"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.
