3.2.5 DISASSEMBLY of [11] OP BLOCK ASSY/CCD BOARD ASSY
z CAUTIONS
(1) Since the OP BLOCK on this model is more complicated
in structure than previous OP BLOCKS, pay extra
attention to external shocks and vibrations.
(2) During the procedure, be careful in handling the CCD
IMAGE SENSOR, OP LPF and the LENS etc. Pay extra
attention to the soil, dust and scratch on the surface.
If fingerprints are left on the screen, wipe them with clean
chamois leather or a cleaning cloth.
z Disassembly procedure of OP BLOCK ASSEMBLY/CCD
BOARD ASSEMBLY
(1) Remove the HOOD and the OP FRAME ASSEMBLY
first, before disassembling the OP BLOCK ASSEMBLY.
(2) Remove the two screws (1,2) and connector (CN11a),
then remove the CDS BOARD ASSEMBLY.
NOTE11a:
When removing, take out the WIRES prior to other
procedure.
NOTE11b:
When attaching, be careful with the wiring.
(3) Remove the screw (3), and then remove the JOINT PLATE
(4) Remove the two screws (4,5), and then remove the FO-
CUS RING ASSEMBLY.
(5) Remove the two screws (6-8), and then remove the OP
FRAME ASSEMBLY.
NOTE11c:
When attaching, be careful with the GASCKET.
(6) Remove the two screws (9, 10), then remove the CCD
BOARD ASSEMBLY and the HEAT SINK (CCD) at the

When assembling, make sure to interlock the slide
part of the OP BLOCK properly to the axis of the
ZOOM MOTOR.
NOTE11h:
When removing the IRIS MOTOR UNIT, fully pull the
slide part which is interlocked to the axis of the
