keystone adjustment nView D-450 projector

[nViewD-450]

Can anyone help?

I just recieved nView D-450 projector without user manuel. How do I adjust keystone. I was told should be keystone adjustment in the menu, bottom of screen is a bit wider than the top.

Would be nice to read the manuel.

Any help would be much appriciated.

Thanks
