Figure 4-8 Principle Diagram of Ultrasound System Indicator
Function describes as following:

There are four power status indicators on the IO panel: three are used for indicators of
+12V, +5V and 3.3V output on the DC-DC power board, the other one is used for reserved
indicator.

There are five indicators on the control panel, in which power-on status indicator is below
the power button.

AC power-on status indicator control is output by the power management FPGA on the
power module.

The hardware indicator control is output by CPU.

The status indicator of battery are controlled by the battery management ARM on the
power module which driven by 5VSTB on the main board.

The status indicators of power-on and standby are both generated by the battery
management FPGA in the power module and driven by 5VSTB on the main board.
