Vintage camcorder GAF ST/802 Super 8 Movie Camera "Partly Tested"

Description

I put in batteries as you can see the green light in a picture is on.  You can hear it running when you push the button on the handle.  The tele/wide buttons made the lens go in and out so I'm assuming that works.  There was a film in it as shown but I don't want to include that in this because it was there when I picked it up and I don't know what is on it so its going in the trash.
It takes 4 AA batteries in the handle.  I took them back out so not included.  I believe I read on google that it also takes a button battery that goes in the camera also inside the handle where the silver screw thing is.(picture 5). I have a picture of me pressing a button which opens the film storage area.  There is much information inside it. (picture of).  It also says in there in order to conserve c & s battery the EE system will operate only when film cartridge is inserted.  I don't know what the EE system is so?  I also removed the eye rubber thing because it was falling a part and leaving black stuff all over hands.
