Ancient regency scanner help?

[edwftx]

I found my Papa's old regency informant scanner and it works! It is an old informant model inf 5.
My question is there a way to lock out a single agency. It has all the old conventional "action bands" pre programmed SP LP FD MD but it stops on some local bussiness freq and stops scanning on some interference I do not want to lock out the whole SP LP and such just the stuff and interference on an individual frequency.

I used to have one of those and it was an interesting receiver. It was aimed at people who didn't know, or didn't want to program in frequencies. You can only scan the preset bands and there is not way, to my memory, to lock out anything other than an entire band. It wasn't much good because of that and I remember getting rid of it pretty quick. I think it was only single conversion as well and had terrible intermod.
