Page 15 - Press the EXECUTE button to begin the test. - The test result (OK or NG) is displayed within a few seconds. If the test result is NG, not only the respective IC, but also a break or short circuit in the ADDRESS/DATA BUS as well as in any of the strobe signal lines may be the cause of the failure.
Page 16 test results in OK or NG are counted and displayed on the LCD. To interrupt the test, press the STOP button. - Even when the Floppy Disk Drive is functioning properly, the test can result in NG. If this happens frequently, clean the magnetic heads of the Floppy Disk Drive with a cleaning disk.
Page 17 CROSSTALK: An H pattern is shown. LCD crosstalk can be evaluated. To exit this test, press the EXIT button. SAMPLE: Several display patterns shown during normal use are shown. The display can be held by pressing the DISPLAY HOLD button. CONTRAST: The test pattern is shown.
Page 18 terminals. - When a keyboard key is pressed, the transmitted and received data are compared and the MIDI terminal operation is indicated as being OK or NG. - If NG is shown, check both the IN and OUT terminals, as well as the circuit.

(No touch, fixed stereo center) By generating a sound frequency outside the normal keyboard zone, you can confirm whether or not there is an abnormality in the sound output frequency zone.
Page 20 9.2. Notes on replacing FLASH ROMs The replacement parts contain a FLASH ROM with a available memory and the PROGRAM DISKs which include the program to be written into the PROGRAM ROM. After replacing the PROGRAM ROM, always write the program into it from the PROGRAM DISKs includedin the replacement parts.
