My CyberPower unit is beeping. Why?
CyberPower units have a feature called “Sensitive to on line voltage”. This detects quick changes that occur in the AC voltage. These changes are within the safe operating range of the unit. When these occur, the UPS switches to battery power to keep the voltage constant. This feature can become disruptive with the unit beeping frequently. If it does, the sensitivity feature will need to be turned off. Turning off the Sensitivity feature. Click on the battery icon near the time display in the lower right corner of the screen. Click on Setup. The first line in the setup screen is labeled “Sensitive to variation online voltage.” Uncheck the box to the left of this line. Click the OK button. Minimize the display by clicking on the green minimize bar under the power button. Shutdown the computer. Turn the CyberPower unit off. Wait 15 seconds. Turn the unit back on. The unit will beep three times during a self-test.
