13.8 Diagnostics
This section provides the procedures for testing the equipment for proper operation.
Three tests are provided: memory I/O test, keyboard test, and test pattern.
13.8.1 Memory I/O test
The memory I/O test checks the memory and signal I/O circuits and displays the pro-
gram numbers. The results for the circuit tests are shown as [OK] or [NG] (No Good).
If [NG] appears, try the test again. If [NG] still appears, contact your dealer for advice.

the factory, are normally displayed as "NG".
Note 2: The test result of [LAN (WIRED)], [CAN], [USB (FRNT)] or [USB (BACK)] is
displayed as "NG" without connection to each port.
