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.
