If fingerprints are present on the surface they should be wiped away using either a silicon paper, clean chamois or the cleaning cloth. (2) The CCD IMAGE SENSOR may have been shipped with a protective sheet attached to the transmitting glass. When replacing the CCD IMAGE SENSOR, do not peel off this sheet from the new part until immediately before it is mounted in the OP BLOCK ASSEMBLY. (3) The orientation of the OP LPF is an important factor for installation. If there is some marking on the OP LPF, be sure to note it down before removing and to reassemble it very carefully as it was referring to the marking. Disassembly of CCD BOARD ASSEMBLY and CCD BASE ASSEMBLY (1) Unsolder the CCD BOARD ASSEMBLY by the 14 points (SD16a) and then remove it. (2) Remove the two screws (1, 2) and remove the CCD BASE ASSEMBLY. Assembly of CCD BASE ASSEMBLY and CCD BOARD ASSEMBLY (1) Set the OP LPF to the OP BLOCK ASSEMBLY so that the OP side touches the OP BLOCK ASSEMBLY. NOTE 16a: Pay careful attention to the orientation of the OP LPF. Set the SHEET to the OP LPF not to come off the right position. Attach the SPACER to the OP BLOCK ASSEMBLY. Fasten them together with the two screws (1, 2). Set the CCD BOARD ASSEMBLY in the CCD BASE ASSEMBLY, and then solder it by the 14 points (SD16a). (2) (3) (4) (5) Replacement of service repair parts The service repair parts for the OP BLOCK ASSEMBLY are as listed below. Before replacement of these parts, remove the BRACKET (OP BLOCK ASSEMBLY) as required. Take special care not to disconnect any of the FPC wires or cause any damage due to soldering (excessive heating). (1) FOCUS MOTOR (2) ZOOM MOTOR (3) IRIS MOTOR UNIT NOTE 16b: When replacing the FOCUS MOTOR or the ZOOM MOTOR, solder the FPC at a space of about 1 mm above the terminal pin. NOTE 16c: The IRIS MOTOR UNIT includes the FPC ASSEMBLY and two sensors.
