Teledyne 4040 - Methane / Nonmethane analyzer - Manual (Page 55)

Operation
Teledyne Analytical Instruments 55
Note however, that the instrument can still be used for analysis
without entering the password. To defeat security the password must be
entered.
Note: If you use password security, it is strongly advised to
keep a copy of the password in a separate, safe
location. If the password is lost and security is
enabled, the analyzer must be cold-booted. Cold
booting invalidates parameters necessary for correct
operation so they must be re-entered.
ENTERING A PASSWORD
To install a new password or change a previously installed password,
you must key in and ENTER the old password first. If the default
password is in effect it will be displayed as the default gausses for each
letter, pressing for each letter of the password will enter the
default password for you.
