User manual for an 1988 "Hitachi" CMT 2138 tv

[Telecolor 3007]

I own and sept. 1988 made "Hitachi" CMT 2138 color tv set. The tv belonged to my father, then to my grandmother and when my father bought an L.C.D. tv it gave a bigger one to my grandmother; I took it because I didn't want the set to be dumped/or to be salled in a buy back sistem.
The big problem is that I don't have a user manual for it so I can't really figure how to memorize the station. I manage too look for stations, memorize some but only after a hard automatic search. B.t.w., it is possible that the set was built only with R.F. input and no R.C.A. or B.N.C. connectors?
I don't have any pics of it because for the moment I don't have a digital photo camera.
