A battery is only used in assistant control panels that have the
clock function available and enabled. The battery keeps the clock
operating in memory during power interruptions. The expected
life for the battery is greater than ten years. To remove the battery,
use a coin to rotate the battery holder on the back of the control
panel. Replace the battery with CR2032.
