It is possible to record exceeding 2GB
The recording will continue even if the volume of a single file exceeds 2 GB in the linear PCM
format recording.
•
The le is saved every 2 GB in separate les. It will be treated as multiple les when playing back.
• When the recording exceeds 2 GB, the number of les in the folder may exceed 999 les.
The 1000nd le and later will not be recognized by the recorder, so check by connecting
the recorder to a PC.
Notes
• The above values are strictly rough guides.
• Variations in the available recording time will arise as there may be dierences in the available
memory depending on the microSD card.
• Caution is required, since the dierences in the available recording time will increase when
the bit count and bit rate are low.
• Available recording time may be shorter if many short recordings are made (The displayed
available recording time and recorded time are approximate indications).
