Prepare for a UPS shutdown. Save your work and turn
off your equipment.
The unit automatically restarts when acceptable power
returns.
Turn the UPS off and plug the UPS into a power outlet
for 24 hours to charge the battery. Turn the UPS on to
test the battery. If the alarm still beeps, see "Replacing
Batteries" on page 7 to replace the battery.
The UPS automatically recharges the battery. The alarm
clears when the battery is recharged.

If the UPS has not recharged the battery after
24 hours, the alarm changes to 3 beeps every 5 seconds
and the battery must be replaced. See "Replacing
Batteries" on page 7 to replace the battery.
