How to reset NEC Baseline Pro SIP ADMIN password

[L.Fugi]

Hello all,

I have a NEC Baseline pro Sip and the default password has been changed, is it possible to return the configuration to the factory default without the password?
I've tried pressing menu and zero but the keyboard doesn't respond...
After boot it's 'Auto Configure loading...' and then 'Error while configuring...' - No keys work after that.

Thanks!
