I've been given this old set which I wish to use with a couple of modulators but am having trouble tuning/storing anything.
I have found pressing "F" four times gets me into a tuning mode and I can tune with the vol + or - buttons very very slowly so I guess that is fine tuning. Picture and sound is good but I can't find anyway to store it to a preset. I have the remote (I assume it is the correct one).

Any help appreciated.

Have you tried here?

Yes, sadly it does not help.
