Note
•
Do not block the infrared sensor (see "Terminology" on
page 148) with hand, etc.
•
If a optional-user provided tele or wide-conversion lens is
used, the auto white balance may not operate depending
on the recording conditions. If this happens, set the mode
to match the recording conditions, or manually set the
white balance.
•
Be sure to remove the lens cap before turning the DVD
Video Camera on: If the DVD Video Camera is turned on
with the lens capped, the white balance will not work
normally.
