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