(I'm not sure why you keep insisting following a path that there is no evidence of existing. I'm also not sure why I'm the only person who appeared to do any research.)

I'm just asking questions out of curiosity mostly and mainly expected that my comments and questions were for the OP. I did one try to search for the manual and came up empty. I wasn't expecting you to fill me in, but I appreciate that you did.
