3.1.2.1 Locking the Analyzer
From firmware version 1.0.1 onwards it is possible to lock the analyzer so unauthorized
users cannot change any settings. Go to the SETUP page and in the bottom left
hand corner there is a padlock icon on that is greyed out. Pressing it will bring up
the passcode entry screen where you will need to enter 5491. The padlock icon will
become solid to show it is now activated.
After five minutes, this function will lock the analyzer (you will need to return to the
main screen). To unlock the screen you must enter 5491.
It is possible to deactivate the function before it is triggered or after activation by
simply pressing the solid padlock item in the Settings Menu.
