1) Drop frame mode
In order to compensate for differences between time
code values from the time code generator and the actual
time that occurs when the field frequency of this unit is
59.94 Hz, the drop frame mode causes the time code
generator to omit the first two frames (frame 00 and 01)
in each minute except the tenth.
2) Non-drop frame mode
In this mode, drop frame mode processing is not
performed.  Since there is no frame cutting, a
discrepancy of about 86 seconds occurs each day (in the
case of a field frequency of 59.94 Hz).

4-3-3 Setting the Time Code
Generator (TCG SOURCE/MODE)
There are two ways to record time codes on the VTR.
One way is to record the output of the VTR’s internal
time code generator.  The other is to directly record
time codes that are input from an external time code
generator.
The output from the internal time code generator can
either be set to a specified initial value, or
synchronized with an external time code generator.
The internal time code generator time code settings are
made with the [F6] (TCG SOURCE)/[F7]  (TCG
MODE) buttons. Menu selections and settings are
shown below.
Note
Regenerated signals are selected using the 608.TCG/
UBG REGENE MODE setting in the VTR SETUP
menu.
To check the running of the internal time code
generator
Press the INPUT CHECK button.
4-3-4 Selecting the Time Code
Running Mode (RUN MODE)
Press the [F8] (RUN MODE) button to select the time
code running mode.
free:  The time code advances when the power is on
regardless of the VTR’s operation mode.
rec:  The time code advances only during recording.
4-3-5 Selecting the Drop Frame
Mode (DF/NDF)
Press the [F9] (DF/NDF) button to select the running
mode for the CTL counter and the time code generator.
DF:  Drop frame mode
1)
 (DF is displayed.)
NDF:  Non-drop frame mode
2)
 (NDF is displayed.)
auto: The unit switches to drop frame mode when the
field frequency is 59.94 Hz, and switches to non-
drop frame mode when the field frequency is
60 Hz.
Note
• This setting is only active when the frame frequency
of the unit is 29.97 Hz or 30 Hz.
• When the [F7] (TCG MODE) button is set to regene,
the drop frame mode is inoperative since the time
code generator is synchronized to the playback time
code.
