To end the menu operation, set the MENU ON/OFF
switch to OFF.
The menu disappears, and the display indicating the
current status of the camcorder appears along the top
and bottom of the viewfinder screen.
Settings made in Picture Cache mode are maintained until
changed.
You can turn Picture Cache mode on and off by assigning
the Picture Cache ON/OFF function to one of the
assignable switches (ASSIGN 1/2 and TURBO GAIN),
and pressing the switch.
For detailed information on the assignable switches, see
“5-3-5 Assigning Functions to Assignable Switches” on
page 90.
Camcorder operations in Picture Cache mode
The recording procedure in Picture Cache time is basically
the same as that for normal recording. However, note the
following differences.
• When you record in Picture Cache mode, the picture you
shoot is recorded to tape after the Picture Cache time
elapses. For this reason, the tape does not stop
immediately when you press the VTR START button.
After the VTR START button is pressed, all tape
operation buttons (EJECT, REW, F FWD, PLAY, and
STOP) stop functioning until the Picture Cache time has
elapsed. During this time, if you press the VTR START
button or the VTR button on the lens, recording starts
again as if there were no pause in recording.
• The time the tape stops after the VTR START button is
pressed equals the Picture Cache time set. However, if
you start recording within the set Picture Cache time
immediately after selecting the Picture Cache mode,
changing the Picture Cache time or performing playback
or recording review, the picture data for the duration of
the Picture Cache time will not be stored in memory.
Thus, the time the tape stops after the STOP button is
pressed becomes shorter than the Picture Cache time.
• The time code stops advancing while time data is being
set (when the F-RUN/SET/R-RUN switch is set to SET).
For this reason, if you start recording immediately after
switching to F-RUN or R-RUN (i.e., to a position other
than SET), you may overwrite a portion of the previously
recorded time code.
• Positions of essence marks, such as shot marks, may be
shifted depending on the Picture Cache time setting.
• Menu operation for the Picture Cache time setting is
disabled during recording. To change the setting, once
stop the recording by pressing the VTR START button or
the VTR button on the lens.
When power is lost during recording
• When the power is turned off during recording, the
camera will switch off by itself after the tape has run for
a few seconds.
• If you remove the battery, pull out the DC cable, or cut
power to the AC adaptor during recording, actual
recording of picture data ends the instant the tape is
stopped. However, a certain amount of recorded picture
data, equal to that recorded during the Picture Cache
time, will be lost, because it has not yet been recorded on
the tape before the tape stops. For this reason, make sure
you do not change the battery while recording.
When the tape runs out during recording
Please note that if the tape runs out and the camcorder
stops during recording, a certain amount of recorded
picture data, equal to that recorded during the Picture
Cache time, will be lost, because it has not yet been
recorded on the tape.
3-2-5 Shooting Picture at Intervals
(Interval Rec Function: with CBK-
MB01)
Inserting an optional CBK-MB01 extension board in the
camcorder enables the camcorder to record pictures at
various intervals. There are two kinds of Interval Rec
mode:
Auto Interval Rec
In Auto Interval Rec mode, pictures are automatically shot
a frame at a time at the specified interval and stored in
memory. To use this function you must set the total time
for shooting (TAKE TOTAL TIME) and the length of time
for recording on the tape (REC TIME).
Manual Interval Rec
There are two modes of Manual Interval Rec:
• Single Trigger mode
Setting the number of frames to be recorded at one
shooting (NUMBER OF FRAME) enables the
camcorder to record the number of frames preset each
time the VTR START button or the VTR button on the
lens is pressed.
• Continuous Trigger mode
Pictures are automatically shot by preset frames at preset
intervals by pressing the VTR START button or the VTR
button on the lens.
In Auto Interval Rec and Continuous Trigger mode of
Manual Interval Rec, by setting the PRE-LIGHTING
function to ON, the light connected to the LIGHT
