Shoot the white object so that it fills the screen, and set the AUTO
W/B BAL switch to AWB.
The white balance adjustment is completed is about 10 seconds.
O
Upon completion of the adjustment, the color temperature display
appears in the viewfinder.
Now check that the color temperature imaged and the color
temperature displayed in the viewfinder match. If they do not tally, it is
recommended that the white balance be adjusted again.
O
If it was not possible to adjust the white balance, the WHITE BAL
ERROR TRY AGAIN message appears in the viewfinder. In a case like
this, check that the lens cable is connected properly and that the
subject brightness is suitable, and then adjust the white balance again.
Notes: $ Since hunting may occur when a zoom lens with an automatic iris
mechanism is used, adjust the iris gain knob provided on the lens.
For further details, refer to the operating instructions
accompanying the lens.
$ The white balance cannot be adjusted if the white balance selector
switch is set to the ATW or PRST position.
$ Do not allow a subject lighter than the white object shot in step
3
above onto the screen since the white balance is adjusted with the
lightest part of the subject on the screen taken to be white.
Failure to heed this caution may cause malfunctioning.
$ Do not increase the gain to an unnecessarily high value and then
proceed with the automatic white balance (AWB) operation.
Failure to heed this caution will cause the iris to be nearly stopped
down when AWB is performed so operation will become unstable.
Remarks: $ In order to ensure that a high picture quality is maintained, it is
recommended that AWB be performed immediately before
shooting scenes of great importance or value.
$ When the white balance is adjusted, the black balance is also
adjusted automatically inside the unit. Consequently, when the
AUTO W/B BAL switch has been operated, the iris will close
before opening again: this is normal and not indicative of any
malfunctioning.

When the white balance should be re-adjusted:
Be absolutely sure to re-adjust the white balance when there has been a
change in the light conditions or when the gain setting has been changed.
How to use the
automatic tracking white
(ATW) balance mode
The automatic tracking
white balance mode is
established when the
white balance selector
switch (AUTO W/B BAL) is
set to the ATW position.
However, since the
ambient light conditions
may make the auto
tracking white balance
operation unstable, learn
how to use the MEMO,
PRESET and ATW modes
to best suit the prevailing
conditions.
Examples
O When shooting a
subject illuminated by a
spotlight, proceed in the
PRESET (INDOOR
mode).
O If you know ahead of
time that you will be
shooting a subject
outdoors, store the
white balance setting in
the MEMO position.
O Shooting a subject
illuminated by a mixture
of light from fluorescent
lighting and
incandescent bulbs or
by a mixture of outdoor
light and fluorescent
lighting because the
subject is by a window
presents difficulties for
automatic tracking.
Under conditions such
as these, adjust the
white balance manually.
Use the ATW balance
mode only in an
emergency when you do
not have the time to
adjust the white balance
manually.
