3.5 Security access
There are three levels of security access allowing write access to setpoints, lockout reset,
and firmware download. When there are no pop-ups present, a sustained press on the
ESC
key clears the security passcode. When operations are performed that require a higher
level of security, a passcode entry dialog box automatically opens (for example, in entering
factory page at read only security access).

The encrypted key information appears only when the current security access level is 0.
