6.3.1 Sound data playback
Where the copy data contains sound data, follow the operation below to play it back.
[Asynchronous playback]
Check [sound output]. Select [playback ch] from the dropdown menu. Set the playback to
[asynchronous]. Start the playback. Stop it where you wish to hear the sound data. the
system plays back the sound data before and after the point you stopped. Adjust the slide bar
on the right side to change the duration of the playback in three steps. The actual time for the
sound data playback depends on the frame rate of the recorded images. Adjust it for each
playback occasion.
[Synchronous playback](applicable for some types of recorders only)
Set the playback to [synchronous] to play back the sound data. You can play back the data
downloaded from the network in blocks and sound data copied on the recorder simultaneously
with the images. At this stage, displayable image channel is restricted to one screen. The
sound cannot be heard in a special playback mode (such as fast forward and reverse playback)
other than the normal playback. The Lip sync requires adjustment according to the PC you use
or the condition of recording the playback data. In some cases, there can be no point where the
sound and the image match each other.
Notice
z
Some data may not appear on the screen or allow you to operate depending on types of
recorders used for recording.

The synchronous sound playback skips some image updating depending on the
processing capacity of the PC. For the playback to prioritize the images, select
[asynchronous].
