3. Settings and Adjustments: Setting Time Data
timecode generator with the external
timecode. Once about ten seconds have
elapsed after the timecode locks, the external
lock state is maintained even if the external
timecode source is disconnected.
To release the external synchronization, first
stop the external timecode input, then set the
F-RUN/SET/R-RUN switch to R-RUN.
[Notes]
ˎ When you finish the above procedure, the internal
ˎ
timecode is immediately synchronized with the external
timecode and the time data display will show the value of
the external timecode. However, wait for a few seconds
until the sync generator stabilizes before recording.
ˎ If the frequency of the reference video signal is not the ˎ
same as the system frequency of the camcorder, the
camcorder cannot be correctly genlocked. If this occurs,
the timecode will not acquire successful lock with the
external timecode.
User bit settings during synchronization
When the timecode is synchronized to an external
signal, only the time data is synchronized with the
external timecode value.
Note on changing the power supply from the
battery pack to an external power supply during
external synchronization
To maintain a continuous power supply, connect
the external power supply to the DC IN connector
before removing the battery pack. You may lose
timecode external synchronization if you remove
the battery pack first.
Camcorder synchronization during external
synchronization
During external synchronization, the camcorder is
genlocked to the reference video signal input from
the GENLOCK IN connector.
