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.
•
Use Alkaline batteries.
•
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.
