Riello Master Plus – What does the Display show?

The Riello Master Plus display shares some similarities to the MST display, with some noticeable differences. The control panel at the front of the UPS allows you to monitor and control the UPS and battery parameters. The control panel includes both a liquid crystal display and 6 status LEDS (three on each side of the screen), along with 8 function keys. The bottom of the LCD screen shows what each function key does based on whichever menu you are in.
