Relative mode (RELATIVE button lit): There is no
absolute correspondence between the position of
the ring (or knob) and the adjustment value. The
position of the ring when Relative mode is selected
will be the reference position for the subsequent
adjustment. The center position does not always
represent the median value for the adjustment.
In the following cases, Relative mode is
automatically selected.
– When an auto setup operation is completed
– When a scene file is retrieved
– When the IRIS/MB ACTIVE button goes
dark
Absolute mode (RELATIVE button not lit): The
position of the ring (or knob) absolutely
corresponds to the adjustment value and the center
position always represents the median value of the
adjustment.

Adjusting on the MSU-700A/750 and RCP-700/701/
741 is always performed in Relative mode.
