Teledyne 3020T operating instructions Only one password can be defined, Entering the Password

4 Operation Model 3020T

Once a unique password is assigned and activated, the operator MUST enter the UNIQUE password to gain access to any of the set-up functions (except to enter the password). However, the instrument will continue to analyze sample gas and report on alarm conditions without entering the password.

•Only one password can be defined.

•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.

•To defeat the security after a unique password is activated, the password must be changed back to TETAI.

NOTE: If you use password security, it is advisable to keep a copy of the password in a separate, safe location.

4.4.1 Entering the 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, issuing the ENTER command will enter the default TETAI pass-

word for you.

Scroll to PWD, and ENTER to select the password function. Either the TETAI default password or AAAAA place-holder password for an existing password will appear on screen depending on whether or not a password has been previously installed.

The last ENTER enters the password.

If the password is accepted, the screen will indicate that the password restrictions have been removed and you have clearance to proceed.
