The radio's battery voltage is automatically detected upon power-on. A "low battery" prompt will sound when the voltage drops. While you can continue to use it briefly, excessive transmission will quickly drain the remaining power. When the battery voltage becomes critically low, an error alarm will sound, and transmission will be disabled. At this point, charge or replace the battery pack.
