They might differ dependingon the SD/SDHC/SDXC card in use.• The recording times shown above are not continuous recording times, butrather they are the total possible recording times for the SD/SDHC/SDXC card.• If recorded in mono WAV format, the maximum recording time will be doublethe figures above.• When using dual/4-channel recording in WAV/BWF format, the maximumrecording time will be about half the figures above.
