Dear All,

Could somebody please tell me how can I set the VOR radios manually. I tried it in RAD/NAV page, but it says invalid entry. The VOR1 and VOR2 frequencies are set automatically, but how can I set them manually. In case of the 767 there is an option to set MAN or AUTO below the frquency selector knob, but I can not find such an option in the B777.

Thank you in advance,

Peter
