exited and the console will revert to the Scan mode.

• If the console is "locked" you are prompted to enter the passcode.

3.4.6 PASSCODE PROTECTION
The 910 Series Controller provides a passcode for protection of its configuration. You may
view any portion of the configuration with the console "locked"; however, when you attempt
to initiate an edit session by pressing ▹, you are prompted to enter the passcode. Entering the
passcode is just like entering any other numeric value; see Section 3.4.5 "Changing a Numeric
Parameter."
Once the console is "unlocked," you may edit any configuration parameter. The console will
automatically re-lock after approximately five minutes of keypad inactivity, or until the user
explicitly locks it.
