Checking user setting contents The contactless fader is mounted in the cross fader part of this product. This has several times of durability comparing with conventional types.

17、As assembly of the fader part is required high precision, service parts are provided only as an assembly (Part name is CROSS FADER ASSY (DXA2257). After replacing the part, make sure to conduct CROSS FADER CALIBRATION (CFDR SET) in the test mode. If this calibration is not conducted, normal start is

18、 not possible. If MAIN ASSY is replaced, make sure to conduct CROSS FADER CALIBRATION (CFDR SET) after the replacement. About the replacing CROSS FADER ASSY Display part of this product employs OLED. Exchange at the time of OLED failure, replace using OLED ASSY (DEA1065). Matrix OEL is stick to Hold
