The respective functions are disabled when the protection level is activated. No password is
required for activation. A password must be entered to deactivate the protection level. The
password for the first level is 123456. This protection level can be used to lock-out internal
adjustments.
The command triggers an event and therefore has no *RST value and no query form.
