Hot swap recording

Recording can span over two memory cards by inserting memory cards into the card slot 2 and the card slot 3.

Also, the memory card other than the one currently being recorded to can be swapped and recording can be continued on two or more memory cards.

Note, however, memory card recognition might slow down depending on the timing (immediately after pre-recording or before and after continuous recording across two card slots) that the memory card is inserted. When inserting a memory card, make sure that there is at least one minute of remaining recording capacity on the memory card to be recorded to.
