Cannot set the clock on Fanuc oi-MF?

[wendaiyu 0]

Hi, folks, how’s going?

 

We have one Fanuc oi-MF machining center.  I tried to set the clock, because it’s one hour behind, but no luck.

 

Those are what I did:

1, set machine in “MDI” mode;

2, enabled PARAMETER WRITE function (=1);

3, but when I pressed INPUT to set up TIME, always showed “WRITE PROTECT”.

 

Could somebody gave me a help?

 

Thanks a lot.
