[Telequipment Type D54]

Hi,
I have acquired this old oscope,
I don't know how to use one as I'm newbie
in electronics, but very much wanted to learn.
I am in need of a user/repair manual so
I'd know if this oscope is functional.
Some buttons and dials on this thing is
functional but I don't know if the whole thing function
hence the need for  user manual, perhaps there's a
built in test or something.

thanks.
