Press the PREROLL button.
The VTR now performs the preroll operation.
When the edit IN point has been entered, the tape is rewound from the edit IN point
for the duration set by setting menu “000,” and the unit then goes into the stop mode.
When the edit IN point has not been entered, the tape is rewound for the duration set
by setting menu “000” from the position where the button was pressed, and the unit
then goes into the stop mode.
<Notes>
The time code or CTL signal must be continuously recorded between the edit IN point and
preroll point.
When the IN point has not been entered, whether to enter the IN point and perform preroll
or to perform preroll without entering the IN point can be selected at setting menu No. 311
(AUTO ENTRY).
