and turned ON.

"POWER" LED: this green LED lights continuously when the UPS is
ON and supplying connected equipment with AC power from a utility
source. The LED flashes and an alarm sounds (4 short beeps followed
by a pause) to indicate the UPS is operating from its internal batteries
during a blackout or severe brownout. If the blackout or severe
brownout is prolonged, you should save files and shut down your
equipment since internal battery power will eventually be depleted.
See "BATTERY CHARGE" LED description below.
"VOLTAGE CORRECTION" LED: this green LED lights continuously
whenever the UPS is automatically correcting high or low AC voltage
on the utility line without the assistance of battery power. The UPS will
also emit a slight clicking noise. These are normal, automatic
operations of the UPS, no action is required on your part.
"OUTPUT LOAD LEVEL" LEDs: These multicolored LEDs indicate the
approximate electrical load of equipment connected to the UPS's AC
outlets: green (light load), yellow (medium load) and red (overload). If
the red LED is either illuminated continuously or flashing, clear the
overload immediately by unplugging some of your equipment from the
outlets until the yellow or green LED illuminates. CAUTION! Any
overload that is not corrected by the user immediately may cause the
UPS to shut down and cease supplying output power in the event of a
blackout or severe brownout.
"BATTERY CHARGE" LEDs: When the UPS is operating from utility
power, these LEDs indicates the approximate charge state of the
UPS's internal batteries: red indicates the batteries are beginning to
charge; yellow indicates the batteries are roughly midway through
charging; and green indicates the batteries are fully charged. When
the UPS is operating from battery power during a blackout or severe
brownout, these multicolor LEDs indicate the approximate amount of
energy (ultimately affecting runtime) that the UPS's batteries will
provide: red indicates a low level of energy; yellow indicates a medium
level of energy; and green indicates a high level of energy. Since the
runtime performance of all UPS batteries will gradually deplete over
time, it is recommended that you periodically perform a self-test (see
"MUTE/TEST" Button description) to determine the energy level of your
UPS batteries BEFORE a blackout or severe brownout occurs. During a
prolonged blackout or severe brownout, you should save files and shut
down your equipment since battery power will eventually be depleted.
When the red LED illuminates and an alarm sounds continuously, this
indicates that the UPS's batteries are nearly out of power and UPS
shutdown is imminent.
