NOTE: If you experience long pauses when recording a performance, you should consider reformatting the
memory card or reducing the number of files on it, whether it is being used alone or in a USB carrier. Too
many files on the memory card can occasionally delay the recording process. Always use high-quality memo-
ry cards, Class 4 or better.
