"Tips"

1) With this product, showing images recorded with PC or DSC enables you to check the playing system.
2) With PC, showing images recorded with this product enables you to check the recording system.
3) Video is played at the rate in sync with IIS CLOCK signals from audio circuit. For example, if the IIS CLOCK

signals fail to reach the card playing circuit for some reason, the video is played at the lowest rate and is shown
in slow motion.
