Preparing the SD Card 

 

The DM-8 message player requires an SD card (or microSD with adaptor) to read the message and schedule information 
from. The SD card should be formatted to FAT32 and is recommended to be between 4GB and 32GB in capacity. 
 

NOTE

: It is necessary to use a new or completely blank 

SD card. If re-using an existing SD card, it must be fully 

formatted using the application calle

SD Memory Card 

Formatter

, which is available at the 

sdcard.org

 

website. The standard 

Format

 function provided by 

your PC operating system does not always remove all of 
the data and the SD card might not work with the DM-8. 

 
If pre-recorded messages are to be used, these must be 
in standard mp3 audio format and stored to the root 
folder of the SD card with file names as follows

  

M001

.mp3, 

M002

.mp3, 

M003

.mp3

 

M099

.mp3

  

 for up to 99 message tracks.  

 

The message tracks must be stored into a folder called 

MESSA

, which itself needs to be in the root folder of the 

SD card, for the DM-8 to recognize them. 

 
The message schedule must be stored on the SD card as 

a text file, named as 

schedule.txt

 which can be created 

using the free 

DM8_Schedule_Editor.exe

 application. 

 
This application is downloadable from
