delete ecg from storage

Here is what I found in the manual:

An ECG may be stored in the directory but have a “delete status” (indicated by “X”). The directory saves records marked for deletion in the event that you may want to recover the ECG at a later time. Records are automatically marked for deletion based on the delete rule configuration (see Section 4). To manually mark an ECG record for deletion, highlight a name from the ECG directory and select F4 (Delet). An “X” will appear in the far right-hand column of the directory. To remove the delete status, re-highlight the name and select F4 again. All stored ECGs will remain in the directory until it becomes full. When necessary to store a newly acquired ECG, only those records that have been marked for deletion will be removed.

To delete all records follow these key strokes: Delete all ECGs. F6 – #3 – Up-ALT-C – admin – Up-ALT-f
