When you insert the SD card, power on and start the device. The first time for stating the device takes longer time to stay on the "Waiting For Playing Programme" window than not inserting the SD card. This is the normal situation because the device is formatting the SD card for initial using and it will not take a long time when the SD card is inserted the second time. Therefore, do not power off the device when inserting the SD card and starting the device for the first time. To better use the SD card and ensure the data correctness, the ext2 file system of SD card supported by the device will be formatted. Note that the SD card with the ext2 system cannot support viewing files in the Windows XP operating system.
