SD Card / USB Flash Drive Mounting Functions


    • AKD PDMM and PCMM use SD cards.
    • PCMM2G uses a USB flash drive as removal media for File Management functions.
      • PCMM2G uses an auto-mount feature for USB Flash Drive.
      • With auto-mount enabled, removable media is automatically mounted upon insertion and safely unmounted upon removal.
      • This eliminates the need to invoke mount and unmount functions before performing any file management tasks.
