If the alarm is still active and you would like to hear the alarm again, press the bottom
key again. The display will show “Un” for “unsilence,” and the unit will begin sounding
the Morse Code for the alarm.
6B. Reacting to Alarms
The UPS display switches between the normal display and an alarm message. Go to the
Alarm Table on the next few pages and find your alarm message in the left column.
Follow the instructions for that alarm. The UPS also sounds the alarm letter code in
Morse Code; if you are not near the UPS, you can use the Morse code and the table on
the next few pages to identify the alarm.
Example: If the display shows “OL” as shown, read the information next to “OL” in the
Alarm Table. The table shows that this is an overload alarm, and you must
disconnect some of the equipment plugged into your UPS.

High Battery. Battery voltage is
high, which could mean there
are battery or charger problems.
When the UPS sounds this
alarm, it cannot charge the bat-
teries.
Fan Malfunction. The fan is not
operating. If the problem contin-
ues, the UPS will shut down.
Calibration Lost. This can hap-
pen when you replace the batter-
ies if the UPS is off and you
wait too long to install the new
batteries. The alarm means the
UPS has lost any changes you
have made to parameters via
two-way communication; it may
also mean the UPS has lost
internal factory settings.
