Use the arrow keys in the left or right key pad to select
the desired switch then assign it with a brief tap on the
center
SET key of the right touch pad.
Notices:
The two FX switches turn a function on "FXI" or off •
"FX " permanently.
All other switches mentioned can have multiple
•
assignments. Pay attention that you do not
UNINTENTIONALLY assign reciprocally confl icting
functions to a single switch. If necessary, note down
the given switch functions.
Application examples:

The control switches, freely programmable in the
"
Control switch " menu, can be incorporated into
switch programming, i. e. assigned to a function instead
of a "normal" switch. At those program locations
where switches can be assigned you always have the
opportunity to assign one of the control switches, C1...
C4, instead of a physical switch by selecting one of
these out of the list of "external switches".
