Updating System Software
To safely update the system software:
1.
Turn off the MDR-304A.
2.
Insert the SD card into the built-in SD slot.
3.
Turn on the MDR-304A.
4.
The MDR-304A sounds a tone and displays the
message “
XXXXXX BYTES READ
”. Now the
MDR-304A is updating the system software, which
will take approximately 90 seconds to process.
5.
The MDR-304A displays the message “
PLEASE
REMOVE SD CARD
”. The process is complete.
Please remove the SD card, and the MDR-304A will
restart automatically. (If you have already followed
procedures 1 ~ 5 and the unit is still unable to turn on,
then please first check if the SD card you are using
is functioning and the file is intact. And then start
procedures 1 ~ 5 all over again.)
6.
Verify the version of the system software.
Caution
:
1. Before carrying out the updating procedures, please
ensure the SD card is working and the file of the
system software is intact.
2. Don’t interrupt the process while the unit is updating
itself, as this will cause the unit to crash.
3. Contact Brigade Electronics for latest software
version.
