DISPLAY switch EXT-LOCK/U-BIT switch
This selects which time code is displayed in the status
indication panel (see page 2-4). This switch is only
effective when the DISPLAY switch by the status
indication panel (see page 2-5) is set to the TC or U-
BIT position.
LTC: Display the LTC (Longitudinal Time Code).
VITC: Display the VITC.
This selects whether or not to lock the user bit data to
external user bit data.
ON: The user bit value is locked to the user bit value
inserted in the external time code.
OFF: The user bit value set on this unit is used.
DF/NDF switch (DVW-250 only)
F-RUN/R-RUN (free-run/record-run) switch
This selects the operating mode of the internal time
code generator.
F-RUN: The time code generator keeps running,
regardless of the operating state of the unit. Use
this position when setting the time code to real
time or synchronizing it to an external time code.
SET: Move the switch to this position when setting
the time code or user bits value.
R-RUN: The time code generator runs only while
recording. This produces a tape with consecutive
time code values, even when shot intermittently.
This selects whether to use drop frame mode or non-
drop frame mode.
For an explanation of the significance of these modes, see
the footnotes on page 4-9.
DF: drop frame mode
NDF: non-drop frame mode
