seconds before starting recording
(PRE-RECORDING function)
By always storing a few seconds' worth (maximum of 7
seconds) of audio and video data shot by the camera, it is
possible to record video and audio signals a few seconds
before recording is actually started by pressing the REC
START button or the VTR button on the lens in the built-in
memory.
In order for this function to be used, it is necessary to open
the <REC FUNCTION> screen from the SYSTEM SETTING
page and set the data storage time in memory using the PRE
REC MODE item and the PRE REC TIME item using the
menu operation.
PRE REC MODE
ON: PRE RECORDING function is activated.
OFF: Recording starts about 0.4 seconds after pressing
the REC START button or the VTR button on the
lens.
If you stop recording by pressing the REC START
button or the VTR button on the lens, the message
"TAPE ¢S" will be displayed on the viewfinder
screen.
PRE REC TIME
From 0 to 7 seconds:
A value from 0 to 7 seconds is set as the length of time
for which the video and audio signals can be recorded
before the REC START button or the VTR button on
the lens is pressed.

<Notes>
≥ If the PRE REC MODE items is set to "OFF", recording
starts about 0.4 seconds after pressing the REC START
button when the VTR SAVE/STBY switch is set to either
SAVE or STBY position.
If the PRE REC MODE item is set to "ON," video signals
for the time set in the PRE REC TIME item before starting
are recorded.
≥ The data contained in the storage memory becomes
unstable immediately after the power is turned on,
immediately after the PRE REC MODE item setting is
selected or its set time has been changed, and
immediately after playback or rec-review has been
performed. Immediately after any of these operations,
therefore, the video and audio signals will not be pre-
recorded for the duration set when recording is started by
pressing the REC START button or VTR button on the
lens.
≥ The video data and audio data are not stored in the
storage memory while playback or rec-review is being
performed. This means that the pre-recording will not
include the video and audio signals supplied during a
playback or rec-review operation.
≥ When recording has been started, the time code (TCG)
display may remain in the hold status until it is possible for
the time code (TCR) on the tape to be read.
