The translation (mind my english)

Version 1.4. excisted 4 disks (two programms.)

The first two disks (disk 1 and 2) is a normal update.

the two others (disk 3 and 4) actualise the tables??

I personally never heart of tables at the Technics instruments I know Yamaha has a database.
So what the last two disks exactly do, i don't know.
Maybe Alex knows.
