built-in filters, so a total of eight (4 X 2)
adjustments can be stored. The number of
memories allocated to each of A and B can be
limited to one by setting the WHT FILTER INH.

MAINTENANCE menu. In this case, the
memory contents are not linked to the filter
settings.
If the WHITE BAL switch is set to B, and on the
FUNCTION 2 page of the OPERATION menu,
the WHITE SWITCH <B> item is set to "ATW",
the ATW function is activated to automatically
adjust the white balance of the picture being shot
for varying lighting conditions.
If a memory error occurs
If the error message ": STORED DATA : NG"
flashes on the viewfinder screen when the
camcorder is turned on, the white balance and
black balance memory contents have been lost.
Adjust the white balance and black balance again.

Notes
• Whatever the operating mode of the electronic
shutter, the sensitivity of the CCD decreases
with increasing shutter speed.
• When the automatic iris is used, the iris opens
wider as the shutter speed increases, thus
reducing the depth of field.
• Under artificial light, particularly fluorescent or
mercury lamps, the light intensity may appear to
be constant, but the red, green, and blue
intensities are actually changing in
synchronization with the frequency of the
power supply causing flicker. Using an
electronic shutter under such lighting could
make the flicker even worse. Color flicker is
particularly likely to happen when the power
supply frequency is 60 Hz or 50 Hz. However,
if the power frequency is 50 Hz or 60 Hz, setting
the shutter speed to 1/100 or 1/60 can reduce
this flicker.
