Third control level (all parameters):
Setting of control parameters
Access to the third control level is granted when selecting parameter PA on the second control
level. Parameter PA is to be set at '
-19 '. Then the key UP and DOWN have to be simultaneously
pressed for approx. 4 seconds which will give access to the third control level, beginning with
parameter P0. With the keys UP and DOWN you can scroll the list in both directions. Pressing the
SET key will give you the value of the respective parameter. By pressing the UP or DOWN key at
the same time the value can be adjusted.
Return to the initial position takes place automatically, if no key is pressed for 60 seconds.
