CyberPower’s CP900AVR has an uncomplicated-to-use interface with just two buttons (electrical power on/off and mute) and 4 indicator lights (exhibiting once the unit is turned on, once the battery backup kicks in, when AVR is activated, and when there’s an influence overload) to the entrance in the device.
