Instruction Manual
13.5” Atomic Wall Clock
Get Started
Step 1: Slide the switch to select a time zone.
Step 2: Insert 1 fresh AA, LR6 1.5 volt ALKALINE battery according to the
polarity marked on the case.
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 position and for the radio signal. search
If the radio signal is not received in the first 10 minutes, the clock will start
running from the 12:00 position and will continue to run. Do not attempt to
reset the hands manually even though the time on the clock is incorrect. The
clock is synchronizing to the WWVB signal and once the radio signal is decoded,
the hands will automatically adjust to the correct time. This may take up to 5
nights.
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.
Re : set
If the clock does not respond to the various function modes, reset the clock by
pressing the RESET button on the movement case.
Note: We recommend that you change the battery every 24 months to maintain
accuracy. Remove the battery when the clock will not be in use for an extended
period.

Manual Set Time
On rare occasions in certain areas, the clock
may not be able to utilize the radio controlled
function because of 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:
1. Press and hold the SET button for 3+ seconds to activate the manual mode.
Once the clock is in manual mode, there are two ways to move the minute
hand forward.
2. Hold the SET button down to move the minute hand forward consistently.
3. Alternatively, press the SET button rapidly (more than once per second) to
move the minute hand forward step by step (in minute increments).
4. Use these features to move the minute hand forward until the correct time is
set. The clock will automatically leave manual mode after the SET button is
not pressed for 6+ seconds.
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 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.
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 slide the DST switch
OFF. To reactivate the DST program simply slide the switch to the ON position.

Manual WWVB Time Signal Search
For information about WWVB, visit: 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 movement
will attempt to enforce a signal receipt from Fort Collins, CO.
• If the movement successfully receives the signal, the clock will reset
automatically to the correct time. The enforced signal receipt takes
approximately 3-8 minutes. If the clock still fails to receive the signal while in
the WAVE mode, the clock will automatically leave the WAVE mode.
• Set the clock manually and the movement's micro CPU will control the time -
keeping function.
Internal Synchronization:
Once the clock has set correctly by the radio signal, the clock’s CPU operates
continuously. To ensure accuracy, the clock synchronizes the position of the
second and minute hands to the time calculated by the CPU every day. Second
hand synchronization occurs at 1:30 a.m. and 9:30 a.m. and minute hand
synchronization occurs between 1:50 and 2:01 am every day.
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.
Frequently Asked Questions
Q. How long will the battery last?
A. A good AA alkaline battery will last over 24 months.
Q: Can I wire a control timing circuit to the La Crosse Technology® atomic clock?
A: No, the clock cannot work on a timing circuit. Opening the clock voids the warranty.
Q: Is there a booster antenna to receive the WWVB signal in a difficult location?
A: No, the clock cannot work with a booster antenna. Opening the clock or movement voids
the warranty.
Q: Can I shut off the WWVB signal?
A: No. If you manually set the time, when the clock receives a WWVB signal, that signal
will override the manual set. The WAVE button will temporarily stop a WWVB search, but
will not permanent stop the clock from receiving a WWVB time signal.
Q: Is there a version of analog clock with more than the four continental US times
zones?
A: La Crosse Technology® does not make an analog clock with more than four time zones.
These time zones are P (Pacific Time), M (Mountain Time), C (Central Time), and E
(Eastern Time).
