Action
Plug the UPS into a wall outlet for 24 hours to charge the

If the Battery Service indicator is still on, see "UPS
Maintenance" on page 19 to replace the battery.
Change the alarm setting. See "Configuration Mode" on
page 15.
Correct the input voltage, if possible. The UPS continues to
operate on battery until the battery is completely discharged.
If the condition persists, the input voltage in your area may
differ from the UPS nominal. Change the UPS input voltage to
match your local voltage (see "Configuration Mode" on
page 15).
