LCD Monitor and Menu keys

The user-friendly and menu-driven 320 x 240 dot graphic LCD monitor displays real time data and at
the same time stores 512 historical records that can retrieve for reference and diagnosis.
The user can perform commands or easily browse through the input, output, load and battery param-
eters. For quick reference, the UPS status and any warnings are always highlighted without the need
of navigating through the menu. The versions of converter firmware, inverter firmware and internal
monitor firmware can also be displayed on the LCD.
Menu keys F1 to F4 are used to navigate within the graphic LCD monitor windows.
