User's Manual
Notes on SD Cards & USB Flash Drives fro Recording:
1. Performance of an SD card memory is much better than that of a USB flash drive. The SD card is
highly recommended as your first choice for recording.
2. To obtain the best performance, this apparatus requires writing speed of flash memory better than
2 MB / sec for recording.
3. To use a USB drive for recording, SanDisc Cruzer Blade series and SanDisc Cruzer Switch series
are highly recommended. (USB flash drive: 128K)
4. When SD card can not be read, press delete button for 6~7 seconds, then choose “Format”.
5. After setting the parameter, this apparatus still has the function of memory protection even if power
supply is interrupted.
