CyberPower’s CP900AVR has a straightforward-to-use interface with just two buttons (electric power on/off and mute) and 4 indicator lights (showing once the device is turned on, when the battery backup kicks in, when AVR is activated, and when there’s a power overload) within the entrance from the unit.
