20 “ Atomic Wall Clock
Get Started
Step 1: Insert 1 fresh “C”, LR14 1.5 volt ALKALINE battery
according to the polarity marked on the case.
Step 2: Firmly press the time zone button once.
Step 3: Position the clock on an exterior wall that faces Ft.
Collins, Colorado. During the night, your clock will
automatically set itself.
Note: The hands will move to the 12:00, 4:00 or 8:00
position and search for the radio signal. If the radio
signal is received the time will set. If the signal is not
received the clock will stay at the 12:00, 4:00 or 8:00
position and search for the WWVB time signal on the
even hours. Once the radio signal is decoded, the hands
will automatically adjust to the correct time. This may
take up to 5 nights.
Step 4: The default time zone is Pacific Time. If the clocks sets
itself and the hours are off, hold the correct time zone
button for 5 seconds to correct.
Position Clock
Choose a location 6 feet or more from electronics such as
cordless phones, wireless gaming systems, televisions,

microwaves, routers, baby monitors, etc., which can
prevent signal reception.
Position near an exterior wall that faces Ft. Collins, Colorado
for WWVB time signal reception.
The antenna is available for signal reception when the front
or back of the clock faces Colorado.
Manual Set Time
On rare occasions in certain areas, the clock may not be able to
receive the radio controlled time signal due to the strength of
the signal or the geographic location. In this case, the clock
can be set manually and used as a regular quartz wall clock.
Note: Allow up to five nights for the clock to receive the WWVB
signal before manually setting the time.
Set the clock manually:
On rare occasions it is not possible to receive a WWVB signal at
the location of the clock. In this instance the clock may be set
manually and will operate as a quartz clock.
1. Press and hold the Q-Set Button on the backside of the
movement until the second hand starts running.
2. Release the button quickly (less than 3 seconds) and press
it again to set actual time.
3. Three seconds after releasing the Q-Set Button your clock
will start working as a Quartz Clock.
4. In Quartz Mode your clock will try to receive each even
hour. If a signal is received it will override the manual set
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 clock will read this information and automatically advance
the hands one hour in the spring and eleven hours in the fall.
Arizona: If you live in an area that does not recognize DST,
you must press the DST button one time only to turn OFF.

Signal Interference
In some cases, the signal is affected by weather conditions and
electrical interferences, or the location of the clock itself may
result in poor reception. If the clock has not synchronized to the
correct time within a few days of activation, you may need to
move the clock to a different location.
Auto Correction
The clock automatically checks its hands position daily between
3:00 and 4:05 (pm). If hands position is not equal to internal
time, the hands are driven (quick run) to the correct time
again. You will see the hands spin completely around during
this correction. This is normal behavior.
Frequently Asked Questions
Q. How long will the battery last?
A: A good “C” 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 this La Crosse Technology clock be used
outdoors?
A. No. Outdoor use is not recommended for this clock.
www.lacrossetechnology.com/support Page | 4
Operating range is 23 to 131 degrees Fahrenheit.
Q. Can this La Crosse Technology clock be wired to
control timing circuits?
A. No. Modifications to the clock will void the warranty.
Q: This movement cannot receive, but other movements
have reception inside same room.
A: Check battery voltage. 1.48-1.7 volts are best for optimum
performance.
A: Check that the clock is not within 6 feet of TV-sets,
monitors, telephone-sets or other items that may cause
interference.
Q: Is there a booster antenna to receive the WWVB
signal in a difficult location?
A. No. Modifications to the clock will void the warranty.
Q: Clock spins continually. It does not stop (more than
4min).
A: Check battery voltage. 1.48-1.7 volts are best for optimum
performance.
Q: Hands stop on 4:00, 8:00 or 12:00 forever.
A: This is normal restart behavior for the clock. The hands will
spin to 4:00, 8:00 or 12:00 and not move until the WWVB
signal is received. This may take up to five nights dependent on
interferences.
Q: Clock receives the WWVB signal, but shows wrong
time.
A: Check if correct Time Zone is selected. Hold the correct
time zone button for 5 seconds and the hands should correct.
A: Check battery voltage. 1.48-1.7 volts are best for optimum
performance.
A: Locate the bronze colored pins in the upper left region of the
movement on the back of the clock. Short across the pins
briefly with a screwdriver or similar metal object and allow the
hands to spin. The hands will stop all pointing at 12 if they are
properly aligned. Allow the clock to receive a signal and set
itself. Then select the correct Time Zone for your area.
Q: Battery was removed and put in again, but the
www.lacrossetechnology.com/support Page | 5
movement does not restart and the hands do not spin.
A: Remove the battery and press the Q-Set button 20 times to
discharge electricity. Leave the battery out for 15 minutes.
Install a fresh C LR14 alkaline battery. The hands should sin to
4, 8 or 12 o’clock.
A: Check battery voltage. 1.48-1.7 volts are best for optimum
performance.
Troubleshooting
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 Alkaline battery to
receive and process the time signal.
Location: Try a different location, ideally near a window.
Your clock 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.
