4) Perform waveform inspection
Inspection: Inspect each board separately.
!
Place the logic main boards on the inspection table so that they do not touch each other.
❈
Install the TEST PROM and check the SW2001 setting.
@
Connect CN803 of the logic main board to the linear power supply (or SMPS).
(Use a 10-pin connector cable.)
❈
Make sure to connect when the linear power supply (or SMPS) turned off.
#
Turn on the linear power supply and apply 5V and 3.3V power to the logic main board.
Then, check whether the LD2001 LED indicator, located at the top left of the board, blinks about
once per second.
If the LED indicator blinks too fast or is not lit up, it indicates tat the logic board is not operating
normally.

Measure each waveform on the board and compare to the waveforms on Attachment 1.

After completing the inspection, set the SW2001 switch to the external pattern.
