Contents Included and Reference Materials
Model DZ-MV380A/MV380A(K) is basically the
same as the DZ-MV350A/MV350A(K): The
CCD (image sensor) and lens have been
changed.
This service manual therefore includes only
differences from the DZ-MV350A/MV350A(K)
manual.
When servicing the DZ-MV380A/MV380A(K),
use the DZ-MV350A/MV350A(K) service
manual (no. 7301E) along with this manual.
Refer to "2.1.1 Contents Included in Manual
and Reference Materials" on page 2-1 for
