Specifications
The On/Off button flashes once
per ½ second, and the Back-
UPS beeps once per second at
the same time.
Battery capacity is low (there are
about 2 minutes of runtime
remaining).
The unit is about to shut down due to a low
battery charge condition. When the unit beeps
once every second, the battery has about 2
minutes of runtime remaining. Immediately
power down your computer, and turn the unit
OFF. When power returns to normal, the unit will
recharge the battery.
Inadequate runtime. The battery is not fully charged. Allow the unit to charge by leaving it plugged in,
and switched on for 10 hours.
The battery is near the end of useful
life.
As a battery ages, the amount of runtime available
will decrease. Batteries also age prematurely if
the unit is placed near excessive heat. If the
battery will not charge, the Back-UPS is no
longer operable.
