BATTERIES 

 

Explanation:

 Many problems are resolved with fresh batteries of the appropriate 

voltage. Many items sent in under warranty work when tested with fresh batteries. 

Batteries manufactured this year will have an expiration date 10 years (or more) in the 

future. Battery technology has improved and batteries will maintain voltage longer in 

storage. However, the environment the batteries reside in for the 10 years can deplete 

the power. 

 

  We suggest a name-brand Alkaline battery.  

  A minimum voltage of 1.48V is necessary for proper performance.   

  Use a battery dated at least six years in advance of the current year. Batteries dated 

earlier than six years from now may still work, but may be unstable in performance.   

  Good name-brand batteries make less noise, which reduces the chance of RF (radio 

frequency) interference from the battery compartment.  

 

ATOMIC CLOCK FACTORY RESTART 

 

Explanation:

 The factory restart returns the atomic clock to an “out-of-the-box” state 

and often resolves an issue.  

  

Factory Restart: 

1.  Remove the battery from the clock for 15 minutes.  

2.  Press the Set button at least 20 times to clear all memory.  

3.  Slide the switch to select a time zone. 

4.  Insert 1 fresh AA, LR6 1.5 volt ALKALINE battery according to the polarity marked 

on the case. 

5.  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 clock does not receive the radio signal 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. 

 

SUPPORTED TIME ZONES 

 

  This atomic clock offers 4 time zones: Pacific, Mountain, Central and Eastern. Use 

the selector bar to choose your time zone. 

  La Crosse Technology

®

 does not make an analog clock with more than four time 

zones.  

  The atomic clock works in North America.  

  Outside of North America, the atomic clock will not receive a WWVB signal, but will 

keep time like a quartz clock if manually set.
