, and the adjustment
value is stored in memory A or memory B.
When the CC FILTER control and the WHITE BAL
switch are set to the same positions as they were
when adjustment was performed, the adjustment
value stored in the memory is recalled, and the unit
is automatically adjusted to the white balance that
corresponds to this value.
If this switch setting is changed while the menu
display mode is set to “3” (default setting), the new
setting will appear at the WHITE BAL switch display
position on the viewfinder screen.

SDI switch
This is used to select the video and audio signals
which are to be output from the HD SDI OUT
connector and the audio signals which are to be
output from the AUDIO OUT connectors.
EE/PB:During playback, the playback video and
playback audio signals are output; in all
other modes, the EE video and EE audio
signals are output.
EE:The EE video and EE audio signals are
output at all times.
OFF:Signal output is stopped.  (This serves
effectively as a power-conserving mode.)

With the settings at shipment, this function does not
work at the OFF position when a cable is connected
to the HD SDI OUT connector.  For further details,
refer to the FUNCTION screen (page 95) of the
VTR menu.
During recording, the HD SDI OUT output signals
cannot be switched from ON to OFF or vice versa.

VTR START button
When this is pressed, recording starts; when it is
pressed again, recording stops.
This button functions in the same way as the lens
VTR button.=
VTR SAVE/STBY (tape protection) switch
This is used to select the power supply mode when
the VTR has temporarily stopped recording (REC
PAUSE mode).
SAVE:This is the tape protection mode.  The
cylinder is stopped in the half-loading status.
Less power is consumed than at the STBY
position, and the operating time provided by
the battery is prolonged.  Compared with the
STBY position, it takes longer for recording to
commence after the VTR START button <
has been pressed.
When the switch is set to this position, the
VTR SAVE lamp inside the viewfinder lights.
STBY:At this position, recording is commenced as
soon as the VTR START button is pressed.

When the prescribed amount of time has elapsed in
the STBY mode, the unit is automatically set to the
SAVE mode.  To return the unit to the STBY mode,
set the VTR SAVE/STBY switch to SAVE, and then
again to the STBY position.
