NL2000SY language change

Hello all.
I recently bought used NL2000SY lathe, MSX-850 3, Mitsubishi controls.
Unfortunately it is in Italian and I can not find where to switch to English.
Local dealer (just a small company who sells Mori Seiki here) checked this lathe and told that he has never seen such model and does not know how to change language.
Does someone know how to change language? I already tried all tutorials I found from the web, but lathe is still in Italian.

Finally I figured it out. Maybe it will be useful for someone else. Need to change parameters 1471 and 1472. Parameters and available languages are:
0 English
1 Japanese
2 German
3 French
4 Italian
5 Spanish
6 Dutch
7 Chinese (Traditional)
8 Swedish
9 Portuguese
10 Danish
11 Norwegian
12 Finnish
13 Czech
14 Slovenian
15 Chinese (Simplified)
16 Hungarian
17 Korean
18 Turkish
