Third operating level
The third operating level can be accessed from the second level by scrolling through the parameter list until the last parameter (P32) is displayed and
pressing the UP button for at least 10 seconds. The message "PA" then appears on the display. Release the button.
Pressing the UP and DOWN keys together for at least four seconds then displays the parameter list for the third operating level (starting with A1).
The parameter values are displayed and adjusted exactly as in the second level.
The list can be rolled up and down with the UP and DOWN buttons.
To display the value for a selected parameter, press the SET button. With the SET button depressed, the value can be adjusted with the UP and
DOWN buttons. When all buttons are released, the new value is saved permanently. If no button is pressed within 60 seconds, the controller reverts
to its normal state.
Note:
If you want to adjust any A parameters, parameter A19 must first be set to "0" (=parameters not locked).
