After a password is assigned, the operator must log out to
activate it. Until then, anyone can continue to operate the
instrument without entering the new password.
Only one password can be defined. Before a unique password
is assigned, the system assigns TETAI by default. This allows
access to anyone. After a unique password is assigned, to defeat
the security, the password must be changed back to TETAI.
