Split from Sirec D200 lost password.

I have the same sirec d200 equipment and lost the password

There is no backdoor password.   

You need to contact Siemens support.

Siemens support issues a one day user name/password that accesses the password group.  A one time the recommended action was to use the "password reset" function, which wipes out all policy changes, user names and passwords requiring complete re-configuration of all password functions.

My approach is to use the one day user name/password to get access to the password group and then create a new user with administrative rights.  The new admin user has full admin right and the remaining users and policies are kept intact.  

Password reset does not work for admin level users.  If a locked-out administrator user needs to be unlocked, the only means is to delete it, then recreate it.    

To create the one day user name/password, the support group will need the date as shown in the recorder's status bar (upper right) on which the action will be taken and the six digit internal serial number, printed on the case tag above the CE symbol.   9xxxxx or 8xxxxx format.
