Check the Main Board

The main board is the control center of the generator where an Arm CPU is
located. Please refer to chapter 4 if you wish to separate it from the channel
board.

Voltage Checking

Test the voltage test points on the main board and compare to the table below.
If each tested voltage value is within the corresponding specified range, then
the main board is working normally. If the voltages are out of the specified
range, please return it to the factory for repair or contact SIGLENT.

ARM CPU System Checking

Observe the LED lights on the main board, which indicate the working state of
the ARM CPU system. If the LED lights blink at a regular rate, then the
corresponding codes have been loaded successfully and the chip is in an
operating state. Otherwise, there may be a problem.
