<Note>
The system can be configured with multiple units by opening
the <GENLOCK> screen from the SYSTEM SETTING page
and setting the GL PHASE item to the connector using menu
operations.
The phase of the time code can correspond to either the HD-
Y output signals of the MON OUT connector or VBS output
signals of the VIDEO OUT connector. However, the same
value should commonly be set to the GL PHASE for all
cameras. If different values coexist in the system, the
shooting timing may not correspond to each other.

(continued)
In the unit, there is a video signal delay in the camera, which
is required or the process of converting video images taken
with the image-shooting element from the progressive
signals to the interlace signals. Since time is required for
making the 2:3 pull-down from the 24P frame, there is a
video signal delay in the camera. When recording from a
device that can record images without a delay and the unit is
connected in parallel, it is necessary to synchronize the time
code. To set this timing, open the <TC UB> screen from the
VTR MENU page and set it in the TC VIDEO SYNCRO item.
Set by referring to the connection example.
