CK31 Status Lights
The battery light and the battery screen icons work with each
other to alert you to the status of your battery. If the battery
light comes on, check the taskbar to see which battery icon
appears on it. Use the CK31 Screen Icons table on page 17 to
help determine when you need to replace your battery.
