The UPS has a four-button dot matrix LCD with dual color backlight. Standard back-light is
used to light up the display with white text and a blue background. When the UPS has a critical
alarm, the backlight changes the text to dark amber and the background to amber.
Besides the LCD, the UPS has four colorized LEDs to provide more convenient information.
