The M400E provides password protection of the calibration and setup functions to prevent unauthorized
adjustments. When the passwords have been enabled in the PASS menu item, the system will prompt the user
for a password anytime a password-protected function is requested.
There are three levels of password protection, which correspond to operator, maintenance and configuration
functions. Each level allows access to all of the functions in the previous level.
