Changing The Lithium Battery
Like all batteries, eventually the built in lithium battery will need to be replaced. A number of factors, such as, the length of time between the date the radio was manufactured and the date you plugged it in for the first time determine the amount of time before replacement. During this initial storage period, the lithium battery is supplying power to the SmartSet® computer memory. Once you plug the radio in, your household outlet supplies the power, and the battery is not being used. A fresh lithium battery can supply power to the SmartSet® computer for at least 3 years even if it is never connected to an AC power supply. If your radio was connected to your AC supply within a few months after it was manufactured, and you experience only the normal, nuisance type, short duration power interruptions, your battery may last for up to 5 years or even longer.
When the battery power drops below a certain level, the 
indicator will ‘flash’. When you see this indicator, you should change the battery as soon as it is convenient for you to do so. To change the battery proceed as follows:
1.) Purchase a replacement 3V lithium battery wherever batteries are sold. The battery type is CR2430 or equivalent.
2.) Remove the battery from its package so it is ready to install.
Important: Leave the radio power cord connected to your AC outlet. This will provide power to the SmartSet® computer memory while the original lithium battery is removed.
3.) Turn the radio upside down and use a small screwdriver to remove the screw securing the battery holder to the cabinet.
BE CAREFUL NOT TO LOSE THIS SMALL SCREW!
