Externally locking the time code
1
Set the POWER switch to ON.
2
Set the TCG switch to F-RUN.
3
Set the DISPLAY switch to TC.
4
Supply the reference time code and reference
video signal which are in a phase relationship that
satisfies the time code standard to the TC IN
connector and GENLOCK IN connector
respectively.
<Note>
When the external lock operation is performed, the
time code is instantly locked to the external time code,
and the same value as the external code value
appears on the counter display.
Do not set the unit to the recording mode during the
few seconds it takes for the sync generator to
stabilize.
User’s bit setting when the time code is externally
locked
When the time code is externally locked, only the time
data is locked to the time data of the external time
code.
This means that the user’s bit can be set separately
for each unit.
The user’s bit can also be locked to the user’s bit of
the external time code. For details, consult your
dealer.
To release the external lock
First stop supplying the external time code, and set
the TCG switch to R-RUN.
When switching the power from the battery to an
external power supply while the time code is
externally locked
In order to ensure the continuity of the time code
generator’s power, connect the external power supply
to the DC IN connector, and then remove the battery
pack. If the battery pack is removed first, no
guarantees can be made for the continuity of the
external locking of the time code.
Gen-locking of the camera unit while the time
code is externally locked
While the time code is externally locked, the camera
unit is gen-locked by the reference video signal which
is supplied to the GEN LOCK IN connector.
<Notes>
O
When the frame rate is set to 24 fps, this unit will
perform the processing in the non-drop frame mode
in order to maintain the continuity of the frames
even when the time code has been set to the drop
frame mode.
Furthermore, when the frame frequency has been
set to 60.00 fps as well, the unit performs the
processing in the non-drop frame mode.
If an external time code generator is used, set it to
the non-drop frame mode.
O
Use the same frame frequency setting for the
reference time code and reference videos signal as
the unit’s setting.
When the frame rate is used at 24 fps, the image
may be disturbed if the frame frequencies differ.

The time code generator of the VTR unit can be
locked to an external generator.

The built-in time code generator is now locked to the
reference time code.
About 10 seconds after locking, the external lock
status will be retained even if the connection of the
externally supplied reference time code is
disconnected. However, the servo lock will be subject
to disturbances if it is connected or disconnected
during recording (REC).
