La Crosse Technology Clock 404 1225 User Manual

Model: 404-1225  
Instruction Manual  
10” 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 search for the radio signal.  
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.  
Reset:  
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 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).

Q: Why do the hands spin?  
A: 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.  
A: Hands may spin if the battery is under powered or over powered. Use only Alkaline  
batteries in the clock.
