LED and audible alarm troubleshooting 
This UPS is designed for durable, automatic operation and also alerts you whenever potential operating 
problems might occur. Usually the alarms shown on the control panel do not mean that the output power is 
affected. Instead, they are preventive alarms intended to alert you of a possible condition. 
The following table describes typical alarms and conditions. If an alarm appears with a service code, contact 
HP technical support ("HP contact information" on page 107).  
To check the Event Log for a list of active alarms: 
1.  Press any button on the front panel display to activate the menu options. 
2.  Press the down arrow button until EVENT LOG displays. 
3.  Press the right arrow button to display the list of alarms and conditions.
