I just received my new Infinium today and started out air testing it to begin getting familar with it. When I try the iron check feature, the machine shuts down. If I turn the Disc control back to 9 it fires back up as evidenced by the machine going through the battery check beeps. Has anyone got any ideas as what I might be doing wrong,etc.. The machine other than this seems to work fine as near as I can tell. Thanks for any help, Mike
