i When the recording mode setting is set to audio recording <, and the
recording exceeds about 5 hours, the recorded file is saved and the audio
recording ends. For other recording mode settings, when the file size
exceeds 4 GB, the recorded file is saved once, and the recording continues
in a new file. (These 4 GB segments are automatically created. The
recording session continues until you stop recording.)
i Even with cards of the same capacity, the amount of data that can actually
be stored may differ depending on the card brand or type, recording
conditions, etc.
i The continuous recording time may differ depending, for example, on the
card type, capacity, efficiency, etc.
