Chapter 4 Adjustments and settings for recording
34
1
Set the POWER switch to ON.
2
Set the TCG switch to F-RUN.
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.
3
Set the DISPLAY switch to TC.
4-5-3 Setting the time code
1
Set the DISPLAY switch to TC.
2
Set the TCG switch to SET.
5
Select the TCG switch position.
Select “F-RUN” to advance the time code in the free-run
mode or select “R-RUN” to advance it in the rec-run
mode.
4
Set the time code using the SHIFT button, UP (+) button
and DOWN (–) button.
3
Open the <TC UB> screen from the VTR MENU page by
performing menu operations, and select DF or NDF as
the TC MODE item setting. To advance the time code in
the drop frame mode, select DF; to advance it in the non-
drop frame mode, select NDF.
Time code when the battery is replaced
The backup function works even when the battery is replaced,
and the time code generator continues to operate for a
prolonged duration (approx. 1 year).
<Note>
If the POWER switch is turned on, then off, and then on
again, the free-run time code backup accuracy is
approximately ±2 frames.
4-5-4 Externally locking the time code
The unit’s internal time code generator can be locked to an
external generator. In addition, the time code generator of an
external VTR can be locked to the unit’s internal generator.
Example of connections for external locking
As the figure shows, connect both the reference video signal
and reference time code.
Example 1:

Example 2:
When connecting a multiple number of units and
using one of them as the reference unit
<Note>
When configuring a system using a multiple number of units,
perform menu operations to open the <GENLOCK> screen
from the SYSTEM SETTING page, and select DOWNCON as
the GL PHASE item setting. This enables the phases of the
down-converted output from the VIDEO OUT connector and
the time code to be brought into alignment.
Operating procedure for external locking
Follow the steps below for external locking.
<Note>
In place of the HD Y reference signal, NTSC composite video
signals can be input as the reference video signal.
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.
