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 name brand Alkaline batteries for 

indoor displays

.  

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

  Use batteries 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 Digital Clock Factory Restart 

 
Explanation:

 The factory restart returns the Atomic Digital Wall Clock 

to an “out-of-the-box” state and often 

resolves an issue.
