When you use unauthorized memory cards, the product cannot record videos correctly and your recordings may be lost.
The memory cards released after this product was released may not be compatible with the product.
To ensure stable recording and playback, use 4MB/s (Class 4) or higher memory cards.
Micro SDHC and micro SDXC cards are a higher version of micro SD memory cards and support higher capacity than micro SD memory cards.
Use micro SD cards only with micro SD enabled host devices.
Hopefully this is of some help to you.
