If you have no time to adjust the white balance
Set the WHITE BAL switch to PRST. The white balance is
automatically set to 3200 K when the FILTER selector is in position B,
to C for 4300 K and to D for 6300 K.
For details about setting the white balance manually, see "4-1-2 Adjusting the

White balance memory
Values stored in memory are held until the white balance is next

adjusted.
There are two sets of white balance memories, A and B, and adjustments
for each of the filters can be automatically stored in the memory
corresponding to the setting (A or B) of the WHITE BAL switch. The
camcorder has four built-in filters, so a total of eight (4 2) adjustments
can be stored. The number of memories allocated each A and B can be
limited to one each by setting WHT FILTER INH. to ON on the
FUNCTION 3 page of the MAINTENANCE menu. In this case, the
memory contents are not linked to the filters.
When the WHITE BAL switch is set to B whereas, on the FUNCTION 2
page of the OPERATION menu, "WHITE SWITCH <B>" 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. Contact your Sony
representative if this message continues to appear even after the white
balance and black balance have been adjusted again.
