1. Fix a screw (not supplied) into the desired wall, leaving the head extended out by about 3/16"
(5mm).
2. Hang the Analog clock onto the screw. Please remember to ensure it locked on the place
before releasing.
FREQUENTLY ASKED QUESTIONS
Q. How long will the battery last?
A. A good AA alkaline battery will last over one year. If your clock is located in an area with little
interference where it can quickly receive a signal, the battery can last much longer than one year.
Q. Can the clock be wired to control timing circuits?
A. No.
Q. Why does the second hand move only once every 2 seconds?
A. When the battery drops below 1.25 volts the clock indicates that it is time to change the battery by
advancing the second hand in 2-second steps. The operating voltage range is 1.25 to 1.75 volts.
CARE AND MAINTENANCE:
• Extreme temperatures, vibration and shock should be avoided as these may cause damage to
the units and give inaccurate forecasts and readings.
• When cleaning, use a soft damp cloth only. Do not use solvents or scouring agents as they
may mark the casing.
• Do not submerge the unit in water.
• Immediately remove all low powered batteries to avoid leakage and damage. Replace only
with new batteries of the recommended size.
• Do not make any attempts to repair the unit. Return it to its original point of purchase for repair
by a qualified engineer. Opening and tampering with the unit may invalidate its guarantee.
• Do not expose the unit to extreme and sudden temperature changes, as this may lead to rapid
changes in forecasts and readings and thereby reduce its accuracy.
BATTERIES CHANGE:
For best performance, batteries should be replaced at least once a year to maintain the best running
accuracy. Ensure that the batteries used are new and the correct size.
