Description of Self Test Items C-19
If the flicking works well, the program passes, and then exits the test.If the flicking fails to work,
click “Touch Screen is Bad”.
◼ Analysis to test failure
The touch screen does not work if the test result is FAIL.
◼ Suggestion to failure test
Confirm the drive of the touch screen is installed properly.
Then confirm whether connecting material between the touch screen and main unit is fixed well.
It is recommended to replace touch screen.
C.1.41 Z1301 Mini CW Board ID Test
◼ Top test item
DSP FPGA and TRA FPGA communication self test (control interface)
◼ Test content
The program reads the signal in the place to decide whether mini CW board is in the place. Then,
read CW board’s ID. SPI interface communication between TRA board and mini CW board works
well if it appears non-0 and non-F.
◼ Analysis to test failure
The drive goes wrong if the test result appears Error.
Mini CW board is not in the place if the information “Mini CW board is not in the place” appears or
the circuit is not in the place.
The interconnection between mini CW board and TRA board goes wrong if the test fails.
◼ Suggestion to failure test
Restart the device to perform the self test if the test result appears Error. It is necessary to restore
the device (OS+doppler) if Error re-appears.
It is recommended to replace mini CW board if the test result is FAIL.
