The following is a list of guidelines to help choose a compatible SD card for the R-09:
The SD card size that used depends on the current software version that your R-09 has. To view the current version, turn on the power. As the R-09 is booting up, the version appears in the lower left corner of the display.
If needed, the R-09 can be updated from the following link:
64MB - 32GB capacity
NOTE: Although a 32GB SD card can be used, the R-09 will be able to use no more than 16GB of the card. This means that the other 16GB on the 32GB SD card will be unusable.
64MB - 8GB capacity
64MB 4GB capacity
Secure Digital (SD):
64MB - 2GB Standard SD memory (any standard speed)
2GB - 32GB SDHC (Class 2, Class 4, or Class 6 is recommended)
Using Major brands like Toshiba, Sandisk, Panasonic, Kingston, and Lexar is recommended.
