No. Key Test item Test function and judgment criteria
31 G4 MIDI check Connect the [MIDI IN] jack and [MIDI OUT] jack with the MIDI cable and execute the test.
For the OK test result, the sine wave of C4 sounds (for 1 second).
For NG, the sine wave of C2 sounds (continuously until any key is pressed).
41 G#4 Master ROM check 2 To check the ROM checksum connected to the CPU bus (Full address)
For the OK test result, the sine wave of C4 sounds (for 1 second).
For NG, the sine wave of C2 sounds (continuously until any key is pressed).
It takes 12 seconds before checking is completed.
42 A4 Slave ROM check 2 To check the ROM checksum connected to the CPU bus (Full address)
For the OK test result, the sine wave of C4 sounds (for 1 second).
For NG, the sine wave of C2 sounds (continuously until any key is pressed).
It takes 12 seconds before checking is completed.
43 A#4 RAM check 2 To check RAM connected to the CPU bus (Full address)
For the OK test result, the sine wave of C4 sounds (for 1 second).
For NG, the sine wave of C2 sounds (continuously until any key is pressed).
It takes 2 seconds before checking is completed.
As execution of this test causes the entire data on RAM to be rewritten, it is necessary to ex-
ecute initialization after this test.
45 B4 Flash ROM check 2 To check erase, write, read functions for all banks of Flash ROM
* Note that execution of this test causes all data in Flash ROM to be erased.
(a) Erase function check
Perform the erasing procedure to the entire Flash ROM and check if it is successful.
(b) Write function check
To check the full address checksum of Flash ROM
* Be careful not to turn off the power during the write function check.
(c) Final erasure
To erase the data written during (b) Write function check.
For the OK test result, the sine wave of C4 sounds (for 1 second).
For NG, the sine wave of C2 sounds (continuously until any key is pressed).
It takes 27 seconds before checking is completed.
47 C5 Factory Set To initialize all the backup areas to restore factory default. (RAM and Flash)
* Note that all the data will be erased.
For the OK result, the sine wave of C4 sounds (for 1 second).
For NG, the sine wave of C2 sounds (continuously until any key is pressed).
It takes 7 seconds before the execution is completed.
* After executing this factory setting, be sure to execute test No. 48 “Test Exit”. Initialization of
the memory is actually executed when the program is restarted (REBOOT). The REC and
PLAY LEDs will begin to fl ash after the restart. Do not turn off the power until LED fl ashing
comes to an end.
It takes 20 seconds before LED fl ashing comes to an end.
48 C7
Test Mode Exit
To end the test program and reset to the normal mode (for restarting).
