"Raise" and "Lower" keys:
These keys are used for any operation that
requires a numerical parameter to be raised or
lowered. ••The speed of change is proportional to
the time the key is pressed. •• The operation is
not cyclic: once the maximum (minimum) limit is
reached, there will be no further increase
(decrease) of the value, even if the key remains
pressed.
The keys can be configured to perform reset,
hold, display of the peak value, etc. as
determined by the 't.U.' and 't.d.' parameters on
the 'In' menu.
