Konica Minolta Q-M100 - Manual (Page 79)

To cancel erasure protection of a selected frame:
With the display of the figure 3B, press the SET button.
The selected picture is released from erasure protection and the display
returns to the status of the step 1.
If the MENU button is pressed for the SET button, the display returns to
the status of the step 1 without canceling the erasure protection of the
frame.
●
Be careful not to change any attribute of a picture file that has been
protected against erasure with a personal computer, because the camera
may fail in reading a file if its attribute is changed with a personal com-
puter.
