USB and SD Card Slot Ports
To verify proper operation of any rear USB ports or SD Card port:
— Connect a known good USB flash memory or SD memory card.
— Wait 15 seconds for the analyzer to verify the device connection, and then
check the operation of the USB flash memory or SD memory card by
performing the recall function Save/Recall.
— If the device performs correctly, the USB or SD Card port is functioning
properly.
— If the device does not perform correctly, the System board is faulty. Refer to
