Note:
1) The CCD image sensor, 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.

Cautions during disassembly and reassembly:
Take care with the orientation of crystal filter when assembling it: Incorrect orientation of the
crystal filter could cause a fault.
