Make sure that the sonar/echosounder settings are according to specifications in this chapter before starting to log.
For instruction on how to start a recording, refer to the documentation for your MFD or sonar/echosounder unit.
When you start a recording, a dialog is displayed. In most circumstances, the default logging criteria are sufficient. For smaller file sizes, you may want to choose the .sl2 file format.
Due to limited internal storage it is recommended that logs are saved to a memory card.
