Password
Function: Protects entry to the system at various levels

different levels.
Default: Disabled
Password protection restricts user entry to different levels within the recorder. Passwords
will be disabled on start up and the recorder will default to a predetermined password,
which is displayed. ’Eng’, is the highest level of access to all screens.
The default password is ”PASS”. From here the Engineer can allocate other users and
their levels of access to screens within the recorder. Each user creates their own password
when they initially log on. Each user, including ‘Eng’ is responsible for remembering
their own password, ‘Eng’ level cannot access the passwords for other users.
NB. If the user does forget the password the user must be deleted from the recorder
and start again. If ‘Eng’ user forgets their password and no access is available, contact us
at SIEMENS and an override password can be issued.
This password system allows traceability by the users name, not the password.
