Hi sorry if this is in the wrong part of the forum but was not sure where to place it. I need help before I go bold How do I factory reset a Sumluxy SLDVR4-4600 H.264 as I do not know the password it keeps asking for every time I try to connect. when I right click on the screen the window opens with the admin selected but when I leave the password part blank it says password error. So the only way I thought was to do a factory reset but I cannot find out how to do it I have already tried taking the coms battery out for half an hour but that just lost the time the errors still there HELP'
