Operator level no. 3:
To move into the third operator level, first go into the second operator level as described above (Operator
level no. 2). Then scroll up the parameter list to the highest parameter. Then press the UP button and hold
it pressed for at least 10 seconds. The display will show “PA”. Then press the UP and DOWN buttons at the
same time, and hold them both down for at least 4 seconds. This will take you to the parameter list on the
third operat
or level. The parameters there begin with “A1”. You can then use the UP button to move the list
upward, and the DOWN button to scroll downward in this list. When you press the SET button, this will
display the value of a single parameter. If you then press the UP or the DOWN button, then you can increase
or decrease the value of the respective parameter. When you release all the buttons, the new value will be
saved automatically. If you then take no action and press no buttons for more than 60 seconds, the system
will jump back to the first display.
Changing the parameters beginning with the letter “A…” can modify the characteristics of the system. There-
fore, be very careful when modifying these values.
