The parameter programming procedure is accessed by pressing the 3UJ button for 3 seconds. The various levels of parameters
are accessed by entering different passwords.
The parameters that can be modified from the user interface are divided into 3 levels, so as to guarantee maximum security and
user friendliness for less expert users. The display of the parameters depends on the level of password entered; the highest level
password, level 3, allows both the parameters and the passwords to be modified.
The parameters are grouped into screens according to function and the priority. The screens belonging to levels higher than that
accessed by the password entered are not displayed.
