Canon E250 8mm Video Camcorder

I got this fine camera and I simply found that the IR focusing is turned to full on (maximum distance), the eject is working erratically, if at all, the recording function is unknown since play is just different type of distorded noise.
On the other hand, it has a lovely subminiature picture tube ELY06V572B which google has no clue about. It is about 2 inches long and has coil deflection and a sharp picture. I would like more info about the battery detect switches there.
