kovacslajcsi 0 Posted March 5, 2014 Hi, I have a Techson DVR, but the admin password was lost. I can't find any usable manual, or help to reset the password for the unit. The default 123456 does not work. To take out the CR2032 battery does not help, only the time is lost. May be the unit is sold under separate brands over the world. The main PCB is marked as a DVR408 type. How can i restore the admin password, or restore the unit back to factory state? Thanks! Share this post Link to post Share on other sites
