Does Anyone Know How To Access The NWZ-S765 Test Menu?

[Forze]

Hi guys'n girls:

last year i bought a Sony S-series walkman (euro model) & accessed the test menu to remove the limit. Unfortunately i lost the walkman last weekend & I bought a new NWZ-S765 16gb (euro model again).

I can't find any solutions to access the menu & to remove the limiter.

Any possible tips n tricks for this one?

Thanks in advance
