Basic Operation
"REPLACE BATT" LED: This red light will illuminate constantly and the
UPS alarm will beep every 2 seconds if UPS microprocessor detects a
battery fault or if your UPS fails the automatic self-test (after you turn
your UPS ON) and the UPS battery is less than fully charged. Let the UPS
system charge for at least 12 hours and perform a self test using the
"ON/TEST Button" as described on page 7. If the light continues to stay
on, contact Tripp Lite for service.

a power outlet.
