“OVERLOAD/CHECK BATTERY” LED: this red LED lights continuously after a self-
test to indicate the capacity of the battery-supported outlets has been exceeded.
To clear the overload, unplug some of your equipment from the battery-supported
outlets; then use the ON/OFF/TEST button to run a Self-Test. If the UPS continues to
detect an overload, remove more equipment and repeat the self test until successful.
