3b) “BATTERY CAPACITY” Meter: This meter displays the approximate charge level (in 20% increments) of the UPS's internal battery. During a blackout or severe brownout, the UPS will switch to battery power, the “ON BAT” icon will be illuminated and the charge level will deplete.
3c) “AVR” (Automatic Voltage Regulation) Icon: This icon will illuminate whenever your UPS is automatically correcting AC line voltage without depleting battery power. This is a normal, automatic operation of your UPS, and no action is required on your part.

3e) “ON BAT” (On Battery) Icon: During a severe brownout or blackout, this icon illuminates and an alarm sounds (4 short beeps followed by a pause) to indicate the UPS is operating from its internal batteries. Monitor the “Battery Capacity” Meter to determine the approximate battery charge level available to support equipment. During a prolonged brownout or blackout, the alarm will sound continuously (and the “BATTERY CAPACITY” Meter will show one 20% capacity segment shaded) to indicate the UPS's batteries are nearly out of power; you should save files and shut down your equip- ment immediately.
