Hello,

To correct turn off UPS by pressing and holding the power on/off button, brain dead the unit, and restart. 

To brain dead

1) Turn off and unplug UPS from wall
2) Disconnect Battery
3) You may hear an audible "click" from the UPS.
4) Reconnect battery, plug unit back in the wall, and turn UPS back on

If issue persist contact local support for assistance.
