OPERATION
Battery Mode
When the UPS is operating during a power outage, the alarm beeps once every 10 seconds and the 
button, the μ, and 
indicators
are on. The 
bar graph indicators show the level of remaining battery power.
When utility power returns, the UPS transfers to Normal mode operation while the battery recharges.
If battery capacity becomes low while in Battery mode, the alarm beeps every three seconds. Immediately complete and save your work to prevent data loss and similar difficulties.
When utility power is restored after the UPS shuts down, the UPS automatically restarts.

NOTE For 230V models, the output receptacles may remain electrically live (up to 115V).
