Deleting the Recorded Files

You can delete the recorded data files using the keypad/display, or the
DELETE command on the serial line. The deletion is always done for all
data; you cannot delete individual files.

Note that the transmitter automatically overwrites the old data when the
memory is full, so manual deletion of the recorded files is not necessary
in normal use.

To delete the data files using the keypad/display:

Press any of the arrow buttons to open the Main Menu.

Select System and press the right arrow button.

Select Clear graph memories by using the down arrow button.
Press the CLEAR key. Confirm by pressing the YES key.

CAUTION

This function clears the entire data history of the transmitter, including
all graphs and the content of the optional data logger module.

UNDELETE

Similarly to the DELETE command, the UNDELETE command is used
without any arguments. It will recover all deleted data that has not been
overwritten yet.
