Because a portion of the self-test requires battery power, the self-test will not be initiated if
the batteries are less than 90 percent charged. If the UPS detects a problem, LED 4 will be
solid red (see Figure 2-3), and the UPS sounds an audible alarm.
NOTE: See Chapter 5, "Troubleshooting," for information on what to do if the self-test detects a
problem.
