File, Save As
Save the show by going to Setup>Files>Save As. The show will be saved with the name you enter. Use only alphanumeric characters, and avoid symbols.
Note: The difference between Save and Save As is you will always be asked to name the show file when you use Save As.
CAUTION: All data is stored internally in non-volatile memory. Do not switch off the power until any pending save operation is completed, or you may lose data. It is strongly advised that you make periodic backups of important data to an external memory stick using the Export function.
