HOW TO IDENTIFY MODELS
How to recognize from the appearance of the model concerned is written below.
Please distinguish from several contents currently printed on the rating label of the rear panel or “SPECIALIZER” logo mark of the
front panel.
(blank) : HR-XVC1U or HR-XVC1UC
/M : HR-XVC1U/M or HR-XVC1UC/M
"SPECIALIZER" logo mark
3D STEREO: HR-XVC1U or HR-XVC1UC
N-2-2: HR-XVC1U/M or HR-XVC1UC/M
RATING LABEL
Circuit board assembly and unit compatibility between HR-XVC1U (or HR-XVC1UC) and HR-XVC1U/M (or HR-XVC1UC/M)
Since the same parts are used for the VCR mechanism section and power supply circuit board assembly for the HR-XVC1U (or HRXVC1UC) and HR-XVC1U/M (or HR-XVC1UC/M), they are interchangeable. However, there is no compatibility for the VCR circuit board,
DVD circuit board, and DVD drive unit.
1. The difference in the VCR circuit board is the connection cable that connects to the DVD circuit board. It is not possible to connect an
old board to a new board.
2. The difference in the DVD circuit board is the substantial difference in external dimensions. There is also no compatibility in terms of
specifications.
<Reference>
When an old VCR circuit board is forcibly connected to a new DVD circuit board, there is a terminal that changes HR-XVC1U (or HRXVC1UC): 3.3V⇒HR-XVC1U/M (or HR-XVC1UC/M): 9V and the DVD circuit board will be damaged.
3. It is possible to install the DVD drive unit in the chassis. However, since there is no compatibility between the DVD circuit board and the
connection cable, it is not possible to connect old and new together.
<Reference>
If the entire set of revised parts is exchanged at once (DVD drive unit, VCR circuit board, DVD circuit board (with attachment angle)),
the specifications for Spatializer will change from 3D Stereo ⇔ N-2-2. This type of process will cause non-compliance with certified
specifications, so do not interchange old and new type parts.
