Entering ILS frequency in default 747

Is there a way to manually enter an ILS frequency into the FMC without telling it to use a particular STAR? If so, what format does it have to be entered in?

Select the NAV RAD button on the FMC I believe. And I think it’s xxx.yy format for the freq.

I can’t remember if you need to enter the course separately

I had selected the nav rad button, I know where to enter it, but whatever I typed in it wouldn’t accept. Just putting in 108.35 or whatever didn’t work.

Ah, might be the format is identifier/frequency.

If you don’t include the identifier, you still might need the preceding slash.

/xxx.yy

Define identifier.

An ILS has a three or four character identifier code.

None of these are working.

Right I have sussed it, it’s frequency/course, e.g. 109.30/045.
