C3
ROM version check
To check the Main ROM version using C0-A2 keys.
To check the Wave ROM version using C3-A5 keys.
Press keys in the speci
fi
ed range and
fi
nd the key where the sine wave sounds. Check the
version by the scale of that key. (See Fig. 3)
Press keys C0-A0 to check the integer of the Main ROM version.
Press keys C1-A1 to check the
fi
rst decimal place of the Main ROM version.
Press keys C2-A2 to check the second decimal place of the Main ROM version.
Press keys C3-A3 to check the integer of the Wave ROM version.
Press keys C4-A4 to check the
fi
rst decimal place of the Wave ROM version.
Press keys C5-A5 to check the second decimal place of the Wave ROM version.
When the number corresponding to the pressed key agrees with the current version, an
OK (sine wave of C4) sound is generated and when disagrees, an NG (sine wave of C2)
sound is generated.
For the Key-to-number correspondence, refer to Fig. 3.
Example) When the current version is Ver.1.00(Main ROM)
When the C#0 key is pressed. the sine wave of C4 sounds, indicating 1 for the integer.
When the C1 key is pressed, the sine wave of C4 sounds, indicating 0 for the
fi
rst
decimal place.
When the C2 key is pressed, the sine wave of C4 sounds, indicating 1 for the second
decimal place.
In this way, the version 1.00 is con
fi
rmed.
(The sine wave of C2 sounds when any key other than C#0, C1 and C2 is pressed.)
2
C#3 ROM check 1
To check the ROM checksum connected to the CPU bus (Simpli
fi
ed 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).
3
D3
RAM check 1
To check the connection condition of RAM connected to the CPU bus (Simpli
fi
ed 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).
4
D#3 Flash ROM check 1
To check erase, write, read functions for speci
fi
c bank of Flash ROM (Simpli
fi
ed 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).
5
E3
Wave ROM check 1
To check the ROM checksum connected to the bus of tone generator LSI (Simpli
fi
ed 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).
6
F3
Effect RAM check 1
To check the connection of Effect RAM connected to the bus of tone generator LSI
(Simpli
fi
ed 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).
