* "AUTO" (Automatic follow-up system)
The purpose of this white balance of "AUTO" is for a TV monitoring
system, which installed to shoot a scenery
with wide angle. This automatic white balance adjust-
ment is performed by the detection of the average
picture levels of red(R), green(G), and blue(B) signals picked up from
the subject while they are balanced.
Under the proper condition, this incorporated function
is automatically compensated and follows up the white balance for
color temperature even when the camera is panned during shooting,
changed the color temperature of
a light source or changed ambient condition while "AUTO" position.
However, this control system is not always perfect, for example, under
a fluorescent light or when shooting and closing up a subject with
large colored area, this
control system cannot work properly and also cannot
obtain good color-imetry (color reproduction).
The purpose of the "AUTO" position is for TV monitoring system for a
scenery with a wide angle. If white balance adjustment ,is not
possible, use "AUTO SET" position.
* "AUTO SET" (Data holding)

not change anything even if changed the illumination on subject and
the data will be held for about 5 hours
backing up the data.
Normally, set it "AUTO SET" position.
If you shoot more than 5 hours after the last white adjustment, or
when lighting conditions change,
re-perform white balance adjustment.
