Remove SD Card safely
In the case the SD card is taken out without precaution, the current
open file is not closed properly and will have a content of zero bytes.
The appearance in the directory remains. Also, there is a very small
chance that the directory or some file gets corrupted by doing so.
Therefore, to take out the card safely it is recommended to close all files
first with the following procedure:
•
Press the button
: All LED’s are ON
.
•
Hold pressed for 2 seconds: Amber and Blue LED go OFF.
•
Release the button: Amber LED starts flashing.
•
Take out the SD card safely now.
NOTE: When the Blue LED is not blinking, then no recording is busy, so
no data is written, in which case the SD card can just be taken out.
