Disassembly and Reassembly > Disassembly
(31) Lens Frame and Lens Unit
1) Remove the two screws [F] and then remove the lens frame (a).
2) Disconnect the flat cable.
3) Remove the two screws [H], and then remove the lens unit (b), sensor frame (d), cushion (e) and
crystal filter (f).
Note:
1) The lens unit and crystal filter are precision components: Take great care when handling them.
Adherence of any dust, foreign object, fingerprint, etc. to them, or any scratches or impact, could
cause a fault.
2) Never use metal tweezers to handle the crystal filter: Doing so could damage it.
