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