When you are using a SD Memory Card, make sure that the protect switch is
set to allow recording.
Do not turn off the camcorder, change the position of the TAPE/CARD switch,
disconnect the power source, open the memory card cover or remove the
E
memory card while the card access indicator is flashing. Doing so could result
in data damage.
About the focusing frame:
This camcorder uses the 9-point artificial intelligence auto focus (9-point AiAF)
that will automatically select the best focusing frames out of nine available. The
way the focusing frames are selected varies depending on the recording mode
and can also be changed manually ( 86).
If the subject is not suitable for autofocus, turns yellow. Keep the PHOTO
button pressed halfway and adjust the focus manually with the SET dial.
When recording a still image (step 3), the image may appear out of focus for a
moment while the camcorder is focusing.
When the subject is too bright, "OVEREXP." starts flashing. In such case, use
the optional FS-34U ND filter.
Sound for movies recorded on the memory card will be monaural.
When you use a SD Memory Card, we recommend using a Canon SD Memory
Card, or a SD Memory Card with a transfer rate of more than 2 MB/sec., right
after you have formatted it with this camcorder. With memory cards not
formatted with this camcorder, or when recording/erasing has been repeatedly
performed, the writing speed may be lower and recording may stop.
When powered by a battery pack, the camcorder shuts off after 5 minutes when
the camcorder is left without any operation to save power ( 68).
Approximately 30 seconds before the camcorder shuts off, " AUTO POWER
OFF" appears in the center of the screen. If the camcorder shuts off, turn the
POWER switch to OFF and back on again.
