Well after scouring the googles I have found the manual for an rca cpr 250 which is similar so I’ll try that. I can’t find anything on the cmr 300 sadly.

The manual had nothing to say about the cameras internals, only it’s features. I’ll try to get the gears reset tomorrow

Okay idk if this pic will load but
I think I may have figured it out but I’m still stuck. The red line bit cane loose from the blue wheel but it cannot reconnect unless the green bar slides back but it absolutely won’t budge. I see no obstruction but I’m going to take it apart to see.
