If you intend to delete the original scenes or still pictures when the copying has finished,
always play back the duplicate scenes or still pictures on PC before deletion to confirm that
they have been copied normally.
≥ Copying can be performed even when the battery is used for power, but we recommend that the
AC adaptor be used.
≥ Once scenes or still pictures are copied to a PC, the original scenes or still pictures cannot be
copied to any PCs.
≥ If the total length of the scenes recorded on the same date on the SD card exceeds
approximately 8 hours, the scenes will not be copied.
≥ If the copy source contains scenes or still pictures recorded on other devices, copying may be
canceled.
≥ Depending on your environment, copying may take time or may not be available.
≥ If the scene to be copied is long or copying fails, we recommend that the following be performed
for copying.
